Two suggested approaches for increasing biodiversity caught our attention. Over the last six months, we have been exploring their implementation at the MicroFarm. We are enormously grateful to Olivia Prouse for supporting our biodiversity journey so far. We are also grateful to Richard Mills from Summerfruit NZ for leading the way in Hawke’s Bay, and showing us the importance of just giving something a go! We also extend our gratitude to other growers engaging in this initiative, who have been sharing their experiences.

Mobile Insectaries

Mobile insectaries (moveable pods) aim to provide a source of shelter, nectar, alternative hosts and pollen (SNAP) for beneficial insects. The concentrated areas of SNAP support natural enemies, which can aid in pest control in vegetable crops. The moveable pods can be moved in and out of crops easily during the year.

Following the detailed ‘how to’ guide provided by ALT, with additional support from Olivia Prouse for plant selection, we built four moveable pods. Each pod has native five plants, all selected to flower at different times of the year. The species selected were mainly plants that had small flowers to provide habitat to small predatory wasps and other small insects which cannot feed on large flowers like commonly grown manuka.

We have been monitoring the pods to see what is flowering each month. While there is some maintenance required for weeding and watering, all plants survived the winter and are thriving this spring. We are excited to have species like Pimelea mimosa, which is a native daphne, naturally found only on Te Mata peak, and to have two species of Muehlenbeckia, which provides a food source for NZ native copper butterfly.

Annual Flower Strips

The aim adding annual flowering strips to a farm is to enhance above ground diversity. Again, this increases the diversity of natural pest insect enemies, providing additional pest control.

At the MicroFarm, we had two specific areas that made for good candidates for annual planting strips. The first is along our driveway, an area which is normally sprayed year-round for weeds. The second is under the irrigator guide cable, another area that gets sprayed, particularly in the spring and summer when the irrigator is running.

Using the ‘how to’ guide from ALT, we have planted a variety of annual flowers in these areas to see what might be suitable. In late September, we planted nine 10 m long plots of annual flowers, each with different combinations of species planted. The rest will planted by early December. We have been monitoring what is growing and what is flowering, and are excited to see insects present and a range of different colored flowers along the driveway.

What’s next?

We continue to monitor the moveable pods and annual flowering strips. We hope that our late plantings will persist through the summer and autumn. While not formally part of our main Carbon Positive project, it is a nice supplementary demonstration. We hope to showcase the ALT guides and provide some regional information about what may be suitable to grow (annuals and perennials) here in Hawke’s Bay.

The current approach to assessing earthworms is through field visual assessments, which can be labour intensive and requires expert knowledge in identifying species. The new test provides a convenient and efficient alternative for earthworm testing.

The soil test has been calibrated for 7.5 cm soil depth in pastoral settings, rather than the 15 cm depth which is the standard depth for horticultural and arable soil tests.

We have been working with Dr Nicole Schon at AgResearch, who helped to develop the test, and Hill Laboratories to better understand how the test might be relevant within a cropping context.

This month, we completed our six-monthly Visual Soil Assessments in the Carbon Positive plots. As part of this process we sent all earthworms found to Nicole for identification, and soil samples to Hills to test for A. caliginosa eDNA. We hope that these samples will help to strengthen the understanding of the soil test taken to 15 cm depth.

Check out Alex and Nicole’s article in the latest NZ Grower magazine (pg. 48-50) for more discussion, or the Hills technical note for more details.

In June this year, I was chosen for one of two teams attending the 2024 International Food and Agribusiness Management Association (IFAMA) Case Study Competition and Conference in Almeria, Spain. The theme of the conference was Food Security Through Innovation & Sustainability. We were then invited to attend a weeklong food and agri-innovation tour to Bologna, Cologne and then through the Netherlands.

