The U.S. Department of Agriculture is inviting public comment through June 4 on proposed changes in its conservation programs.

USDA officials say changes are necessary to reduce erosion levels on highly erodible land, to help keep contaminants out of surface and subsurface water and to address other land and water resource conditions and trends.Details of USDA conservation program proposals may be examined at any Soil Conservation office or Agricultural Stabilization and Conservation Service office. Comments from farmers, ranchers, environmentalists and others should be mailed to the Soil Conservation Service, Box 11350, Salt Lake City 84147.
