The soil and water resources conservation act covered on private land.
Answer: Option C
Explanation:
The Soil and Water Conservation Act is a 1977 law which required the the US Department of Agriculture to periodically draw up 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 is the lead agency who has completed its first and the second appraisals in the early and the late 80s and the last appraisal was started in the early 90s but unfortunately it was not finished.