I am lucky to have been in a team with four clever individuals from across the New Zealand Agri-Food sector. Our team included Dan from Silver Fern Farms in Dunedin, Fatima from ANZ in Auckland, Braydon from Perrin Ag in Rotorua, and Katie from Auckland University. We brought a diverse range of skills to our case study analysis, as well as a diverse range of opinions and perspectives on agriculture.

We were incredibly excited to learn that we won first place in our division, with the other New Zealand team coming in second place. Not bad for a little country at the bottom of the world!

While travelling together after the conference we were able to explore food provenance and food culture in Bologna, agricultural research and development in Cologne, and agricultural and horticultural innovation in the Netherlands. We will all be spending the next few months digesting what we have seen, discussed and learnt, and how our experience links to food production back here in New Zealand.

Many thanks to LandWISE (Dan & Phillipa) for allowing me the time away to learn, grow and explore the agri-food sector at a global level.

Almería – a sea of greenhouses

At the bottom of Spain on the edge of the Mediterranean Sea, you’ll find Almería. Almería is a city and municipality of Andalusia, and is located in the desert, receiving only 200 mm of rain per year. Despite this, the region is a hub of horticultural production, with 32,200 ha of greenhouses spread across the landscape (3.7% of the total area of the province), as well as around 30,000 of open-air production.

There are 12,500 farms with undercover production which generate more than 110,000 jobs. There are many small growers who are represented by grower co-operatives. In fact, there are enough co-operatives that secondary co-operatives exists which are ‘co-operatives of co-operatives’, for example Unica, which represents 15 co-operatives. The industry prides itself on being leaders in tech transfer to growers of all sizes, and strives for shared wealth creation, and keeping small farmers in business.

The annual turnover in the region is €4.4 billion, plus an additional €1.5 billion from the auxiliary industries including nurseries, R&D centers and suppliers (approx. €6 billion total per year). Given the region’s warm location, growers can achieve year-round production. The main crops grown are eggplants, zucchini, cucumber, tomato, pepper, melon, watermelon and lettuce. In total, 3.7 million tons of fruit and vegetables are produced each year. The first greenhouse was built in 1963 and since then has taken the province from one of the poorest in Andalusia to one of the wealthiest, now ranking above average in Spain.

In 2007 a program was started to implement biological controls in horticultural crops to produce residue free crops. In 2023, Almería had the largest area in the world using biological controls in vegetables, totaling 26,800ha.

Challenges

There are significant challenges to producing food in such an intensive way, and there has been much criticism of the region’s intensive production methods and the impact on the environment.

Water is unsurprisingly a key issue in a desert. Historically water has been extracted from groundwater, depleting underground aquifers. In recent years, desalination plants have been built to provide fresh water through reverse osmosis for both human consumption and irrigation, although water is still having to be extracted from the ground to meet demand.

Plastic use is also a challenge, with the plastic on the greenhouses being replaced by growers every 3 years, however the industry reports that 100% of the plastic is recycled.

The source of the region’s labour supply has faced criticism in recent years, in relation to the exploitation of migrant workers working in the greenhouses.

Netherlands- home of the modern glasshouse

As part of our trip, we travelled through The Netherlands, where we had the opportunity to visit Van der Harg in Bemmel. They grow and pack capsicums/bell pepper in their 8.6 ha of glasshouses. They are also experimenting with growing eggplants. The design of the Dutch glasshouse originated in Den Hague, and there are 10,000 ha of glasshouses in The Netherlands today, which largely grow bell pepper, eggplant, tomato and cucumbers.

The seedlings are grown at an independent nursery and planted into the glasshouse in November. The first fruit is harvested in February. Production lasts until October when the plants are pulled out and the greenhouse is prepared for the next crop. Interestingly, the crop is grown with few to no sprays, however the crop cannot be classified as organic as it is not grown directly in the soil. The plants are grown in ‘cultivation gutters’, where there are understory plantings which are used for pest control, and climate control.

