Manure Storage Structure
Manure storage structures are designed to temporarily store waste as part of an agricultural waste management system. The type of structure used depends on the livestock operation, waste management system, and planned field application. The options range from above or below ground pits to sheltered concrete slabs to pits underneath a confinement facility. The purpose of the structures is to safely contain the manure and minimize nutrient loss and pollution of water bodies by preventing runoff.
Nutrient management is a practice that involves managing the amount, placement, and timing of plant nutrients to obtain maximum yields and minimize the risk of surface and groundwater pollution. Soil tests are a key component in developing a nutrient rate recommendation as well as crop sequence. Nutrient management helps to eliminate applying excess nutrients and helps reduce the likelihood of those nutrients reaching water bodies. By eliminating the use of excess nutrients, you can save money as well as maximize crop production.
Prescribed grazing controls the amount and location of grazing. It manages the number of animals, the grazing length, and timing of grazing to allow the plants to recover and meet planned objectives. Rotational grazing techniques are used to control grazing patterns and reduce the amount of bare soil due to overgrazing. Some of the goals include improving the quantity and quality of forage, improving or maintaining surface and/or subsurface water quality, and reducing accelerated soil erosion.
Grade Stabilization Structure
In areas where there is an existing low area, channel, or gully, grade stabilization structures can be built to help prevent soil erosion and protect water quality by collecting and storing runoff water. The goals of this practice are to stabilize grade (slope), reduce gully erosion, and improve water quality. A dam is built across the gully or low area and a basin is dug out behind the dam to pond water. An overflow pipe controls the water level and allows water to spill through the dam without causing erosion.
Windbreaks are multiple rows of coniferous trees or a combination of coniferous and deciduous trees planted to protect a farmstead or feedlot from wind and snow. Often, one or two rows of shrubs are also planted. The purpose of a windbreak is to slow wind on the downwind side of the windbreak, which reduces wind erosion, provide shelter from the wind for livestock and homes, and also function as a living snow fence to trap snow.
