Abstract

What is the potential payoff for farmers moving from traditional whole-field management or integrated crop management to precision farming? Using computer models, the investigators sought to analyze how inputs can be applied at optimal rates variably across a field in order to match inputs with crop needs. Over the long term, only modest increases were shown in gross returns from these practices. However, gross returns for individual years can be substantial.
