The U.S. Soil Conservation Act of 1935 established the Soil Conservation Service.  This agency deals with soil erosion problems. 

In 1903, Hugh Hammond Bennett, a soils scientist, went to work for the Bureau of Soils in the U.S. Department of Agriculture.  In 1933, after years of Bennett's research and urging, the Soil Erosion Service was established in the U.S. Department of the Interior.  In 1935, it was transferred to the U.S. Department of Agriculture, and later that year Congress passed the Soil Conservation Act, establishing this organization as the Soil Conservation Service.  Bennett was its first director.

In its eary years, the Soil Conservation Service carried out numerous soil surveys of various sections of the United States.  The agency also showed insight into many developing conservational problems, including soil salinity control.  It also published, and continues to do so, maps of soil erosion and related problems.  It has continued to practice all these activities in the years since, adding to its repertoire by providing computer databases for scientific research, such as pesticides.  Although the United States still must deal with soil erosion issues, no doubt these would have been much more consequential without the Soil Conservation Act and Service.
