The US Occupational Safety and Health Administration (OSHA) uses 5 soil classifications:
Stable Rock
Type A - cohesive, plastic soils with unconfined compressive strength greater than 1.5 ton/sf
Type B - cohesive soils with unconfined compressive strength between 0.5 and 1.5 ton/sf
Type C - granular or cohesive soils with unconfined compressive strength less than 0.5 ton.sf
Type C60
vascilar non vascular

what are four main soils used to classify soils
The three main factors used to classify soil are texture (proportion of sand, silt, and clay), structure (arrangement of soil particles), and composition (mineral and organic matter content). These factors help determine the characteristics and suitability of the soil for different uses.

no, but scientists are.
humus. (pronounced hugh-muss) sand, and clay
Scientists classify different types of soil based on factors such as particle size, mineral composition, soil texture, soil structure, and organic content. These factors help determine properties like drainage, fertility, and water retention capacity of the soil, which are important for agriculture and environmental studies.

Scientists classify soil based on factors such as texture (sand, silt, clay), structure (how soil particles are arranged), pH level, organic matter content, and composition of minerals present. These factors help determine the soil's fertility, drainage, and ability to support plant growth.
The three main factors used to classify soil are texture (particle size), structure (arrangement of soil particles), and composition (types of minerals and organic materials present). These factors help determine the soil's properties, such as drainage ability, nutrient holding capacity, and suitability for various types of plant growth.
