Reflecting this connection to nature,…
Soil Health for Profit
LandWISE Conference 2026 Havelock North Function Centre27 – 28 May 2026 Our “Soil Health for Profit” theme in 2026 is, in some ways, a return to the past. LandWISE arose out of work to combat soil erosion through use of minimum tillage and we’re returning to strip-till in 2026. A lot has been learned in…
Winter Cover Crops
After the 2025-2026 butternut crop was harvested, the Regenerative treatment received Omya Calciprills (150 kg/ha), Sulphur (30 kg/ha), Boron (10 kg/ha), and Humates (5 kg/ha). This mix has been applied annually to stimulate soil microbes for good soil health. Thanks to Websters Hydrated Lime for supplying the micronutrients again. All three treatments were then disced…
Butternut Harvest Data
Heniz-Wattie’s was unable to process our butternut through the factory due to a lack of demand, so we had to find an alternative outlet. A local grower ended up harvesting the butternuts on the 13th of March, which was a month earlier than our target harvest date with Heniz- Wattie’s. Our butternut hand harvest of…
Butternut Harvest
Our butternut hand harvesting to collect research data was completed on the 9th and 10th of March. Our hand harvest samples were taken from 3 m × 2 m areas within each of the four subplots of each plot; 16 per treatment, 48 in all. All butternuts within the sample area were cut from 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…
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 Accounting in Carbon Positive
One way to track greenhouse gas emissions is through carbon accounting. Carbon accounting quantifies carbon dioxide, methane, and nitrous oxide emissions. We have been tracking the relative emissions from each of the three different management systems applied in our Carbon Positive trial. There are three scopes within carbon accounting: Scope 1, Scope 2 and Scope…
