Summary edit

Excess nitrogen per hectare
Title
Excess nitrogen per hectare
Description
Excess nitrogen per hectare of cropland. "Excess nitrogen" is the difference between nutrient inputs (from fertilizers, manure, and fixation from legumes) and the amount harvested in crop material. This represents nitrogen that is lost to the environment and can create ecological imbalances in ecosystems and water bodies.
