(August 2017) (Learn how and when to remove this template message) </Td> </Tr> <P> The Soil and Water Conservation Act (RCA) is a 1977 law (P.L. 95 - 192) that requires USDA to periodically prepare a national plan for soil and water conservation on private lands based on an inventory and appraisal of existing resource conditions and trends . Natural Resources Conservation Service (NRCS) is the lead agency in this effort, and completed appraisals in the early 1980s and late 1980s; a third appraisal was initiated in the early 1990s, but not completed . Only one national plan was adopted by USDA, in 1982 . Many of the activities envisioned when the RCA was enacted are being carried out, but it has not resulted in a single omnibus plan addressing conservation needs and priorities on private lands yet . </P> <Ul> <Li> This article incorporates public domain material from the Congressional Research Service document "Report for Congress: Agriculture: A Glossary of Terms, Programs, and Laws, 2005 Edition" by Jasper Womach . </Li> </Ul>
