Variable General Info
Grass buffer/forest buffer area ?Comment:This variable pertains to optional Conservation Practices provided by NTT. This variable is constant with respect to the Crop type for the specific application. Forest buffers are linear wooded areas with well-developed root systems, an organic surface layer, and understory vegetation. When they are adjacent to open water they are referred to as riparian forest buffers. Non-riparian buffers are linear wooded areas along down-slope field edges. Forest buffers trap sediment and increase infiltration, thereby reducing sediment and nutrient losses. Forest buffers often include a grass buffer between the field and the forested buffer. If present, please also include the width of the grass buffer. Grass buffers, also known as a filter strips, are an area of vegetation, generally narrow in width and long across the downslope edge of a field, that slows the rate of runoff, allowing sediments, organic matter, and other pollutants that are being conveyed by the water to be removed by settling out. Filter strips reduce erosion and the accompanying sediment-bound pollution. In NTT, filter strips function by providing for better infiltration of soluble nutrients, trapping of sediment, and increased uptake of water and nutrients by the filter strip vegetation. The saturated conductivity value is also modified for filter strip simulation in NTT. The inputs for grass buffers are the same as for forest buffers (see Forest Buffer), with the additional requirement that the user specify type of vegetation. This is the total area of the Riparian Buffer. This field is optional. If left blank, the area will automatically be calculated using the width of the buffer and the length of the field edge (where the field edge is calculated as the square root of the area of the field). |
