Cyclone Gabrielle Research Symposium
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…
Biodiversity Strips Update
We established two new biodiversity strips on the MicroFarm in 2025, in addition to the two from 2024. One of the new strips, which is located under the irrigator wire, includes alyssum, calendula, and native ground covers. The other strip which is along a fenceline has the A Lighter Touch annual flower strip mix, which includes alyssum,…
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…
Looking Ahead: Butternut squash
In the 2025-2026 cropping season, the fourth summer of the Carbon Positive trial, we are growing butternut pumpkins for Heinz-Wattie’s. Our planned planting date is the middle of November. In the Conventional system, things are getting underway with a broadcast spray of glyphosate now that the sheep have been moved out. The paddock will be…
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…
Carbon Positive: Winter Cover Crops
The cover crops were direct drilled by Kettle Contracting on the 7th of April. The Conventional treatment was planted with Moata annual ryegrass. The Hybrid treatment also has Moata with crimson and Balansa clover added. The Regenerative treatment has the same cover crop mix as the Hybrid treatment with the addition of vetch. As in…
