Summit’s In-Season Nitrogen Calculator aimed to calculate a precise N rate to maximize yield potential of a paddock where a crop is starting to run into N limitations, using NDVI as a real-time growth measurement. It was designed to utilise comparisons between crop growth without N limitations beside paddock practice to determine optimal N application for yield and returns.
In 2016 DAFWA, in collaboration with the WMG, established three claying trials in the region looking at combinations of different clay rates and incorporation methods using a range of tillage equipment. The aim of the trials was to identify the most cost-effective combination/s and produce practical guidelines for farmers seeking long term improvement for enhanced crop productivity on water repellent soils under local growing conditions.
