The Post-Pesticide Age

During the NZ Horticulture Conference in Christchurch last week it was intriguing to listen to the panel discussing the potential possibilities and products for a post pesticide age, the opinion and thoughts of all four speakers on the panel was informative and based on sound findings. Each panel member discussed a different alternative in great detail and how it could contribute to the reduction of pesticide use.

The four panel members were:

Alison Stewart, Foundation for Arable Research
Dr Charles ‘Merf’ Merfield, BHU Future Farming Centre
Dr Steve Wratten, Lincoln University
Robbie McCormick, Mr Apple

 

Dr Steve Wratten, from Lincoln University, talked about the need to keep researching “good insects” and the need to create a favourable environment for them to thrive.  One example Dr Wratten discussed was the use of buckwheat as a supplement for Tamarixia.  The nectar from buckwheat will allow the Tamarixia up to 43 days to survive and do its job, without the nectar the Tamarixia will only work for up to 3 days.  Tamarixia have been released into a greenhouse in NZ as a trial, ( Tamarixia is not yet commercially available for growers to release but Plant and Food are working on breeding it for wider release, beyond experimental work). information like this is so important for the Tamarixia to be a success for greenhouse growers wanting to control Psyllid populations. 

Another important piece of work Dr Wratten has been involved in, which could help NZ greenhouse growers, is a programme releasing Green Lacewing, a whitefly predator, into greenhouses to determine how effective it will be controlling greenhouse whitefly.  It is an introduced species to NZ.

Dr Charles Murfield’s alternative was the use of physical management to control Psyllid, by using a mesh to cover potato crops and create a physical barrier to prevent contact with the crop.  Dr Murfield also carried out a study using UV lights in a small netted greenhouse to attract psyllids to sticky traps.  The results were very conclusive and showed how this technique proved excellent for trapping psyllids.   Unfortunately, for greenhouse growers, not many have netted greenhouses and the use of UV lights to trap psyllids could be counterproductive and potentially attract more psyllids and moths into the greenhouse.  Insect screened greenhouses are a great option and I believe using nets is an option and possibly the best defence from pests. 

 

Robbie McCormick from Mr Apple, showed the audience a video of his company using Sterile Insect Treatment in the Hawkes Bay to reduce (almost eliminate) Coddling Moth.  By releasing sterile Coddling Moths there had been a 98%+ reduction in the detection of coddling moth in the orchid, truly fascinating.  As Alasdair McLeod summed up, “moths with condoms”. There was no mention of anything like this being available for greenhouse pests but wouldn’t that be nice.

 

For me the most interesting presentation was given by Alison Stewart, Foundation for Arable Research. Alison’s talk on Bio-pesticides was very educational.  The two main categories that were discussed were:

A, Microbials; Fungi, Bacteria, Viruses and Protozoa

B, Bio-chemicals: Plant Extracts, Pheromones, Soaps, and Fatty Acids

 

These are then broken down and developed into four sub categories;

  1. Bio-fungicides
  2. Bio-nematicides
  3. Bio-insecticides
  4. Bio-herbicides

Bio-fungicides and bio-insecticides are familiar to most NZ growers, there are only a handful of bio-nematicides which I am not familiar with and I don’t know any bio-herbicides.  What is of interest is the amount of global Bio-pesticides available worldwide and what we have available in NZ. In the United States there are over 350 registered Bio-pesticides compared to the handful of Bio-fungicides and Bio-insecticides available here.  The message I have taken away is we could be doing a lot more research on already developed Bio-pesticides and finding ways to apply them to our circumstances.  As in other areas of our industry we are lagging behind the rest of the world and therefore still rely too much on old fashioned synthetic chemicals.  

In conclusion, the panel made up of four highly educated people all believe that we have other ways and means to control pests and diseases and that we actually don’t need to have total reliance on traditional chemicals.    Chemicals are still hugely important and necessary.   Looking to the future, new developments of bio-pesticides will hopefully be all growers need, and reliance on traditional pesticides will be a thing of the past.

Zespri is Gold

Kok Hwee Ng from Zespri is marketing kiwifruit to the world

It was a true privilege to be able listen to, and be educated by, the presentation from Kok Hwee Ng, Global Marketing Director for Zespri International.  Her talk included examples of marketing campaigns to Asia, which is an increasingly growing and important market for kiwi fruit.  Kok Hwee specifically covered ‘marketing and how it is consumer centric.’   Customer-centric marketing is a strategy that places the individual customer at the centre of marketing design and delivery. It starts from the realization that there is no “average” customer. Customers have different behaviours and preferences – and this presents rich opportunities to move past a “one-size-fits-all” marketing approach.

