National Resources Inventory
The National Resources Inventory (NRI) is a periodic assessment of the status and changing conditions of the soil, water, and related resources on private land conducted by USDA’s Natural Resources Conservation Service (NRCS). The survey has been conducted at 5-year intervals since 1977, most recently in 2007, though a 2010 mid-cycle data release occurred in December 2013. NRCS released initial results from the 1997 survey in late 1999. The 2010 report includes comparison of the data relative to 1982.
Summary pages exist for soil erosion, land use status and trends, development of non-federal rural land, and rangeland.
