Assessment of the Effects of Conservation Practices on Cultivated Cropland in the Arkansas-White-Red Basin
On May 31, 2013, NRCS released the CEAP-Cropland report on the effects of conservation practices on cropland in the Arkansas-White-Red Basin.
This report is the sixth 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.
Computer modeling simulations indicate that farmers’ use of conservation practices in the Arkansas-White-Red Basin has made good progress toward reducing sediment, nutrient, and pesticide losses from farm fields and subsequent loadings in rivers and streams in the region. However, significant conservation treatment is still needed to reduce nonpoint agricultural sources of pollution. The most pervasive conservation concern in the region is wind erosion. Comprehensive conservation planning and implementation that includes combinations of erosion-control and nutrient management practices are essential. Targeting the cropland that is most vulnerable to sediment or nutrient loss or that has the least conservation treatment in place will provide the greatest return on the conservation investment. More specific details on effects of practices are discussed in the full report and in the summary documents.
