This type of soil is black in colour. These soils are also called as regur soils. In the north-western found Deccan Plateau. [5] The soil is suitable for growing cottons, due to which it is also known as black cotton soil. It is believed that the climatic conditions along with the parent rock material are the important factors for the formation ...
The terrain can also be found in small quantities elsewhere (for example, in 1% of Poland, Hungary, and Texas). It also exists in Northeast China, near Harbin. The only true chernozem in Australia is located around Nimmitabel, some of the richest soils on the continent. [7] Previously, there was a black market for the soil in
Terra preta (Portuguese pronunciation: [ˈtɛʁɐ ˈpɾetɐ], literally "black soil" in Portuguese), also known as Amazonian dark earth or Indian black earth, is a type of very dark, fertile anthropogenic soil found in the Amazon Basin.
Most of the region with igneous basaltic rock consists of black soil. These soils have a high clay content, retain moisture and are resistant to erosion, but develop cracks during the dry season. The gneiss peneplain region in the low rainfall areas in the eastern vicinity of the Western Ghats consist of infertile red soil. [32] [37]
Black soil may refer to: Chernozem, fertile black soils found in eastern Europe, Russia, India and the Canadian prairies; Muck (soil), a soil made up primarily of humus from drained swampland; Vertisol, dark cracking soils with a high clay; Terra preta, "black earth" or soil of the Amazon river basin
Black soil are well developed in the Deccan lava region of Maharashtra, Gujarat, and Madhya Pradesh. [82] These contain high percentage of clay and are moisture retentive. [90] Red soils are found in Tamil Nadu, Karnataka plateau, Andhra plateau, Chota Nagpur plateau and the Aravallis. [82] These are deficient in nitrogen, phosphorus and humus.
The black, volcanic soil is ideal for the cultivation of cotton, and textile manufacture is an important industry. Large centres of textile production include Indore, Ujjain and Nagda. Maheshwar is known for its fine Maheshwari saris, and Mandsaur for its coarse woollen blankets. Handicrafts are an important source of income for the tribal ...
The soils of Maharashtra are residual, derived from the underlying basalts. In the semi-dry plateau, the regur (black-cotton soil) is clayey, rich in iron, but poor in nitrogen and organic matter; it is moisture-retentive. Where redeposited along the river valleys, those kali soils are deeper and heavier, better suited for rabi crops.
