Synopsis
Excerpt from Soil Classification: A Comprehensive System
Late in 1936, the then Secretary of Agriculture, Henry A. Wallace, asked that a comprehensive state ment about the soils of the United States and their uses be prepared as the 1938 Yearbook. Although we explained that our knowledge was hardly adequate for the task, the Secretary felt that one of the values of such a book would be evidence of research need. So, despite the shortness of time, the Soil Survey staff prepared a new soil map of the United States, a new statement of the system of classification, and descriptions of the soils as they knew them then. What a year that was! Great soil groups were de fined, including a few new ones. Time was not avail able for detailed descriptions or for adequate field testing. For example, the Planosol group was defined to include those soils of humid and subhumid areas with prominent hardpans and claypans that did not fit into the other groups as formerly defined. It turned out that our definition of Planosol was too broad. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