The glasshouse is located in an Agropark, NextGarden, which allows participating growers to reduce their costs by ‘industrial symbiosis’; sharing resources and infrastructure. This includes collective power generation and a biodigester. By-products of the biodigester are captured (heat and CO2) and used by the glasshouses. There is also collective water harvesting systems that delivers clean rainwater for irrigation and processing.

Challenges

There are of course challenges to this system. The process of harvesting is labour intensive, with the labour supply coming from largely from countries like Romania. A robotic harvester has been developed, however must harvest ’27 hours a day’ to be the same cost as a human. Once they reach 24 hours, the human element of production will largely be gone.

Additionally, the strings used for training the capsicum plants are plastic. To maintain production levels they are not able to use biodegradable strings as they are not transparent enough and block too much light. The plastic string is used for just one season and is the major waste product of the system.

This system is energy intensive, particularly in heating over the winter months. However, Van der Harg are working with NextGarden Agropark to reduce or capture emissions, to power the glasshouse in a sustainable way.

Same challenges, different growing system

Regardless of growing system or location, the same conversations are happening globally, in relation to the challenges growers face. Water, energy, ethical labour supply, agrichemical use, and plastics are issues facing farmers and growers regardless of system or size.

The post European Covered Production appeared first on LandWISE - Promoting sustainable land management.

As I grapple with my own understanding of Regenerative Agriculture (RA), a trip to Europe was just the thing I needed to provide me with more questions than answers!

1. What are the right policy tools to support both sustainable food production and growers making a livelihood?
2. How does RA scale to go beyond a ‘buzz word’ to have a meaningful impact on the environment?
3. What role do large corporations play in the transition to Regen Ag?

EU Green Deal- Farm to Fork Policy

In 2020 the European Union introduced the Farm to Fork (FTF) policy as part of the EU Green Deal. The policy aims to rethink the whole food value chain, minimise the environmental impact of food production, improve resource efficiency and enhance biodiversity.

Targets set by the FTF include:

• 50% reduction in the use and risk of chemical pesticides by 2030
• 50% reduction in nutrient losses, while ensuring no deterioration in soil fertility by 2030
• 20% reduction in fertiliser use by 2030
• 50% reduction in the sales of antimicrobials for farmed animals and aquaculture by 2030
• 25% of total farmland to be farmed organically by 2030 (9.9% of farmed area was under organic farming in 2021).

These are ambitious targets. In response to these targets, European businesses of all sizes are having to rethink what ‘the system’ looks like in the future and how they fit into food production not only in the face of environmental policy like the FTF, but also in a changing natural environment.

“Regenerative practices are for the future, not for today”

A quote by Tony Salas (founder of Shared X, Peru) at the 2024 IFAMA Conference in a session dedicated to discussing the future Regenerative Agriculture. Shifting from conventional growing methods to regenerative methods shifts the focus from yield, to the management of a functional ecosystem with an emphasis on healthy soils.

Salas reflected on the challenges that the Organic Agricultural movement has had in scaling globally, in 2021 only about 1.6% of total agricultural land was managed organically, and in global food sales organic produce accounted for 1-2%. Such challenges include regulatory barriers, reduced yields, market and distribution challenges and lower profitability.

So what should the regenerative system approach be? How do we scale RA to improve ecosystem and soil health, AND ALSO feed a growing global population, meet increasingly stringent regulatory targets and provide farmers and growers with a good income? Three key points stood out;

1. Focus on adopting a continuous improvement model (Plan>Do>Check>Act) at all stages of the food-value chain
2. Develop flexible standards and avoid exclusive certification
3. Actions must be underpinned with a focus of minimising agricultures contribution to climate change.

“From ‘producing more with less’ to ‘producing more and restoring more’.”

A comment from Kai Wirtz from Bayer, one of the worlds largest agri-chemical companies. Bayer are putting Regenerative Agriculture (RA) at the heart of their company, with a vision to restore nature, and scale regenerative agriculture. They believe that it is possible to grow more using regenerative practices. Their sustainability commitments include reducing GHG emissions per kilogram of crop by 30%, reducing the environmental impact of crop protection by 30%, and supporting 100 million smallholder farms in low and middle-income countries.

