Granular and crumb structure are usually located at the soil surface in the A horizon. The subsoil, predominantly the B horizon, has subangular blocky, blocky, columnar or prismatic structure.

Where are granules?

Granules found in plastids or in the cytoplasm, assumed to be food reserves, often of glycogen or other carbohydrate polymers. In prokaryotes, nutrients and reserves may be stored in the cytoplasm in the form of glycogen, lipids, polyphosphate, or in some cases, sulfur or nitrogen.

What is granular soil?

Granular soil means gravel, sand, or silt, (coarse grained soil) with little or no clay content. Granular soil has no cohesive strength. Some moist granular soils exhibit apparent cohesion. Granular soil cannot be molded when moist and crumbles easily when dry.
