Manure Storage and Runoff Control: Structural practices that can help protect water quality and make manure management more convenient for the farmer.
How it Works
Along with a nutrient management plan, many farmers use manure storage structures and barnyard runoff controls to improve manure management and protect water quality. Storage allows manure to be safely stockpiled until conditions are environmentally safe for spreading. Runoff controls such as diversions, rain gutters, settling basins and filter strips keep clean water from flowing over manure-covered areas and clean up runoff water before it reaches a waterway.
A diversion around an animal lot and gutters on buildings are inexpensive and effective ways to minimize the amount of water falling on and washing across manure covered areas. A diversion is often the first step in solving a runoff problem.
Incorporating a concrete wall with an outlet box at the lower end of the lotcontrols the rate of runoff to filter areas, and allows trapped manure to be easily scraped and removed. A grass filter strip cleans up water that leaves the lot.
Four types of storage are common in Wisconsin: walled enclosures, earthen ponds, aboveground
