N predictor pleases

USING the MGAs nitrogen predictor service lowered some members fertiliser costs and on others recommended double the amount.

MGA member Norman Light said one farm saved 63-88kg/ha (50-70 units/acre) of nitrogen and although crops did not look as green to begin with, they cobbed up well. Doubling fertiliser use on another farm allowed the maize acreage to be cut because of higher yields.
