It should also decrease N 2 O gas emissions and nitrate leaching from agricultural land, creating a healthier global nitrogen cycle.

This document helps agricultural producers understand how N interacts in the environment through the N cycle to guide maintenance and sustainability of agricultural crop production. The Nitrogen Cycle ...