The main campaign she showed us was the campaign targeting 30 plus year old females in China.  This woman works hard, come’s home and takes care of the ‘well-being’ of the family.  The advertising is trying to empower women and to demonstrate how an ordinary woman can blossom whilst juggling the demands of family and work life.  The Chinese, 30 plus modern women are identified as the decision makers when it comes to purchasing the weekly needs of the family.  While shopping she identifies all of these positive emotions and makes an emotive empowered decision to buy Zespri Kiwifruit.  The results have been undeniably successful, according to the figures presented by Kok Hwee, dramatically increasing the number of kiwi fruit sold to the Chinese market. The psychology involved in a campaign like this is quite astounding.   

 

In Japan a totally different marketing approach was taken to suit a different culture, by using animation and an iconic Japanese superhero ‘Banana man’ they are able to demonstrate more clearly the benefits of eating kiwifruit to the Japanese market.

 

Advertising targeted to the Japanese consumer

 

Independent campaigns are built for the different markets that Zespri export products to.  This cultural awareness is obviously extremely important to keep growing the Zespri brand.  I think Zespri, and their marketing team, should be congratulated, they deserve a lot of gratitude and recognition for continuing to successfully promote the Zespri brand and New Zealand to international markets, especially Asia.   Well done team.

Nunhems’ new Tomato Variety PROVINE

“Nunhems' new Tomato Variety PROVINE

 

Filling the gap between large Truss and medium Truss”

 

With their new ‘Truss tomato’ or ‘Tomato on Vine’ (TOV) variety, Nunhems wants to fill the gap in fruit weight between the conventional large TOV and the medium TOV. Sebastiaan Breugem, Product Development Specialist: “The market had a demand for a somewhat finer large TOV. Provine (NUN 09196 TOF) * when cut has an average weight of 130 to 140 grams with which the growers offer a good alternative to the large TOV with an average fruit weight of 150 grams and the medium TOV with an average fruit weight of 110 grams.”

During the coffee break it was time to study the tomatoes

 

On Wednesday the 20th of June the breeding company officially introduced the new TOV in the mid-segment of large TOVs. Around twenty interested growers and traders dropped by at the Nunhems Tomato Centre located at tomato grower De Bakker Westland in Kwintsheul, the Netherlands. The results from the tests were examined and, in the greenhouse, a test for unlighted cultivation could be viewed.

Dutch grower, Roel de Bakker, Harm Ammerlaan and Ben Silvertand toasted to Provine

 

Early and high profits:

 

Despite a slightly lower fruit weight, Provine still has a high production rate. Jan Hanemaaijer, International Sales Specialist Tomato: “Until far into the summer, Provine has a production rate that, at the very least, is the same as the main variety and even a little higher. The variety is very generative, produces many flowers easily and has a good coloration. The trusses turn red a bit faster in comparison to the main variety, which means you can harvest 1 or 2 days sooner. To keep the tomatoes generative, you can truss prune to 6.”

 

The early production especially is a big plus in the new type. Sebastiaan: “Especially in the spring you notice you get paid well for the kilos that you harvest. The earliness of Provine can this way increase your profits. During experiments with unlighted cultivation, Provine proved to bring in 2.30 euros more per square meter till week 24 in comparison with the main variety, based on market prizes in 2018. In lighted cultivation growers appeared to be able to get 3.03 euros more per square meter till the 1st of April in comparison to the main variety TOV medium”.

 

Going into the greenhouse to study the ten trial rows from top to bottom.


Provine Neatly fills the crates and saves on labour

 

In his greenhouse, host and tomato grower Roel de Bakker has, between his main variety of large TOV, a test with ten rows of Provine. Without any special help the variety is doing great. Roel is positive about the variety: “The papers have not been signed yet but there is a big chance of that happening. Besides the nice coloration and great taste Provine stands out due to a clean and uniform truss build. The trusses of 6 fruits fit per 6 neatly in a crate of 5 kilos. That is good for presentation but also saves in labour.”

Let There Be Light

Let There Be Light

Solar Glass!! Stop the Bus!

 

At the HFF conference, in Melbourne last month, there were a number of thought-provoking subjects presented and discussed.    Just when I thought I would get a rest another subject caught my attention and got me thinking.   This article focuses on one aspect within the presentation by the CEO of Powerplants, Carl Van Loon, whose overall topic was Greenhouse Coverings.

