ABSTRACT
Since the middle of the 20th century, society has been generous in funding research, and this was a period when almost every field of scientific endeavor saw great advances. The development of new research techniques and technologies greatly boosted research outputs during this period. “Classification is a basic requirement of all science and needs to be revised periodically as knowledge increases”. This is the case for all natural systems. For natural sciences, classification “serves as a framework for organizing our knowledge of natural systems including soils and provides a means of communication among scientists, and between scientists and users of the land”. Information on properties of the soil is used to structure a soil classification system. Scientific research from other fields within Soil Sciences, such as Soil Physics, Soil Chemistry, and Soil Mineralogy, provides the basis for the identification and selection of appropriate diagnostic soil properties and attributes for classification, especially for the development of meaningful class limits.
