SOIL TAXONOMY: AN OVERVIEW

Soil Taxonomy is a comprehensive soil classification developed from 1951 to 1974. In synthesizing the system, all soil properties were considered but selection of differentiating criteria was guided by modern theories of soil genesis. To the degree permitted by present knowledge, the class limits are defined in quantitative terms. The system was designed to be uniformly usable and applicable by competent soil scientists regardless of their area of training and experience. In this system, classification is objective in that it proceeds from properties of the soils themselves and not from the beliefs of the pedologist about soils in general. The system was intended to embrace all known kinds of soils including cultivated and eroded soils. Definitions for a few classes are incomplete because of lack of sufficient data. Soil Taxonomy is a six-category system that permits aggregation of soil data and interpretations at various levels of generalization, whether they are displayed as maps or statistics. It is the only soil classification with a consistent, systematic nomenclature that indicates location in the system and something about the properties of the soils in each class. Soil properties that are important for plant growth also affect the performance of soils for engineering and other nonfarm uses. Soil Taxonomy is a tool for communicating about soils and for extending modern technology into newly developing areas. Interpretations can be made for almost all farm and nonfarm uses. /Author/
