soil classification
Earth type sorting
Soil classification is the systematic categorization of soils based on their physical and chemical properties—texture, mineral content, drainage, and organic matter.
Different systems exist for different purposes: the USDA system serves agriculture, while engineering classifications assess soil behavior under construction.
The soil classification indicated we'd need deep foundations.
