Explain the features of Black Soils.
Answers
Answer:
- Black soils are made up of extremely fine ; clayey material. They are well-known for their capacity to hold moisture. They are rich in soil nutrients such as calcium carbonate, magnesium, potash and lime. They develop deep cracks during hot weather, which helps in the proper aeration of the soil.
Answer:
Explanation:
Explanation:
The black colour of the soil is due to the presence of titaniferous magnetite, compounds of iron and aluminium, humus and colloidal hydrated double iron and aluminium silicate.
The characteristics of black soil are-
clayey texture and are highly fertile
the structure of these soils is cloddish or occasionally friable
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
calcareous and neutral to mild alkaline in reaction, high
in carbon exchange capacity and low in organic matter
self-ploughing and comparatively less fertile on the uplands than
on the lowlands.
These soils are well suited to leguminous crops like cotton, citrus fruits, millets, wheat, linseed, castor, tobacco, sugar cane, and safflower.