Bayer has a global footprint, and they see their portfolio of products and technologies being integrated into regenerative agricultural systems, taking a multi-crop/multi-season approach to farming. This portfolio includes biologicals, crop protection, advanced seed breeding and digital tools.

“Regenerative agriculture is not a destination but a path”

I have arrived home with more questions than answers.

Europe appears to be leaning into regenerative agriculture in a big way, in response to not only stricter environmental policy, but also in what seems to be reasonably genuine concern for the future of the planet and our collective ability to feed a growing population. Large companies (like Bayer) are positioning themselves in the market to support growers in implementing regenerative practices to suit their individual farm systems in countries around the world. We see this in platforms like the Sustainable Agricultural Initiative (SAI), who have signed on over 180 global companies, with the shared goal of transforming agricultural practice for a more sustainable future.

Back in New Zealand, I wonder if we are taking regenerative agriculture serious enough? There are many unknowns, we don’t really know how RA works in NZ farm systems (though we are trying to find out) and change is scary – I find that in our own project. However, I think we know enough to have a go, to start exploring ways of improving management practice to restore ecosystem and soil health.

How do we scale regenerative agriculture in a way that we have meaningful impact on restoring the environment? How do we access the technologies being developed overseas to support change? What does the future of market access look like if we don’t adapt? What does the future of our environment look like if we don’t start to look after our soils?

Or to put it more positively, what does the future look like if we do start to look after our soils? What are the possibilities?

9:00 am to 5:00 pm, Friday 26 July 2024

PIA Event Centre, Pukekohe, New Zealand.

In person only, there is no online version.

The purpose of this workshop is to give a complete overview of non-chemical weed management as part of Integrated Weed Management (IWM) and will include addressing herbicide resistance.

Merf is head of the BHU Future Farming Centre and Merfield Agronomy Ltd and co-owner and director of PhysicalWeeding. He is also the OrganicNZ 2024 Organic Leader of the year for excellence in science communication.

The primary audience is cropping (horticulture and arable) farmers & growers as it is these production systems that have the largest challenge with weeds. Perennial crop (e.g. vines, apples) producers will also benefit with one section dedicated to perennial crops (see below). For anyone dealing with herbicide resistant weeds, this workshop is the start of your solution. There are also some benefits for livestock / pasture systems in terms of the overall concepts of non-chemical and integrated weed management.

Consultants and advisors working with farmer and grower clients, particularly in cropping, will gain considerable benefit, especially regarding the latest technologies. Scientists, especially those dealing with herbicide resistance and working on the transition to non-chemical weed management, will gain valuable insights. The content assumes a reasonable level of understanding and practical experience of commercial agriculture and horticulture systems including weed management. This is a really full on and intense workshop – bring your thinking head! Plenty of caffeine is provided!

In the summer of 2023-2024, the LandWISE MicroFarm grew process tomatoes for Heinz-Wattie’s using three alternative management systems: conventional, regenerative, and a hybrid taking from each. One of the principles for a regenerative system is to build natural resilience rather than rely only on a chemical-based crop protection regime. Nothing new, of course, we’ve had IPM programmes for decades.

How can we apply these concepts in an intensive process vegetable crop production system? What are the elements we need to consider, and how do we bring them together? There are tried and proven approaches, there are ongoing developments, and there are new ways that are being explored. Come to the LandWISE Conference “Rebuilding Our Soils” and hear what experts have to say!

Bruce Mackay, Heinz Wattie’s agricultural manager, has been an agronomist for a long time and has seen and tried different growing philosophies in a commercial context. As a key partner in Carbon Positive, Wattie’s has been deeply involved since Day Zero, and doubly so through the 2023-24 cropping season as we’ve worked to integrate regenerative agriculture principles into an intensive crop programme. Why is Kraft-Heinz interested at a global level? Why is Heinz-Wattie’s investing in local research?

