To investigate the effect of variable rate nutrient applications based upon zone crop yield potential
This project will build on previous Catalyst trials that have shown there is the potential to improve nitrogen use efficiency without compromising yield by reducing Nitrogen rates in zones with low cane yield potential.
Through analysis of archived satellite yield data over the previous 16 years, it is possible to identify the locations of potential low yield zones at an intra-paddock scale.
Being able to accurately identify these zones has previously been an impediment to the adoption of Precision Agriculture practices. Using this approach on a paddock scale will assist in validating the process and then measuring the effect of variable rate nutrient applications based on the analysis of the historical yield data.
