OSHA classifies soils into four categories: Solid Rock, Type A, Type B, and Type C. Solid Rock is the most stable, and Type C soil is the least stable. Soils are typed not only by how cohesive they are, but also by the conditions in which they are found.

Type C soil is the least stable type of soil. Type C includes granular soils in which particles don't stick together and cohesive soils with a low unconfined compressive strength; 0.5 tons per square foot or less.

Is Mollisol good for agriculture?
Key Characteristics: Mollisols – Grassland Soils
Generally very fertile for plant growth due to clay and organic matter content. Considered to be among the most fertile soils on Earth.
How do I know if my soil is good?
Signs of healthy soil include plenty of underground animal and plant activity, such as earthworms and fungi. Soil that is rich in organic matter tends to be darker and crumbles off of the roots of plants you pull up. A healthy, spread-out root system is also a sign of good soil.

Loam soil is a combination of three different types of soil—sand, silt, and clay—each with their own characteristics. Sand particles are the largest. Silt particles are medium-sized, absorb moisture better than sand, and help the sand and clay mix together effectively.