Tika Schellevis started working on assessment of regen ag practices in Canada as part of her master’s degree in climate studies at Wageningen University. Over the last two years, Tika has been part of McCain Foods’ Regen Ag journey. Since October 2023, Tika has been working with the McCain Foods agronomy team in Timaru. Tike will outline how the Environmental Impact Quotient, EIQ, can help understand the relative impacts of different agrichemical options, and help select an optimal programme.

Jessica Vereijssen will discuss integrated pest management, using our crops as examples, but presenting transferable principles. She leads the Insect Dynamics, Ecology, and Sustainability team at Plant & Food Research in Lincoln. Jessica specialises in Integrated Pest Management and sustainable management programmes, considering the biology, behaviour, and ecology of pests. Her current research delves into (invasive) insect vectors such as psyllids and aphids, as well as the potential transmission of plant pathogenic organisms, leveraging her dual background in entomology and plant pathology. 

Chris Thompson will describe the use of predatory insects. He is a seasoned professional in the biotechnology industry, and Managing Director of Bioforce, where he leads the development of sustainable agricultural products and environmentally friendly solutions for various industries. When we received a “bag of bugs” to help control Tomato Potato Psyllid, he’s who we rang with twenty questions. Where do we put them? What agrichemicals might be OK? Which ones should we avoid at all costs? etc.

Since we began the Carbon positive project, we’ve been introduced to a huge range of products described variously as crop elicitors, bioactives, biostimulants, natural protectors and more. Tony Reglinski is a Senior Research Scientist at Plant and Food Research where he investigates the use of plant defence inducers to enhance natural resistance against pathogen attack. His research has covered a broad range of crops including, cereal, radiata pine, wine grapes and kiwifruit. His aim is to is to improve our understanding of the benefits and potential limitations of inducers in order to facilitate their practical implementation as crop protectants.

Come along and hear these experts as they lay out options to increase our resilience and reduce reliance on single approaches to crop protection. The principles and concepts apply broadly, so there wil be gold nuggets regardless of your crop interests!

Biological Control Agents (BCA)

In mid-December, we released biological control agents (BCA’s) into the trial area, as an alternative way of managing pest insect species. The main target is the regenerative treatment, however the nature of the species we have released, and our trial layout means it is hard to isolate to just one treatment. The three species we released are Tamarixia, Tasman Lacewing and Pirate Bugs. All BCA have been provided by Heinz-Watties, through Bioforce Ltd. 

We have applied a single insecticide to all treatments so far. We applied Benevia (cyantraniliprole), which is effective for both sucking and chewing insects in potato and tomato crops. It is most effective as a preventative measure for pest control. The main target of this spray is Tomato Potato Psyllid (TPP), but it also controls onion thrips and aphids (FMC, 2023). We have found green peach aphids in the tomatoes, as well as a few thrips and whitefly, however the incidence of these insects seems to have reduced to virtually nil after the Benevia application. Formal monitoring of leaves for pest insects and disease started the week before Christmas.

Caution is being taken not to apply insecticides that will kill the parasitic wasps, and other beneficial insects. We have been using yellow sticky traps to monitor for TPP but by 20 December we have not found psyllids in our crop.

Tamarixia triozae – Parasitic Wasp

Heinz-Watties has used Tamarixia triozae to control TPP in their tomato crops. We released Tamarixia into our four regenerative treatments before Christmas, 8 weeks after planting. The insects are delivered in small plastic vials, to be distributed into target areas.

