Getting to Carbon Positive

Wednesday 21 – Thursday 22 May
Havelock North Function Centre

In 2025 we’re delighted to bring you a conference with focuses on regenerative crop production, carbon footprinting, and electrification. We’ll have new technologies to think about and see, we have speakers with proven track records, and we’re looking forward to catching up with old friends and new.

Do we know the footprint of our activities? How do international markets assess them and what will we need to report? We are proud to present Associate Professor Dr Pii-Tuulia Nikula to open the conversation. We’ve done the numbers on our Carbon Positive cropping treatments, and we’ve others talking about what they are doing to address their footprints too.

If we are going to get to Carbon Zero (or better) we need to think about both inputs and outputs from our systems. Can we soak up more than we lose? Which inputs have the greatest impact?

We’ll report on progress and lessons from another year of our regenerative cropping research and on cover cropping and bio-strips. We will present some new tools for growers to assess nitrate levels, soil stability and insect pressure and have examples for viewing at the Horizons Regional Council Field Session.

We’ll need energy, of course, but how much can we generate on-site? Is electrification realistic now? Where to in the short to medium term? We are delighted to have Mike Casey of the Electric Cherry Orchard and CEO of Rewiring Aotearoa opening that discussion. We’ll have electric vehicles for perusal.

Thanks to our Sponsors!

We look forward to seeing many of you again in 2025.

LandWISE 2025 Getting to Carbon Positive

Doing what we can to reduce our greenhouse gas emissions is not about meeting regulations, it is about meeting the expectations of our markets and others in our supply chains (and ourselves and the planet!). Most large companies must report on their own emissions and those of their suppliers and clients. We are part of their emissions profiles, and they want us to do our part.

What is it all about? What emissions are we talking about? Who is implementing changes to lower their impact? How do we start?

At LandWISE 2025: Getting to Carbon Positive, you’ll get these answers and more. You’ll hear and see examples, and hear that people are reaping benefits, because it isn’t all about adding costs, it can save money. And in another session, you’ll hear how it can even provide an alternative income stream.

The Greenhouse Gas (GHG) Protocol applies the measurement of emissions across three scopes. These are Scope 1, which includes the direct emissions from sources that the organisation owns or controls, such as fuel use for farm-owned vehicles, natural gas used for heating buildings and greenhouses, fertilizer use, leaks in refrigeration and cooling processes, as well as emissions from soil management. Scope 2 includes indirect emissions from purchased energy. Scope 3 includes all other indirect emissions in the organisation’s value chain, such as emissions from freight/transportation of products, business travel, waste, and emissions from purchased goods and services.

Pii-Tuulia Nikula (PhD)

Greenhouse Gas Accounting: Scopes Solutions Target Setting

Pii-Tuulia Nikula is an Associate Professor in the School of Business at the Eastern Institute of Technology (Hawke’s Bay), where she teaches courses on Sustainable Organisations and Research Methods. Her research has explored emission trajectories and climate disclosures of New Zealand businesses. Pii-Tuulia will cover key questions that apply to the application of the GHG Protocol, such as common issues and challenges with data collection and practical solutions available for emissions reduction across all three scopes. Finally, she will discuss how organisations can use their emissions baseline to start thinking about their emissions reduction targets.

Dan Bloomer (PhD)

Carbon Positive progress – relative footprints

Dan Bloomer is the LandWISE Manager and an independent consultant. He brings a diverse set of interests and extensive experience in field trials and extension to his role overseeing the LandWISE research portfolio. Together with Olivia Webster, he will present a study comparing the emissions from the three farm systems that form the Carbon Positive trial. What are the main drivers of emissions in an intensive process cropping scenraio?

Of course, knowing our emissions is only a starting point. We also want to know how we can minimise them. And that is the subject of the Electrification and Alternative energy case studies sessions!

LandWISE Project Manager Alex Dickson discusses some of her thoughts on Regenerative Agriculture after her trip to Europe in June.

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?

Presented by Dr Charles ‘Merf’ Merfield.

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!

Cost is NZ$391.30 excl. GST = $450.00 incl. GST.

The post Rebuilding Our Soils – Successful Conference appeared first on LandWISE - Promoting sustainable land management.

Presentations at the LandWISE Conference “Rebuilding Our Soils”

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!

Gisborne Workshop

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.

The post Soil Recovery after Cyclone Gabrielle appeared first on LandWISE - Promoting sustainable land management.

Following our successful annual conference in May, we wish to thank all the speakers and sponsors who supported us, and the delegates who enriched proceedings and made it an enjoyable event.

The conference focused on building and rebuilding our soils, topics close to recovery from the impacts of Cyclone Gabrielle and “Carbon Positive”, our new regenerative process crop production project.

The well-loved Tech Session had new companies presenting their technologies, ideas about responsible robotics and a panel discussion led by Brendan O’Connell from AgritechNZ.

Thanks Callum Ross from Ross-AI, Hamish Penny from Croptide, Quinn Elstone from WaterForce, Callum Eastwood from DairyNZ, Andrew Kersley from Smart Machine Co and Guy Coleman from University of Sydney for sharing your stories and insights!

Day 2 focused on weed management, with insights from two overseas experts, Lynn Sosnoskie and Michael Widderick, and updates from the AgResearch herbicide resistance management project – Trevor James, Zachary Ngow, Andrew Griffiths and Dan Bloomer.

The afternoon field event was a chance to see things first-hand in the paddock, and for many a first opportunity to see our regen project at the MicroFarm.

Thanks Tobi and Robert of live2give for the mulch planter demo, Hamish Penny for showing the Croptide system, Andrew Kersley and Rob Elstone for bringing the electric OXIN robot for everyone to play with, Nick Gillot of Tulloch Farm Machinery from bringing the Einbock Pneumaticstar, Andy Lysaght for demonstrating the new soil spader, Steven Haswell of BioAg for showing the germinating seed mix intended for revegetating sediment covered sites, and our own Alex Dickson for presenting the Carbon Positive winter cover crops.

Havelock North Function Centre

24-25 May 2023

It has been two years since we gathered for the last LandWISE Conference. We were unsure in 2022 what Covid was doing and chose to not add to its possible spread. With that more controlled if not fully behind us, we were feeling hopeful of a return to normality. But. . .

We’ve had the wettest time in memory in Hawke’s Bay, and Tairawhiti and Northland feel the same. A wet winter, a horrible spring, and then summer: notably Cyclone Hale and the big slapper, Cyclone Gabrielle. Plans have been tossed in the air, churned by the river, and dumped unceremoniously in the bottom of the orchard. So now we wonder what to expect. What is the future normal?

Three key topics feature at LandWISE 23. We wrap up the five-year Herbicide Resistance Management project led by Trevor James. We introduce a new six-year project partnership with the HB Future Farming Trust investigating regenerative farming from an intensive process cropping perspective, and we consider how cropping farmers and growers are responding to flood inundation following Cyclone Gabrielle – in some cases maybe “generative farming” if deep deposits need to be turned into good quality land with a well-structured topsoil.

And tech stuff!
