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!
