World Reference Base for Soil Resources

The World Reference Base for Soil Resources (WRB) is an international system for classifying and naming soils based on their physical and chemical properties. It helps scientists and land managers understand soil types across different regions by providing a common framework. The system considers features like mineral content, structure, color, and characteristics of soil horizons (layers). WRB enables effective communication about soils globally, supporting agriculture, land use planning, and environmental management by offering a standardized way to describe soil diversity and suitability for various purposes.
