Lessons for the management of highly productive land Two years after Cyclone Gabrielle devastated the Hawke’s Bay and Tairawhiti regions, what have we learned about recovery? Cyclone Gabrielle struck New Zealand in February 2023, causing widespread flooding that affected Hawke’s Bay, Gisborne/Tairawhiti, and Northland. In Hawke’s Bay and Tairawhiti, Cyclone Gabrielle was characterised by the…

Carbon Positive: Butternut Planting to Side Dressing
Planting The butternuts in the Carbon Positive trial were planted on the 15th of November. Before the butternuts emerged, there was a high weed pressure in the conventional treatment. Therefore, it was sprayed with Buster, while the other two treatments were not. Emergence When the butternuts started to emerge, we noticed there was cutworm damage…
Nitrate Levels on the MicroFarm
Throughout the Carbon Positive Trial, Soil Nitrate levels down to 30cm have been monitored fortnightly. During the tomato crop (26/10/2023 – 6/3/2024), the Regenerative treatment had significantly lower nitrate levels than the Conventional and Hybrid treatments, despite all three receiving similar amounts of nitrogen. This lower nitrate level was likely due to the breakdown…
Cyclone Gabrielle Research Symposium
Lessons for the management of highly productive land In November, we co-hosted a research symposium with Vegetable Research and Innovation and the Foundation for Arable Research. The symposium brought together those who had investigated Cyclone Gabrielle’s impacts on highly productive land to present and discuss findings and observations, and draw out lessons to aid land…
Carbon Positive: Butternut Planting
The butternuts for our 2025-2026 cropping season, in the Carbon Positive trial, have been planted! The Conventional treatment was planted with treated seed and 300kg/ha of Complex fertiliser. The Hybrid treatment was planted with treated seed, coated in TrichoStart and 300kg/ha of Complex fertiliser. Mycorrcin, Biostart N and TrichoStart were applied at planting via liquid…
Carbon Positive Soil Monitoring
All Systems Stable: Early Insights from a Crop-Driven Carbon Cycle Carbon Positive is, unsurprisingly, tracking soil carbon levels under our three different management approaches. We have two key measurements; total soil carbon and hot water extractable carbon. Hot water extractable carbon is a laboratory test measure of labile carbon, which is the ‘active’ carbon that…
Farmer Friendly Nitrate Testing
Validation and Practical Implementation of the Nitrachek 404 Have you tried to match soil test strip colours against the colours on the tin, and found yourself wondering if you’re seeing the right shade of purple? Those days of guesswork can be over. The Nitrachek 404 is like having a portable lab right in your paddock….
Cover Crops Survey
With funding from Te Ahikawariki, we teamed up with regional agronomists to ask a number of growers about cover cropping. We wanted to learn what the barriers were to new entrants, and what the ongoing headaches were for those who do use cover crops. Three-quarters of the 32 growers surveyed have been using cover crops…
LandWISE Conference Summary – Day 1
The LandWISE Conference, Getting to Carbon Positive, attracted more than 80 people who heard speakers on a wide range of topics related to ongoing sustainability. Day 1 discussed ways to assess our emissions levels, how we can reduce our environmental impact through diverse farming techniques including regenerative practices and soil health, and new research around…
LandWISE Conference Summary – Day 2
The LandWISE Conference, Getting to Carbon Positive, attracted more than 80 people who heard speakers on a wide range of topics related to ongoing sustainability. Day 2 had a strong focus on electrification options to increase profitability and reduce emissions. New Zealand is reaching a point where solar power is the cheapest energy available –…