 

Solar Glass:

Earlier the same day another presentation described technology ‘at warp speed’, in terms of how we currently discuss new technology advances in months, not years.   Later Carl mentioned the potential of Solar Glass that allows 70% of PAR light into greenhouses, at the same time producing electricity- this made me sit up and listen, and what some may say is dangerous, think!!  Just when you think you may have the ideal recipe how to build the perfect greenhouse, another pearl of wisdom comes along.

Be very careful, when considering building new greenhouses, to consider the consequence of fast technological change, especially when technology is rapidly superseded.  Large capital investments have to be made when building greenhouses, and since technology is changing so fast it is very important to ask a number of questions.  None of which are stupid.  Before I become over excited, I want to be considered in the approach of possibly building a greenhouse with Solar Glass.  The idea that we could grow crops and produce electricity using Solar Glass sounds incredible, but I certainly have some reservations that need to be addressed. 

Immediately I thought could electricity produced from a Solar Glass greenhouse support a heating and cooling system as well as supplementary lighting?  However, this throws up a set of new questions I simply don’t have the answers to, but I would definitely be using experts to find out. 

Would enough electricity be produced by a Solar Glass greenhouse, during the winter, to maintain a heating system and supplementary lighting?   Reading a statement from a Solar Glass suppliers website it describes being able to produce 1kw of energy from 10m2 of glass assuming a sunny aspect.  That is too vague.   I would require a great deal more information regarding what range of light intensity and the length of time it takes to produce each KW.  I would use this data to understand how much energy is required to run supplementary lighting on the darkest day of the year and how much energy you would be able to capture/produce on the darkest day of the year.  During Summer, with high ambient temperatures could enough electricity be produced to cool a greenhouse using current cooling systems available?

 

 Growing Questions;

1. How much energy can I produce for different times of the year per m2?

2. How much energy will I need to operate a heating system?

3. How much energy will I need to operate a supplementary lighting system?

4. How much energy will I need to operate a cooling system per m2?

5. Would I need to store my energy and how? (Would location determine how much storage is needed)

6. Would I need added energy from a different source?

7. How important is location?

 

Financial Considerations;

1. Capital investment, what is the cost of installation vs traditional systems?

2. How long will the estimated return on investment take?

3. What is the life span of the ‘Solar Glass’?

 

These are just a few of the questions that I have considered.  I am sure you will have many more as well.   I won’t be rushing to advise growers to build with Solar Glass any time soon but it is food for thought, and with technology changing so rapidly it might not be that far into the future concepts such as ‘Solar Glass Greenhouses’ using only renewable energy become a reality.

Technical: Anti-Condensation Coatings RE-VISITED

How much more light transmission could we have by reducing condensation?

 

July last year I posted the article below.  Yesterday (21st of January) I was reminded how much condensation will prevent natural light penetration.  There are currently many crops being replaced and greenhouses cleaned ready to be replanted for the winter, this is the ideal time to re-read this article and for you to consider applying anti-condensation coatings in preparation for the Winter.  

 

During the HFF Horticulture conference figures were presented regarding the potential increase in light transmitted through a greenhouse by reducing condensation on the glass.  Condensation could be attributed to an average loss of 9% of light.  This is an astounding amount, especially considering how many mature crops we grow in New Zealand though the winter period.   An additional 9% of light is comparable to gold dust for greenhouse growers during the Winter.

If we estimate an increase of light transmission by only 5% for 8 months of the year, there would be positive financial implications.  Comparisons using historical crop data and future crop data using coatings is the only way to 100% confirm the benefits of using anti-condensation products.   Until we actually collect this data we have to trust in the information supplied by independent trials.   The following is an extract from information supplied by Wageningen University, followed by two more articles’ extracts and links.

 

Research by Wageningen UR* shows that the average loss can reach 9%! Therefore, by allowing the condensation layer on the inside of the greenhouse roof to flow away, a large increase in light transmission can be achieved.

New films can have an anti-condensation coating applied in the factory. This coating will last about two production seasons. Films with no (longer) anti-condensation properties can be treated with the AntiCondens coating produced by Mardenkro. This coating has been developed to treat existing films or polycarbonate panels with an anti-condensation layer and it can easily be applied to the inside of the greenhouse. The optimal result is achieved by lightly misting the film or polycarbonate panels and allowing it to dry well. AntiCondens should always be applied well before the condensation season begins. The coating is water-based and safe to use.

