FAQs

1. How do you determine soil classes? Soil classes are typically determined based on soil characteristics such as texture, composition, organic matter content, and more. Various classification systems exist, and soil scientists use a combination of field observations and laboratory tests to categorize soils.

2. What are the 12 classes of soil? There isn’t a universal 12-class system for soil classification. Soil classification systems vary by region and organization. The most widely used system in the United States is the USDA Soil Taxonomy, which includes multiple soil orders, suborders, and more specific categories.
