Study of Cropping Effects on Soil Properties Related to Water Infiltration, Runoff and Soil Properties Related to Water Infiltration, Runoff and Soil Loss Using Simple Laboratory Methods

摘要

The objectives of the study were to determine differences between the effects of soybean and corn plant materials on stability of soil incubated in a laboratory under constant temperature and water contents. Three different laboratory measures of soil stability were used, (1) soil splash detachment from a waterdrop; (2) soil shear strength measured with a fall cone device; and (3) geometric mean diameter of fresh (non-air-dried) wet sieved soil. Soil for the experiment was collected from within the upper 10 cm of continuously fallow Mexico silt loam soil.