* Condensation on the greenhouse roof; C. Stanghellini, V. Mohammadkhani, M.A. Bruins, S. Hemming, P. Sonneveld, G.J. Swinkels – 2010

https://www.redusystems.com/en/innovation/loss-of-light-through-condensation/

 

Other articles written expertly by the team at Mardenkro will supply you with excellent advice.  I recommend the following links:

Spreading condensation = light gain

During cold periods, glass is often constantly wet on the inside. This condensation impedes light incidence by 5 to 8%. The solution is simple: AntiCondens. This coating operates as a spreader and creates a finely spread out water film on the glass instead of large drops. Large drops impede the incidence of light, while a water film enables better transmission. The application of AntiCondens this way significantly contributes to a better light transmission during low-light months. Because light is a limiting factor, better light incidence automatically translates into better production.

Read more click: https://www.redusystems.com/en/innovation/ten-percent-higher-light-incidence-in-greenhouse/?utm_source=rs-1808-en&utm_medium=email&utm_campaign=redusystems

 

Anti-condensation coating for glass

An anti-condensation coating for film has already been on the market for some time but in some instances, this does not meet requirements for application on glass. It is for this reason that an anti-condensation coating has been developed for use on glass. An anti-condensation coating causes the surface on which the moisture condenses to become hydrophilic so the moisture cannot collect on the glass as droplets or thick lines, instead it spreads out evenly to form a thin layer of water. The advantage of this is that it increases the light transmission through the greenhouse covering, such as glass or plastic film. The light transmission gain that is attainable when there is an even layer of condensation can be up to 9% more than with condensation droplets.

Read more click: https://www.redusystems.com/en/innovation/anti-condensation-coating-for-glass-en/

 

The research is compelling, I would be very interested in using anti-condensation products and I recommend you investigate the advantages.  It is important to note that this product should be applied at a specific time of the year.  I would like to thank Barry Zuidgeest, Commercial Manager, Mardenkro, for allowing me to link and publish information from Mardenkro in this article.  For more information on this and other products please go to the link provided below.

Sonny Moerenhout, Born into The Greenhouse Industry

Sonny Moerenhout, Born into The Greenhouse Industry

 

His close ties with New Zealand

 

Sonny Moerenhout, at just 31 years of age, has accomplished a great deal.   Sonny has a history in New Zealand that started here during 2011 when he completed an internship at Gellert Nurseries in South Auckland.  Sonny is now employed as the Sales Area Manager for UK, Ireland, Australia & New Zealand for Grodan.

 

Sonny was born in Oosterhout (NL) in 1987.   He was raised with the greenhouse way of life.  His parents until recently grew eggplants situated at Oosteind, the Netherlands.  The family’s first greenhouse was first built by Sonny’s grandfather in the 1960’s, by 1997 the greenhouse covered a total area of 2.5 ha (with room for expansion of a further 4 ha).  Sonny parents’, Tom & Lisette Moerenhout grew greenhouses crops for more than 25 years. Their growing facility was a modern, high tech structure, including cogeneration capabilities.

 

From a young age, it was clear that Sonny was interested in growing.  After completing high school, he attended Wageningen University in Holland.   He completed a BSc and MSc Plant Science, specializing in Greenhouse Horticulture.  To complete his Master’s degree, Sonny had to complete an internship at a growing facility.  He applied to undertake his internship in New Zealand.  Sonny’s desire to come to New Zealand came from the stories he had heard about our beautiful country.   He was told that surfing and snowboarding was possible on the same day.  The opportunity to see whales, dolphins, our flightless kiwi, not to mention millions of sheep, beaches, such as Ninety-mile beach, as well as the forests’, volcanoes’ and mountains were all irresistible attractions.   

 

During Sonny’s six-month internship he completed a study which looked at the growing techniques, different types of structures and substrates used in NZ.  The study also included the influence temperature and PH has on emergence of tomato rootstocks and the consequence for grafting success.   Sonny believes the graft is very important, as it will impact on plant quality and the total yield growers achieve.

 

On return to Holland Sonny completed his Master’s Degree.  As part of his Thesis, he studied the effect diffused glass has on early cucumber cultivation as well as the change condensation has on light transmission of diffused glass.  Outcomes of this study were the start for ongoing research for the effect condensation has in relation to diffused glass.

 

After finishing university Sonny decided not start his career as a grower but become more involved with the supplier/technology side of the industry.  The knowledge accrued growing up in a family greenhouse business has given him the practical knowledge to start a job and make an immediate impact. 

