Relationship between erosion and soil physical properties of temperature and tropical soils

Abstract

PADILLA WASHINGTON A. Relationship Between Erosion and Soil Physical Properties of Temperate and Tropical Soils. (Under the direction of Dr. William E. Larson). Three soils, Inceptisol, Mollisol and Oxisol, having large differences in physical and chemical characteristics were subjected to simulated rain in the laboratory. Physical and chemical analyses were conducted on representativa samples to develop relationships between soil loss and soil physical parameters. The effect of clay as a binding agent in the improvement of the stability of surface soil aggregates to control soil water erosion was also evaluated. Aggregate stability appeared to be one of the most important parameters with high influence in controlling soil loss in the three soils.
