Issue 5 - Nitrogen in Perennial Ryegrass Seed Crops

With Spark and One NZ decommissioning their 2G and 3G networks across the country near the end of 2025. FAR has contacted the companies involved with the moisture probe trial to find out how it could affect your farm.

This FAR Focus outlines the key practices required to grow cocksfoot seed crops, covering topics such as crop establishment, nutrient requirements, crop management and harvesting. Topics outside the scope of this booklet include emissions profiles and off-farm considerations such as seed cleaning etc.

This update outlines the results of five years of trials exploring pre-desiccant options for managing bulky white clover crops, aiming to reduce rapid leaf regrowth following diquat desiccation under wet or high-fertility conditions. Achieving effective desiccation required balancing this process with post-harvest regrowth, as clover seed crops are often used for lamb grazing on New Zealand cropping farms.

FAR's technology manager Chris Smith gives you some tips and tricks to help you pick the best moisture sensor for your system.

In 2023, FAR set up a Moisture Monitoring project at its Kowhai Research Site in Lincoln to provide independent insights into the range of moisture monitoring systems available in New Zealand. This report covers findings from the first year of the trial and outlines key considerations when choosing a moisture monitoring system.

Pure Oil NZ and FAR are collaborating to monitor oilseed rape (OSR) paddocks to identify strategies to improve yields. Their work has identified that many growers could reduce the amount of nitrogen applied to OSR crops without impacting on yield or profit.

This Arable Extra discusses optimal nitrogen rates for crops based on 2024-25 fertiliser and crop prices.