 

Job History

 

Sonny was employed by SQM as a Market Development Manager. The role involved giving technical support to SQM sales teams’ all around the world, developing marketing tools, providing technical training and presentations about water-soluble fertilizer in fertigation and foliar applications. Sonny travelled to many places including India, China, Indonesia and the Middle East, working with a diverse range of crops including: rice, wheat, citrus, cacao, bananas and many more.  After two years Sonny left SQM, he started a new job as Crop Consultant for Grodan, going back to his roots of greenhouse horticulture.  This role included providing technical support to tomato, cucumber, pepper and eggplant growers in Asia Pacific: Australia, New Zealand, Japan and South Korea. Sonny has travelled to several countries such as Russia, Poland, Turkey and Spain as part of his employment with Grodan.

 

Sonny makes frequent trips to New Zealand, up to four per year.  His vast knowledge and experience is widely respected amongst growers in NZ.   Sonny is no stranger to NZ’s unique growing conditions, advising growers using Grodan’s substrates to achieve better results is made easier having his experience. 

 

Sonny has said “The trend in the world for substrates is growers moving towards higher slabs, in all greenhouse crops. This development is going really fast, as all growers who start with it never go back.”

The benefits observed by Sonny:

 

  1. Gives a more generative start to crops
  2. Quick refreshment, with minimum drain and maximum EC refreshment
  3. Both the WC and the EC can be controlled more quickly and accurately, especially during spring and autumn
  4. A higher slab allows the roots to spread evenly over the total slab height with fewer roots in the more fragile lower areas
  5. The higher slab allows excess water to drain more easily and almost all drainage water to be collected, therefore sustainable use of water.

“Next to that we see growers are steering less on drain percentage, which they did in the past. Steering on what is happening in the slab in relation to water content (%) and EC (mS/cm) is much more accurate. Therefore, Grodan designed the Grosens measurement tool to help growers by controlling and optimizing watering strategy and to improve crop results in production and quality. It will reduce input in water, fertilizer, pesticides & energy so reducing cost of the grower and secure crop results”.

Sonny with NZ Capsicum Grower Gavin Naylor from Freshwest, demonstrating the new Grosens

 

I asked Sonny his opinion on the following questions:

 

1   Where do you see the future of horticulture?

“Interesting times as we see that our industry has a huge amount of data and we growers are collecting it already for many years.We are not able to use the data yet, as most of it is stored in different places. We need to connect all data and get up to speed with Artificial Intelligence (AI) or in other terms ‘Machine Learning’. This will really be the next step moving forward to Horticulture 4.0”.

 

2   How do you see New Zealand greenhouse industry evolving?  Are we keeping up with the rest of the world?

“Not much has changed since I was here in 2011, but growers see now, they need to invest again to be able to compete with the Australian industry where expansions and upgrades of greenhouse systems have been done over the last 5 years. Finally, some movement last 1-2 years in NZ which is absolute necessary and I am happy to see”.

 

3    What do you think of NZ grower’s abilities and where could we improve.

“Steps can be made in adapting towards the next generation of growing (Nieuwe Telen in Dutch). It asks for a different way of thinking from the growers, you need to be open for this. Also, in terms of irrigation the change of steering on % drain towards what is happening in the rootzone is something NZ growers can still work on”.

 

4    Are there new technologies NZ growers should be aware of that could make a difference to our productivity?

“Most important is to make sure the greenhouses are up to date for the coming 10-15 years. AI is something they should be aware of and not be scared of”.

 

5    Where do you see yourself in the future?

“It’s definitely an interesting time in the greenhouse industry. New crops coming up are interesting so who knows. I hope I can keep coming back to New Zealand as I love the country, the people and the atmosphere, and of course, to keep in contact with my All Black friends on the other side of the world”.

 

6   What do you admire about Holland and how it keeps developing new advances in the greenhouse industry?

“The centre of universe for the greenhouse industry is Holland, just as Silicon Valley is for technology. In Holland we need to make sure we keep this position, so investing in research and new technologies is crucial. With the learnings in Holland, I hope to help the New Zealand’s growers in the upcoming years”.

 

I have fond memories working with Sonny in 2011.  Instantly I could tell that Sonny was extremely knowledgeable and could contribute a huge amount to the industry.  He is young so the best is yet to come.  He is a valuable asset, very important to the development and improvement for our industry.

Here Sonny is presenting Root Zone Management strategies at the Greentech 2016 in Amsterdam.

Aspects of Labour Management

Aspects of Labour Management

An insight into a large Australian greenhouse companies labour structures and policies

 

Chris Millis, director of Flavorite Hydroponic Tomatoes, has been growing tomatoes for 25 years.  The family owned business consists of 25 ha of glasshouses in Warragul, Victoria, Australia, including a commercial propagation nursery, packing, distribution and production glasshouses.  The business currently employs 350 staff.

