A land use study in Shelby County, Iowa, is used as an example of a procedure for studying the land use status of an area. A land use history was obtained for 1950, 1951, 1952, and 1953 on a 2% statistical sample of the land in the county. Detailed soil survey informatiou was available for the sample. The land use history was tabulated by soil units.
All land was classified as to the intensity of cropping and to the intensity of treatment. When so classified, land use data can be readily compared against any appropriate standard. Comparisons of the land use history of two soil units against two different standards, a soil loss standard and a crop yield standard are given. The degree of compliance on all soil units with the soil loss standard is presented.
It was found that there was no significant difference in the way in which any of the upland soils were being used but there is a wide difference in the degree of compliance with the soil loss standard.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
