Effect of Initial Clod Size on Characteristics of Splash and Wash Erosion

Abstract

Abstract 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.
