Answers
Answer:
Black soil
Clayey texture and are highly fertile.
Rich in calcium carbonate, magnesium, potash, and lime but poor in nitrogen and phosphorous.
Highly retentive of moisture, extremely compact and tenacious when wet.
Contractible and develops deep wide cracks on drying.
lateritic soil
Laterite soil develops in areas with high temperature and heavy rainfall. Humus content of the soil is low because most of the micro organisms, particularly the decomposer like bacteria, get destroyed due to high temperature. Laterite soils are suitable for cultivation with adequate doses of manures and fertilizers.
alluvial soil
They are immature and have weak profiles due to their recent origin. Most of the soil is Sandy and clayey soils are not uncommon. Pebbly and gravelly soils are rare. ... The soil is porous because of its loamy (equal proportion of sand and clay) nature.
coastal alluvial soil
- it is the alluvial still present along the coast of India. It is made by the work of sea waves so it is of tidal origin. As it is made by sea waves, it is sandy, porous and saline. It is a less fertile soil.
red soil
The texture of red soil varies from, sand to clay, the majority being loam. Their other characteristics include porous and friable structure, absence of lime, kankar and free carbonates, and small quantity of soluble salts.