Tamarixia (T. triozae) is a small parasitic wasp that parasitises TPP. TPP was first found in New Zealand in 2006 and has since spread throughout the country. The small flying insects impact solanaceous crops (e.g., tomatoes, potatoes, capsicum, and eggplants), and vectors a disease called Candidatus Liberibacter solanacerum (CLso) or Zebra Chip virus (Bioforce Ltd, 2023b). In tomatoes the virus causes leaf curling and yellowing, and softening of fruit, causing the fruit to be unfit for processing (Anderson & Davidson, 2020). Adult female T. triozae will lay an egg on the underside of the host insects (4^th– 5^th instar TPP nymphs), actively seeking out and targeting TPP (opposed to generalist predators that target most prey). The larvae become an adult inside the nymph and will completely ‘excavate’ the body of the TPP and will pupate inside the shell of the host. It will then chew a hole in the shell and emerge, ready to hunt more TPP (Anderson & Davidson, 2020).

Micromus tasmaniae – Predatory insect (Tasman Lacewing)

We released Tasman lacewings into the Regenerative treatment in week 8 (before Christmas). Tasman lacewings are a generalised predator and predate pest insects such as aphids, whitefly, and psyllids (all of which are found in tomato crops). Lacewings are known to be a successful predatory insect in capsicum, citrus and cucumber crops (Bioforce Ltd, 2023c). 

The insects are delivered as eggs attached to a small piece of hessian cloth. They are predatory at both the larvae and adult stages and will start to predate aphids soon after hatching. As they are released at an egg stage, moving into a larvae stage, they should be released into an area where prey is present, so they have an immediate food source (Bioforce Ltd, 2023c). Pest insect populations do appear to have been supressed from the initial Benevia application, so we do question if they will have enough to eat to start with. We hadn’t identified any particular ‘hot spots’ so we evenly distributed through the Regen treatments (8 small pieces of cloth per plot).

There are many different types of aphids in New Zealand, the most significant cause of damage is through the transmission of plant virus diseases, in tomatoes these viruses include alfalfa mosaic virus, cucumber mosaic virus (Cameron & Bourdot, 2005) and tomato yellow top virus (Bioforce Ltd, 2023a).

Orius vicinus – Predatory Insect (Pirate Bug)

Orius is a small predatory insect, and will predate a range of prey including aphids, thrips, whiteflies, and psyllids. The insect is an aggressive feeder in the lab but use of Pirate Bugs in the field is still experimental. Similar to aphids, thrips seem to mostly be under control in the trial area after the initial Benevia application.

Thrips are one of the main target species of Orius. Both adults and juveniles will attack thrips at all life stages. While thrips themselves will not generally cause economic damage to a crop, they can spread Tomato spotted wilt virus (TSWV) (Cameron & Bourdot, 2005).

The insects were delivered in a bottle of buckwheat husk media and sprinkled onto tomato leaves. It was advised to spread the insects out in the four corners of the trial area, which is what we have done (not necessarily specific to Regen treatment).

Bushmere Arms, 1:30pm Tuesday 20 June

We welcome growers and other interested people to an afternoon meeting to discuss actions growers can take to help restore paddocks impacted by Cyclone Gabielle. This meeting is open to all growers; pasture, fruit and vine crops as well as vegetable and arable crops.

Please register – it is free, but we like to be able to plan!

We all know that Gisborne and Hawke’s Bay have been severely impacted by sediment as a result of Cyclone Gabrielle. Months on, there are still many problems to resolve, of which one is “what do I do to fix my paddocks?”

LandWISE with support from MPI, Vegetables NZ, AgResearch, Massey University, Gisborne District Council and Plant & Food has been coordinating the collection of information from experts and from impacted sites. We are offering this Gisborne Workshop to share the lessons so far, offer ideas of possible management actions, and outline a proposed long-term project to continue supporting growers.

What we expect to cover:

• What information is out there?
• Learning from the past
• Decision tree to guide management choices
• Early results from Hawke’s Bay testing
• Early results from Tairawhiti testing
• Paddock responses so far – what seems to be working?
• Where to from here?

We are also working with growers in Northland who, while not covered by sediment, have been severely impacted by constant flooding and long-term soil saturation. There are similar sites in Hawke’s Bay and Tairawhiti. It has not been an easy season for anyone.