At the HFF conference in Melbourne last week Chris presented aspects of his companies labour management policies.  With an industry well known for a high annual turnover of staff, policies have been put in place to reduce staff turnover to 20% annually.  The cost of labour is over 50% of  Flavorite’s cost of production, it is a major priority to have good, fair, robust policies in place.

 

Flavorite use a strategy called SWOT analysis (Strengths, Weaknesses, Opportunities and Threats)

  1. Strengths: What does your organisation do better than your competition? (Internal)
  2. Weaknesses: What does your organisation need to improve upon? (internal)
  3. Opportunities: What market trends could lead to increased sales? (External)
  4. Threats: What are the advantages competitors have over your organisation (External)

 

There are many challenges that face the business.  It is an industry that employs many young workers.  There is a skill shortage,  the location of the property adds more logistical and accommodation issues especially when the seasonal workers are employed in the summer months.  These are some of the challenges taken into account when setting out employment policy.

With this in mind there are benefits having a recruitment strategy and structures in place to make sure the correct people are being employed.

 

Three key objectives the company is trying to achieve is:

  1. Strong pool of applicants
  2. Accurate screening
  3. Reduced turnover and higher morale

Remuneration practices:

  1. Recognise and Reward
  2. Benchmark (external and Internal)
  3. Fair pay practices

When a person is hired than there are three important phases:

  1. Induction
  2. Orientation
  3. Training

New employees are buddied up with experienced staff members who become their mentors.  Before the new employee starts they are given the opportunity to experience being on a high trolley to get a feel for the work that is involved and that they are comfortable working up high.  Employees expectations can differ so this eliminates disappointment when beginning work in the greenhouses.  This reduces the number of staff who leave after one day or a short period of time as it was not what they expected. 

 

Performance Review:

Orientation is conducted when an employee starts work. They are assessed after day one and again after the first two weeks. It is only if they are successful after these periods KPI’s are put in place.  Probation reviews are conducted at 3 months and again at 5 months with a performance appraisal held at 12 months.

Flavorite encourage general workers to engage with senior staff about any concerns they might have.  It is very important that any issues, such as not liking the music on a particular radio station, are addressed.  The following points are parts of the philosophy behind their labour policies.

Engagement:

  1. Better engagement means better productivity
  2. Engaged employees are less likely to quit
  3. Engaged employees are positive
  4. Employees feel satisfied when they’re engaged
  5. Engaged employees are better communicators
  6. Engaged employees are more creative

 

Flavorite have an incentive plan in place maintaining a strong workforce by rewarding their staff for extra productivity.  They acknowledge staff frequently with gifts, such as baby onesies for staff members who have new arrivals, of course with a Flavorite logo on them.  Attracting new workers is hard work and marketing the industry from different pathways is crucial for capturing the attention of potential new workers.  Some of the avenues are listed below:

 

To improve industry awareness and increase the talent pipeline the following initiatives are used:

  1. Farm Tours: expose students to the industry
  2. Job fairs: markets the industry to students
  3. Work Experience: ‘Taster’ employment during senior school years
  4. Broadening Horizons: Partner with high school students as mentors
  5. SBATs: School based traineeships
  6. Internships: Hosted internships for university students
  7. Academic Partnerships: Scholarships with TAFE and Universities

 

Company Feedback:  “We all need people who will give us feedback.  That’s how we improve”.  Bill Gates, Microsoft.

This is just a brief rundown of the presentation from Chris.  It is an extremely large undertaking to employ over 350 people and it certainly demonstrates how important, in such a competitive job market, having a strong and robust labour management policy is.

Using Screens in New Zealand Conditions

Using Screens in New Zealand Conditions

Its time to start thinking of new options.

 

Last week at the Australian HFF conference in Melbourne a presentation was given by Ton Habraken, Greenhouse Climate Consultant for Ludvig Svensson, about his company’s greenhouse screens and their climate control possibilities.   It was an excellent presentation which has relevance for New Zealand greenhouse growers moving forward.

The use of screens in New Zealand, especially Auckland and North of Auckland, has not always been considered as a ‘must have’, due to our moderate climate.  However, with the introduction of new types of screens, and not just energy screens, the viability of faster returns on investment is now possible.

Some grower’s current structures mean retrofitting is probably not on the cards, but for some existing greenhouses, especially new builds, it is advised to at least do the numbers. 

