Physical Characteristics of Four Mississippi Soils

Abstract

AbstractFour silt loam soils in Warren County, Mississippi, were studied intensively to determine to what extent a soil series, as normally mapped by types, delimits the physical properties of the surface foot.The degree of variation between individual samples implied that intensive sampling is necessary to typify physical properties of these soils. Means differed significantly between series in clay content, bulk density, and moisture‐tension values. However, the range in values suggests that, for strength classification and simliar purposes depending upon physical properties, similar textural types in different series can often be combined.Memphis and Loring, designated upland soils, had considerably more clay than the bottom‐land soils Falaya and Collins. As a result of erosion, variation in clay content in the plow layer was far greater in upland than in bottom‐land soils.
