Soil Development Stages: Mohr & Van Baren Order
Mohr and Van Baren classified soil development into distinct stages based on the maturity and characteristics of the soil profile.
Sequence of Soil Development Stages
Understanding the progression helps in classifying soils. The correct order according to this classification is:
- C: Initial stage - The earliest phase where parent material begins to undergo weathering and modification.
- B: Juvenile stage - Soil-forming processes become more active, leading to the initial differentiation of soil horizons.
- A: Verile stage - A stage of significant development where distinct soil horizons are well-formed and soil properties are clearly established.
- D: Senile stage - The soil reaches a state of relative equilibrium or stability, with further development slowing down considerably.
- E: Final stage - Represents the ultimate condition of the soil, which might be a highly stabilized state or one influenced by long-term degradation processes.
This sequence traces the evolution of soil from its basic origins to a mature or final condition.
