The natural cloddiness of soils largely determines their susceptibility to wind erosion. As cloddiness decreases, greater amounts of cover and surface roughness are needed to reduce soil losses to insignificant amounts. The use of a rotary sieve to help characterize soils for natural cloddiness is proposed. Procedures to be used are discussed. Results are reported from studies made of some of the extensive soil types of the southern High Plains of Texas. A study of the climate of the area is reported also. Yields of high‐residue‐producing crops are predicted for Amarillo fine sandy loam in several areas with small but significant differences in amounts of rainfall, using results of climatic studies and projection of yields from experiment stations. The correlation between grain yields and crop residues is discussed. The natural cloddiness of soils, the residue needed to protect them, and the expected yields of high‐residue‐producing crops are proposed as additional criteria for determining the capability classification of the soils studied. The soils are classified, using the proposed method of classification.
