The USDA also manages the Alaska Soil Survey, a scientific inventory of soil resources in 31 different regions of the state. The data are used for making maps, identifying physical and chemical properties of soils, and supplying current information on potential uses and limitations of soils. The Soil Survey contributes to the Natural Resources Inven-tory that involves monitoring of the changes and trends in natural resource use and condition.
