Abstract : To develop a methodology for predicting soil texture, an intensive literature review was made of the interrelations among genetic factors, natural and cultural processes, and soil formations, and a considerable quantity of pertinent data from the field and literature was collected for the Federal Republic of Germany and the eastern United States. The literature was summarized and the data shown. A total of 1309 soil profiles were examined. Every profile was classified in Unified Soil Classification System terms and 1285 of these were also classified in U.S. Department of Agriculture terms. Each profile consisted of two soil samples, one from the 0- to 6-in. depth and the other from the 6- to 12-in. depth. The soils data were shown in tabular and graphic form representing the occurrence of soil types for given rock types (residual soils) and soil types in glacial and aeolian deposits, respectively. A tabular breakdown of soil types according to slope classes also was shown. The significant findings of the literature review and the soil-rock data were synthesized to evolve the subject methodology. (Author)
