Evaluating variable rate fertiliser application. Neil and Michelle Walpole Archive Trial

Background

Neil has been utilising variable rate application technology for about 3 years. Initially, Neil applied variable rate lime on his fallow blocks, using EC Mapping and targeted soil sampling to guide the applications. It was a natural progression for Neil to move to variable rate application of fertilisers, initially targeting blocks where high sodium levels severely impacted yield.

Neil has established a new trial to evaluate the performance and economics of variable rate fertiliser application on fields where the yield variability is more modest.
