Best Management Practices for Agricultural Nitrogen Management

Comprehensive guide for Colorado producers focusing BMPs for nitrogen management for agronomic efficiency while protecting water quality.

Nitrogen (N) is the essential plant element that most frequently limits crop production. Commercial N fertilizers, manure and compost, are a cost effective means of supplementing soil supplied N for plant growth and are typically necessary for sustaining high crop yields. However, it has been documented that improper or excessive use of N sources can lead to nitrate pollution of ground or surface water. Both urban and rural fertilizer applicators can minimize this problem by implementing Best Management Practices (BMPs) for N use.
