WHY SHOULD i BE CONCERNED?
Animal manure can be a valuable nutrient source and soil conditioner. When managed properly, the nutrients in manure can be substituted for commercial fertilizers, saving money and protecting both ground water and surface water. Matching nutrient applications to crop nutrient needs is critical.
Runoff from improperly stored or managed manure can lead to contamination of groundwater and surface water. Land application of manure at proper agronomic rates or composting of manure conserves nutrients contained in the manure and minimizes leaching and runoff of contaminants. Manure storage in an appropriate structure increases a producer's flexibility regarding the timing of land applications. Storage is also valuable during extended periods of bad weather and when crops are actively growing, making application impractical.
Proper management of stored manure depends on proper design and construction of the storage facility, a good knowledge of the physical and chemical characteristics of the soil and subsurface geologic materials within the storage area, and proper land application of manure once it leaves the storage facility.
