Soil classification is the process of categorizing soils based on their physical, chemical, and biological properties into different groups or classes. This classification helps in understanding and predicting the behavior and characteristics of soils for various applications such as agriculture, engineering, and environmental management. The most widely used system for soil classification is the Soil Taxonomy developed by the United States Department of Agriculture, which categorizes soils based on factors such as texture, color, moisture content, structure, and composition. Other classification systems include the World Reference Base for Soil Resources and the Unified Soil Classification System. Soil classification is important for land use planning, agricultural practices, construction projects, and environmental assessments.
