Which geographical factors are responsible for the evolution of black soil?
Answers
Answer:
(1) Climatic conditions like temperature, rainfall etc. along with present rock material are important factors for making of black soil. The parent rock is volcanic rock.
(2) It is ideal for growing cotton because:
(i) It has capacity to hold moisture.
(ii) They are rich in calcium carbonate, magnesium, potash and lime.
(iii) This soil is also known as black cotton soil,
(iv) They develop deep cracks during hot weather, which help in the proper aeration of the soil.
Deccan trap that includes plateaus of Maharashtra, Saurashtra, Malwa, Madhya Pradesh and Chattishgarh and extend in the South-East direction along the Godavari and Krishna valleys. 70 million years ago there were huge volcanic eruptions taking place in North-Western part of Indian plateau and lava spread North-West to South-East direction covering a huge area. Over these region the rocks are gradually degraded and black soil formed.
The soil is famous for its cotton growing capacity. Conducive conditions for such cultivation is its moisture retaining capacity and extensive fertile layers along its profile. The soil is clayey in nature and rich in soil nutrients like calcium, carbonate, magnesium, potash and lime.
Black soil or regur in central India and also called as Karagil in the lower Ganga plains of Uttar Pradesh. is the least affected by climatic factors per se. It is a type of soil that is formed directly as a result of weathering of parent rock and still shows the properties of the rock.Black soil is formed from igneous rocks like basalt and hence can be found in areas that experience volcanic activity or once experienced it. The regur in India falls in the second category.
