Study Notes
Sand Type
- Coarse sand: 1.00 - 0.50 mm
- Very Coarse sand: 2.00 - 1.00 mm
- Medium sand: 0.50 - 0.25 mm
- Fine sand: 0.25 - 0.10 mm
- Very fine sand: 0.10 - 0.05 mm
Soil Structure
- Soil structure is categorized based on the shape of soil particles.
- It's classified into four types:
- Blocky
- Plate-like
- Prismatic
- Granular
- The shape and size of soil aggregates (called peds) determine soil structure.
- Subtypes include:
- Sub-angular blocky
- Angular blocky
- Columnar
- Prismatic
- Granular
- Crumb (shapeless)
