Optimal nutrition packages for renovated cemented lateritic gravels to increase farm profitability

This investment aims to boost grower and adviser confidence in nutrition decisions on renovated cemented gravel soils. This will be achieved through successful extension of the outcomes of an initial comprehensive soil testing survey, followed by a series of farm scale nutrition trials and finally through an economic analysis of time to return on investment which factors in the cost of renovation and the yield benefits of differing fertiliser regimes.
