Abstract
It is the purpose of this study to compare the morphologic, chemical, and physical properties of five Sinai profiles—two from Day County and one from each of the following counties: Brookings, Kingsbury, and Minnehaha; to compare climatic conditions of these areas; to compare Sinai soil associates of these areas; and to make a recommendation as to the classification of these soils. Profiles of the five soils used in this investigation were sampled from pits dug in cultivated fields. All samples were air dried in the laboratory and sieved as necessary. The pipette method of mechanical analysis, slightly modified, was used, as was the dry combustion method for total carbon and the Kjeldahl method for the total nitrogen determination. Results are displayed in multiple tables in the appropriate section of the manuscript