Years ago, the perception I had was screens would only assist with shade and a small saving in energy.   I was taught many years ago, whilst growing tomatoes, that shading your crop in New Zealand conditions is counterproductive. If you did shade you would create soft plants, less roots etc etc.    In 2018 however, screens have evolved and there are many more options that suit our conditions, which will contribute to energy saving and better light transmission. Newly developed diffused screens act both as an energy screen and light scattering.  Diffused screens are already in many properties in the greater Auckland area, they are especially popular with cucumber, eggplant and capsicums growers.  Imagine, during the hard frosts we had in the mornings last week, if you had a screen which kept the warmth in and allowed light to penetrate into the crop without having to close the screens totally until late in the morning.

The screens available are versatile.  For capsicum growers who need screens in the summer, the Harmony screen, which is used for diffusion, shading and cooling, is an option to be considered.  Tomato growers should consider the Luxous range, which lets more daylight reach the crop while saving energy.  In the warmer months, if you want to protect your crop, you will not be able to use your screens but you can always use diffused coatings on your glasshouse roof to protect your crop.

With what appears to be the imminent arrival of medicinal cannabis growing in New Zealand, Svensson has the Obscura range of black out screens.  These are installed for cannabis growers as they need a set period of darkness each day.  These properties will also be equipped with supplementary lighting. 

For countries in the Middle East, where there is plenty of usable light at the start and end of the day, screening can help reduce greenhouse temperatures by up to 10 degrees in the middle of the day.  Screens are fitted on top of the greenhouse to achieve this!

Harmony = high grade light diffusion

Luxous = energy saving with maximum light transmission.

The Australian Berry Goldrush

The Australian Berry Goldrush

Don’t expect to see high tech systems in Australia just yet!

 

Andrew Olley, well-respected agronomist and consultant, talked about growing berries in low tech structures at the HFF conference in Melbourne last week.  It was interesting as it appears the same low cost, low investment strategy, happening in Australia is also transpiring in New Zealand, with outdoor soil berry growers moving to covered growing in substrates.

Andrew said advice provided by irrigation and growing system suppliers is often poor due to their background being the supply of soil-based system components.  Andrew believes the wealth of knowledge, in vegetable-based hydroponics, has not been sort or discovered by berry growers due to the fear of high capital costs seen in more controlled hydroponic systems.

A colleague and I sat, throughout his presentation, shaking our heads in agreement and astonishment at the basic mistakes some Australian growers are making.  It was highlighted that the Australian berry growers, venturing out of soil, are treading cautiously.  Unfortunately, their approach has the growers facing issues, such as having built substandard structures with poor internal layouts, poor water quality and delivery systems, and a total lack of technical advice from experienced consultants.  The problems there experiencing may appear standard to many that have been growing in high tech greenhouses.

Andrew’s presentation focused on light, water and substrates.  I believe you will have a much better opportunity of achieving success, switching from outdoor to indoor berry production, if you take note of Andrew’s advice below;

 

Water

  1. Know your water chemistry (seek independent advice)
  2. Know your water quality, are you using fresh or recycled water? (have it tested for nutrient levels) Make sure elements in your water don’t attribute to drippers blocking. 
  3. Dose your nutrient, do not fertigate it. 
  4. Understand how to irrigate in a closed structure.  Collect your drain water and test to know what is happening in your substrate.
  5. Use filters and water treatment techniques commonly used in vegetable systems.

 

In Australia, where it is very hot, tunnel houses have been built to grow berries on slopes for ventilation.  The hot air rises and rushes up the tunnel houses.  Pressure compensated drippers will drain under gravity and when using precise delivery techniques will not be as effective when large slopes are involved, therefore detailed hydraulic designs are essential.

 

Light and Density

  1. In the greenhouse vegetable industry, we generally base our rows on North-South, but if you are growing strawberries using a fixed, triangle tiered gutter system, it will be shading lower rows.  Plants that are shaded will use less water, therefore if all the rows are on the same irrigation valve, every row will have different fertiliser levels and water contents. This may cause an issue, as you will need to irrigate for the driest row, causing overwatering on the shaded rows that have transpired less.  The effect over time is dramatic, rightly highlighted in this presentation.  It is disabling the ability to grow evenly. 
  2. Plant density, from outdoor soil growing to soil less covered cropping is different. This will affect irrigation layouts dramatically.  Receiving the correct independent advice for your situation is paramount.

 

Substrates

  1. Many growers are using coir substrates but not all coir’s are the same so it is important to make sure you are matching up volumes and chip size needed for your particular crop, and staying with trusted and recognised suppliers to eliminate unwanted surprises.
  2. Australian berry growers are not yet using stone-wool products as their knowledge and understanding of how to use these products is limited.
  3. Using white plastic instead of black plastic on the bags/buckets is important for reducing root temperatures.

