FAO World Reference Base for Soil Resources (WRB)

The FAO World Reference Base for Soil Resources (WRB) is an international system for classifying and naming soils. Developed by the Food and Agriculture Organization (FAO), it helps scientists and land managers communicate clearly about soil types globally. The WRB categorizes soils based on their physical and chemical properties, making it easier to understand their characteristics and functions. This classification system supports sustainable land use, agriculture, and environmental conservation by providing a common language for soil assessment and research across different regions and countries.
