Press Release from the USDA
A new USDA study shows that farmers using combinations of erosion-control and nutrient-management practices on cultivated cropland are reducing losses of sediment, nitrogen and phosphorous from farm fields and decreasing the movement of these materials to the Great Lakes and their associated waterways.
“The Great Lakes Conservation Effects Assessment Project (CEAP) study confirms that good conservation planning and implementation have reduced loadings of sediment and nutrients to waterways throughout the region,” Agriculture Secretary Tom Vilsack said today. “The Administration appreciates the actions of every farmer who is stepping up to implement conservation practices, protect vital farmlands and strengthen local economies. At the same time, we also see opportunities for even further progress.”
The CEAP study, prepared by USDA’s Natural Resources Conservation Service (NRCS), estimates that the use of conservation tillage and other conservation practices has resulted in a 50 percent decline in sediment entering rivers and streams, along with 36 and 37 percent declines, respectively, in phosphorus and nitrogen loading.
