1. Land Application of Manure

Manure is a valuable nutrient source for agronomic crops that can replace commercial fertilizers if applied at the appropriate rate. Manure has additional benefits because the organic matter added to soils increases microbial activity, enhances soil tilth and nutrient and water holding capacity. The result can be increased crop yields and reduced erosion.
Manure, when applied at the appropriate rate and in a manner that prevents runoff, is environmentally safe. However, if it is applied at rates greater than crops can use or if it is allowed to run off the field, it can be a pollution hazard to either ground or surface water.
