From the author: We evaluated changes in field costs and revenues with each of seven conservation best management practices (BMP) and two nutrient management programs (NMP) for three sites in the Susquehanna River Basin in Pennsylvania. Field layouts, rotation selection, BMP design, and CREAMS modeling of sediment and nutrient losses are reported elsewhere. BMP implementation costs, field operation costs, and crop revenues were calculated with each BMP as well as the baseline condition representing present practices. The present value of net field revenue over a 10-year period for each BMP/NMP combination is compared to that of the baseline. The BMP/NMP combinations are compared for cost-effectiveness in reducing sediment, nitrogen, and phosphorus losses. Nonstructural BMPs (no-till, contour, contour with waterways, strip crop with waterways, filter strips) produced less reduction in net field income than did structural BMPs (terraces with waterways, parallel tile outlet terraces, sediment basins). In some instances nonstructural BMPs increased net field income relative to the baseline even without including cost sharing. When combined with the improved NMP (improved manure storage and nutrient application matched to crop needs), nonstructural BMPs produced higher net field incomes than did structural BMPs. The most cost-effective BMP/NMP combinations were no-till, filter strip, and strip crop with waterways. At one of the sites, the most cost-effective combination included the improved NMP. At the other two sites, a BMP without improved NMP was more cost-effective.
