Integrated plant nutrient management

Definition

This represents the inverse of values in the agricultural Sustainable Nitrogen Management Index, which combines data on nitrogen use efficiency and land use efficiency (crop yield) to provide a measure of the environmental efficiency of agricultural production.

Relevance

Sustainable production depends on nitrogen management. Nitrogen inputs are important for improving low crop yields; however, intensive crop systems mine nutrients from the soil, which if not recovered, will degrade soil fertility and lower long-term crop yields.
