| Abstract/Contents: | "Vegetative filter strips have been suggested as a management practice below cultivated areas. As runoff enters a filter strip, the flow velocity and transport capacity are reduced and sediment and associated materials are deposited within the strip. The Conservation Research Program had 2,776 contracts covering 28,704 acres of land for the installation of vegetative filter strips through the 6th and 7th sign up periods ending August, 1988. Water quality improvement is the major objective of setting aside acreage for this land use. To appraise projected water quality improvements due to the establishment of filter strips, a series of CREAMS (Chemical, Runoff and Erosion from Agricultural Management Systems) model simulations of before and after installation conditions were conducted. Data were obtained for 230 filter strip sites which included locations from 29 states. Information from the model simulations was combined with the economic costs to assess cost effectiveness and water quality impacts. Model results show an average 62% reduction of sediment at the cost of $43 per ton, and 56% reduction of sediment associated nutrients at a cost of $7 per pound for nitrogen and $11 per pound for phosphorus. Reductions in sediment and associated material were greatest and the filter strips were the most cost effective on drainage areas between 6 and 20 acres. However, filter strips were not found to be effective in reducing soluble nutrients and pesticides. Cost effectiveness of the strips could be increased over their lifetime through continued efforts to enhance land management measures within drainage areas and fields adjacent to the filter strips." |
