Effect of initial clod size on characteristics of splash and wash erosion
MetadataShow full item record
Wash erosion increased as initial clod size increased from 0.5–2 mm to 8–30 mm on a Marshall silty clay loam except in the case of clods from continuous bromegrass (Bromus inermis). Wash losses increased as size increased despite a drop in runoff from the 8–30-mm clods. Final splash loss rates were higher from the 8–30-mm than from the smaller size clods from continuous corn (Zea mays). Splashed material was larger than washed material and both were larger than material forming the seal.
