The Web Soil Survey is a database containing information about the soil in different regions of the United States. It is compiled and maintained by the Natural Resources Conservation Service, a federal agency within the U.S. Department of Agriculture.
The Web Soil Survey contains detailed maps and tables of soil data for 95 percent of U.S. counties. This information is used by farmers to determine the soil quality and suitability for growing crops, and by real estate agents and engineers who are considering building a structure in a certain area. The Web Soil Survey lists the various types of soil present within a given area of interest, as well as data related to disaster recovery planning, land classification, military operations, vegetative productivity and waste and water management.
