The purpose and use of soil classification and mapping

Soil classification deals with the systematic categorization of soils based on distinguishing characteristics as well as criteria that dictate choices in use.

While in some countries of the world soil classification is an important and integral part of agricultural planning and development, in other countries it is no being used to a similar extent as a guide for proper land use. Modern soil classification is based upon the nature of the soil section or soil profile, which reflects the influence of the various factors of soil formation, including climate and vegetation, drainage and the parent material from which the soil was derived. The essence of modern soil classification is the recognition of individual soil types as natural units, and an appreciation of their properties and productive capacities.

The most practical purpose of soil classification and mapping is to provide a systematic basis for the study of crop and soil relationship with the view to increasing productivity and to help in soil conservation and reclamation. This purpose embraces a number of widely recognized aspects, including the prediction of crop and soil behavior on new land for agricultural production, fertilizer requirements on both old and new land. According to the classification individual soil types may be identified and mapped in detailed soil surveys, or the individual soil types may be mapped as groups in reconnaissance surveys.
