AB Congress mandated (P.L. 92-500, Sections 108d and 108e) that the U.S. Army Corps of Engineers design and develop a program for the rehabilitation and environmental repair of Lake Erie. The Corps' Lake Erie Wastewater Management Study (LEWMS) identified P as the nutrient most affecting the extent of eutrophication in Lake Erie, and showed that the rural, primarily agricultural, diffuse P load needed to be reduced by about 26% to reduce eutrophication significantly. Accelerated implementation of conservation tillage, including no-till, on soils suited to these practices on the U.S. side of the Lake Erie Basin can achieve the required reduction in the diffuse P load. Rates of adoption of conservation tillage, and concurrent reductions in the diffuse P load, by U.S. farmers under existing conditions and with a program for accelerated implementation are presented.
