A simple tool for evaluating Nitrogen Use Efficiency improvement technologies

This tool was developed to analyze the impact of adopting NUE improvement technologies on nitrogen fertilizer application rates, nitrogen use efficiency, and farmer’s profit on farm and regional scales, assuming the farmer optimizes nitrogen application rates to maximize profit.

Optimal nitrogen fertilization rates and net profit for different technologies, under various fertilizer-to-crop price ratios.
