When the Soil Erosion Service was established as part of the
United States Department of the Interior in September 1933, Bennett became the director. He continued to speak out on soil conservation issues, especially through the
Dust Bowl years, and eventually influenced the passage of the soil conservation act of April 27, 1935, which created the Soil Conservation Service at the USDA. He remained at the head of that organization until he retired in 1951. Hammond hired
Henry Howard Finnell to put his soil expertise to work: Hugh Hammond Bennett, the head of the Soil Conservation Service, put Finnell in charge of Region Six, the hardest-hit area of the country; code name: "
Operation Dustbowl." Finnell set up shop north of
Dalhart. Areas where the soil was not suitable for cultivation were turned back to grassland. Thirteen other demonstration projects, manned by
CCC and
WPA workers, put Finnell's moisture-conserving ideas to the test, with great success. By May of 1936, nearly 40,000 farmers had joined him, and 5.5 million acres were under new terraced and contour-listed cultivation. At the end of 1937, despite the persistent dust storms, the amount of dangerously eroded land had been reduced by more than half. Largely in response to Bennett's campaign for soil conservation, Representative James P. Buchanan of Texas attached an amendment to the 1930 appropriations bill authorizing the USDA to establish a series of soil erosion experiment stations. The Coon Creek Watershed Project, in southwestern Wisconsin, was the first of many watershed-based projects initiated to demonstrate soil conservation practices to farmers. The locations for these stations were selected by Bennett, and involved teams of researchers establishing plots to measure erosion conditions under various types of crops, soils, rotations, and their responses to different agricultural managements practices and structures. == Recognition ==
