Study Notes
Soil Types and Characteristics
- Alluvial soil: formed from chemically weathered volcanic ash, found near river banks
- Bentonite soil: contains high percentage of montmorillonite, used as lubricant
- Lacustrine soil: deposited from suspension in still lake water, a type of transported soil
- Residual soil: formed from basalt, dark in color
Soils and Their Characteristics
- Black Cotton soil: contains excess montmorillonite, dark in color, used for growing cotton, also known as Aeoline soil
- Loess soil: uniformly graded wind-blown silt, slightly cemented by calcium compounds and montmorillonite, found in marshy/swampy areas
- Muck soil: mixture of fine-grained inorganic soil and black decomposed organic matter, found in marshy/swampy areas after overflow of water
Glacial and Other Soils
- Glacial soil: highly organic soil, consists of black decomposed organic matter, a type of transported soil
- Peat soil: consists of black decomposed organic matter, highly organic soil
- Cumulose soil: peat + muck, also referred to as "Talus", a type of transported soil
- Colluvial soil: a type of transported soil, also referred to as "Talus"
Red and Marl Soils
- Red soil: formed due to decomposition of plant and animal bones, found in areas of less rainfall in eastern and western ghats
- Marl soil: finely grained calcium carbonate soil of marine origin, found in areas of less rainfall in eastern and western ghats
Loam and Laterite Soils
- Loam soil: mixture of clay, silt, and sand, formed due to leaching (washing out of siliceous compounds and deposition of ferric oxide and aluminium oxide)
- Laterite soil: formed due to leaching, found in hilly regions of eastern and western ghats
Gumbo and Tuff Soils
- Gumbo soil: black, sticky, and highly plastic soil
- Tuff soil: fine-grained slightly cemented volcanic ash, transported by wind or water
