The alluvial soil consists of various proportions of sand, silt and clay. Lateritic soils are acidic (pH<6.0) in nature and generally deficient in plant nutrients. Human activities such as deforestation, overgrazing, mining and quarrying have contributed significantly to land degradation. On the basis of the factors responsible for soil formation, colour, thickness, texture, age, chemical and physical properties, the soils of India are classified in different types as mentioned below. In the snow covered areas of Himalayas, they experience denudation and are acidic with low humus content. Soil also consists of organic (humus) and inorganic materials. 2. Abiotic Resources: All those things which are composed of non-living things are called abiotic resources. The running water cuts through the clayey soils and makes deep channels as gullies. Most of the soils are derived from the sediments deposited by rivers as in the Indo-Gangetic plain. The classification of soils has pro-found effects on a variety of soil properties from land use to agro-nomic productivity. Spread: This type of soil is typical of the Deccan trap (Basalt) region spread over northwest Deccan plateau and is made up of lava flows. Chapter 1 of Class 10 Geography introduces you to resources and its classification. clayey material and well-known for their capacity to hold moisture. These soils are generally poor in phosphoric contents. These soils are of two types – old alluvial soil known as bangar and new alluvial soil known as khadar.

Soil texture varies according to the mountain environment. Community Owned Resources are accessible to all the members of the community. The soils of Peninsular India are formed by the decomposition of rocks in situ, i.e. Soils in the drier areas are more alkaline and can be productive after proper treatment and irrigation. Biotic Resources are obtained from the biosphere and have life. 3. Property: Laterite has been derived from the Latin word ‘later’ which means brick. The soil is sticky when wet and difficult to work on unless tilled immediately after the first shower or during the pre-monsoon period. Some soils are sticky, others will not stick together at all, and others feel "doughy" or "spongy". Soil particles are large and non-uniform in size. The soil is ideal for growing cotton and is also known as black cotton soil. The Alluvial Soil is deposited by 3 important Himalayan river systems – the Indus, the Ganga and the Brahmaputra. Resource planning is essential for the sustainable existence of all forms of life. Laterite soils are suitable for cultivation with adequate doses of manures and fertilizers. Soils may be assigned to textural classes depending on the proportions of sand, silt and clay-size particles. This type of soil is typical of the Deccan trap (Basalt) region spread over northwest Deccan plateau and is made up of lava flows. It contributes the largest share to the country’s agricultural production. Such soils are more common in piedmont plains such as Duars, Chos and Terai. In some areas, the salt content is very high and common salt is obtained by evaporating the water. Your email address will not be published. This leads to soil erosion. Ideal Crop: Cotton hence another name black cotton soil. Or India has approximately 89000 species of animals, 1200 of birds and 2500 species of fishes. In addition, they are rich in soil nutrients, such as calcium carbonate, magnesium, potash and lime.
