The German Soil Systematics and the Rationale Behind Its Revision
Journal of Plant Nutrition and Soil Science, EarlyView.ABSTRACT Background The German Soil Systematics is a pedogenetic classification based on the morphological expressions of pedogenic processes and has been developed over several stages since 1952. The system has successfully been in use for soil classification and soil survey for almost 70 years.
