Soil order of Mizoram belongs to
A)
Red and lateritic
B)
Entisol, Alfisol and Inceptisols
C)
Entisol, histosol and inceptisol
D)
Alfisol and inceptisol
The soil classification of Mizoram is based on the USDA Soil Taxonomy. Due to the state's rugged topography, high rainfall, and steep slopes, the soils are characterized by varying degrees of weathering and development.
1. **Inceptisols**: These are the most dominant soil order in Mizoram. They are soils in the early stages of development (incipient soils) and are common in hilly terrains with high leaching.
2. **Alfisols**: These are moderately weathered soils with a clay-enriched subsoil, found in certain plateau or stable slope areas of the state.
3. **Entisols**: These are very young soils with little to no profile development, typically found on steep slopes where erosion is frequent, preventing the soil from maturing.
Comparing the options:
- Option (a) refers to traditional Indian soil classification (Red and Lateritic), not 'Soil Orders' (which refers to the USDA Taxonomy).
- Option (c) includes Histosols (organic/peat soils), which are not a primary characteristic of the general Mizoram landscape.
- Option (d) is incomplete as it omits Entisols, which are prevalent on the state's steep slopes.
Therefore, Option (b) accurately lists the primary soil orders found in the region.
