Creating strips of vegetation within a field can provide a physical barrier that slows the flow of overland runoff, increases infiltration and prevents soil, sediment and nutrient loss from fields. Riparian buffer strips are next to watercourses between m away from the bank whereas in-field buffer strips are found adjacent to field boundaries and across fields. Buffer strips can contain long grasses, trees and shrubs. Alongside a river they usually require fencing to prevent livestock from accessing both the buffer strip and the watercourse itself. Alternative drinking sources, such as gravity fed drinking troughs, solar pumps or pasture pumps can be used to provide livestock with access to water. Vegetation in the buffer strip increases the roughness of the land surface, which slows runoff as well as increasing the interception and absorption of rainfall and therefore provide a great Natural Flood Management NFM benefit.

Many nutrient mitigation best management practices BMP are promoted by state and federal agencies to protect water quality from animal agriculture. The measured effectiveness of these is highly variable in the research literature. Here, we establish pre- and post-BMP monitoring to evaluate the effectiveness of fencing out cattle from the riparian zone on water quality, specifically, phosphorus P loads and concentrations. We collected water samples year-round both before and after a cattle exclusion was established at a small mixed dairy and beef cattle pasture where cattle have historically grazed with unrestricted access to first and second order streams, and analyzed for soluble reactive and total P.

A buffer strip along the edge of this field in southern Minnesota helps prevent soil and nutrient runoff into the nearby river. Mark Dayton told the audience that he would ask the legislature to require a foot buffer along all Minnesota waterways. Nonetheless, the proposal has generated a lot of discussion. Meantime, here are answers to frequently asked questions about buffer strips, with a particular focus on how buffers relate to farming in Minnesota. What is a buffer strip?
