                  PEDOGENIC STRUCTURES
Pedogenic structure is divided into 7 classes:
1. Granular.
2. Angular blocky.
3. Sub angular blocky.
4. Platy.
5. Wedge.
6. Prismatic.
7. Columnar.
Typical granular structure looks like granola and is most often found in the surface layers. Angular blocky structure is equidimensional with the faces at sharp angles and the peds fit together well. Sub angular blocky structure is more rounded than angular. Platy structure is wider than deep. Wedge structure has elliptical interlocking peds the often show slickened sides. Prismatic structure is vertically
