On March 15, 2011, NRCS chief Dave White announced the release of the CEAP-Cropland report on the effects of conservation practices on cropland in the Chesapeake Bay region (listen to the announcement). This report is the second in a series of regional reports that continues the tradition within USDA of assessing the status, condition, and trends of natural resources to determine how to improve conservation programs to best meet the Nation’s needs. These reports use a sampling and modeling approach to quantify the environmental benefits that farmers and conservation programs are currently providing to society, and explore prospects for attaining additional benefits with further conservation treatment. These documents require Adobe Acrobat
Computer modeling simulations indicate that conservation practice use in the Chesapeake Bay region has reduced sediment, nutrient, and pesticide losses from farm fields. However, there remain significant opportunities for reducing nonpoint agricultural sources of pollution. Major findings from the study are listed below. More specific details on effects of practices are in the full report and the summary documents.
Technical information on the methodology for CEAP Cropland studies in general, including the one on the Chesapeake Bay region, and documentation reports on the modeling methodology, models and databases, are available at http://www.nrcs.usda.gov/technical/nri/ceap/cropland.html. Detailed information on the CEAP Cropland Farmer Surveys conducted by NASS is available at http://www.nrcs.usda.gov/technical/nri/ceap/surveys.html. Information on other CEAP projects addressing watersheds, wetlands, wildlife, and grazing lands in the Chesapeake Bay region are also available on the CEAP website. |
