Nitrogen requirements and usage vary across maize, wheat and rice systems in Ethiopia, Malawi and India. Analysis of these systems indicates that targeted nutrient management strategies could increase the efficiency of nitrogen usage, helping to address fertilizer shortages and reduce the negative environmental impacts of excess nitrogen.
