Investigations of strip cropping on some of the residual soils of southeastern Ohio indicate that variations in the effectiveness of this erosion control practice are due in part to differences in physical properties of the soil as well as to cultural practices. Variations in structure on different soil types and under different de.grees of erosion on the same soil type were readily observed in the field. Although the effect of structure upon erosion has been thoroughly reviewed by Baver (l, 2, 3), Lutz (9), Yoder (10) , and many others, the soils of southeastern Ohio derived from sandstone, shale and limestone possess a type of structure which has not been previously investigated. Sheet erosion of these soils exposes a compact subsoil, very blocky in structure, which disintegrates into prismatic aggregates or fragments. Most of the cultivated soils in this area contain varying amounts of these prismatic aggregates in their surface. Studies have been made during the past season of the physical properties of the various types of soil aggregates present in the residual soils of this area to determine the relationship between the type of structure and the erosion process.
