Nutrient Management

The most widely used method of reducing manure is land application. Not only does this reduce the amount of manure (solid or liquid) that is stored onsite, but it can also make the soil more productive. Organic matter, such as manure, can increase nutrient values of the soil. It can also improve soil structure, which leads to increased infiltration and less leaching of irrigation water. However, if the manure is applied improperly, it can become a potential pollutant. Therefore, we have developed this page to help you understand more about nutrient management.
