Soil classification systems
Soil classification systems categorize soils based on their physical and chemical properties, helping us understand their behavior and suitability for various uses. These systems consider aspects like grain size, mineral composition, and how soils react to water and other elements. For example, some soils are sandy and drain quickly, while others are clayey and hold water. Different countries or organizations have developed their own classification methods, such as the USDA Soil Taxonomy or the Unified Soil Classification System, to standardize how soils are identified and described for agriculture, engineering, and environmental purposes.