 

I strongly recommend if you are thinking of growing berries in greenhouses you use a consultant like Andrew.  To learn more about Andrew’s presentation or his consultancy services email: andrew@myriadint.com.au or check out his website www.myriadint.com.au

Industry Profile

Mike Saklani, Tomato Grower

Mike Saklani, Tomato Grower

From working for multinational companies to running his own successful businesses.

 

Mike Saklani was born and raised in Chamoli, a northern region of India, close to the Himalayas.  He was educated at an Irish Catholic School called Saint Joseph’s Academy, Dehradun, which he attended from the age of five until he was eighteen.  He then went to complete his BSC in Environmental Science at the University of Delhi and then pursued his MBA with majors in Marketing to achieve Post Graduate Honours.

He was employed by the multinational company HJ Heinz after stepping out of University, where he managed the sales and distribution network, for the western parts of India.  Mike worked there for three and half years until he was twenty-six years old.  In 2001 Mike decided he wanted to travel and have an overseas experience.  New Zealand was his option so he obtained a two-year work visa and left India.  Mike got a job ‘flipping burgers’ at a Wendy’s Restaurant in Greenlane.  It did not take long for him to climb the ladder at Wendy’s.  Mike loved New Zealand. He applied for residency and after a short time he became General Manager at Wendy’s Manukau branch, in charge of 55 staff.  After six years working at Wendy’s Mike decided he wanted to run his own business. He established a commercial cleaning business employing ten people which he had for almost a decade. 

Throughout his time at Wendy’s Mike always thought one day he would like to be a grower.  Growing had been part of his upbringing as his father has a PHD in Horticulture.  With his father’s support, Mike decided to purchase a second business growing tomatoes in South Auckland in 2011.  The property had two quite old greenhouses with no heating system.  He began growing on a total area of 1700m2.  Mike spent the first three years learning the ‘ins and outs’ of growing tomatoes.  During 2014 Mike built a 1400 m2 new greenhouse fully equipped with a new heating and pipe rail system.   He quickly appreciated the need for a good quality heating system.  The older greenhouses are better suited to shorter eight-month crops, which are planted with tomatoes in January and removed in August. They are then planted with flat beans from September to January to complete the cycle.  This year the decision was made to purchase the neighbours older glasshouses which have had their glass removed and retrofitted with plastic.   Mike joined the heating system set up from his existing glasshouse to the new property.  The heating pipes are externally insulated, reducing any loss of energy between the two properties.  His total growing area is now over 4700m2. Having five growing areas has its challenges but has the advantage of being able to grow different crops if desired.

 

Mike imported all materials for insulation of the external transport lines.

 

Few years back, Mike sold his commercial cleaning business to concentrate on expanding his greenhouse growing operation.  Mike has adapted to growing very quickly.  He believes understanding that light and temperature is your limiting factor in growing in New Zealand and addressing that will go a long way to increasing productivity and profits, “making sure you have a good heating system is crucial”

Mike is very positive about the future of growing and the increased demand for food, “There are so many mouths to feed, we need more growers”.  However, like most greenhouse businesses there are issues which are constantly making it hard to grow his business: “Labour is a major concern as it is so hard to find kiwis who want to work in hot greenhouses, especially in the summer.   It is very hard to employ foreign students who can work part time as they are being discouraged to come to New Zealand because of government policies”.  Mike would like to see incentives offered by the government to help growers access new technology.  Mike thinks for smaller growers to continue to be successful they need to spend more on capital investment to improve productivity.   Mike is interested in helping other growers and would like to become more involved with TomatoesNZ.

In his spare time Mike likes watching sport, especially cricket and football and is very interested in this year football world cup.  Mike also likes trekking and last year went to Nepal for hiking. Mike also does community work and has been part of Uttarakhand Association of New Zealand Inc (UANZ), a charitable trust, which has raised money for Starship Hospital. He was Secretary on the Board of UANZ for 3 years and organised four big musical events, with Folk Artists from the Himalayan Region. Mike is Married with two sons and enjoys quality time with his family at their home in Karaka, South Auckland. 

This is yet another story of a hardworking, well-educated immigrant who is making every post a winner and proof that there is still ample room for smaller growers to be successful in this industry.  We need more growers like Mike who are not just investing in themselves but our industry and economy.  Well done Mike.

 

In 2014 Mike built this heating system which now serves all of the five greenhouses. 

This is one of the recently retrofitted greenhouses.

 

Mike loves being a grower and the challenges it brings.  Here he is with his very strong winter crop of large loose tomatoes.
