| Abstract: | Summary A 0- to 6-inch sample of residual mineral soil was taken from 258 locations in northern California's mountain lands. Standard textural, organic matter, and erodibility analyses were made on these soil samples. These variables were then related to climatic parameters, parent material, and cover types by regression analysis. Variation in erodibility was found to be significantly correlated with parent material, cover type and climate. The acid igneous and schist rock types were more erodible than the more basic and ultramafic types. Soils developed under fir were found to be less erodible than those developed under pine, brush, or grass. |
