Base exchange capacity is low. Alkali soils are barren and are also called usars in Hindi. The scarcity of water and excessive accumulation of saks make the soils unfit for cultivation. The chemical composition of the alluvial soils makes this group of soils as one of the most fertile in the world. On the other hand, the soils of the Extra-Peninsula are formed due to the depositional work of rivers and wind.

Black soils are credited with high fertility. It requires densification to increase its bearing capacity and shearing strength. Soils are salty and they contain good amount of alkalies and humus content. Mumbai, Mysore, Andhra Pradesh, West Bengal, Assam, Orissa, Chhota Nagpur covering a total area of about 3,50,000 square kilometres. Supporters of this theory, such as E.

However, Maharashtra, Madhya Prades and Gujarat have the largest share of the soil. These soils are mostly composed as calcite depositions. Soils are generally rich in potash but nitrogen contain is low. Their water holding capacity is very low. On the other hand, marshy soils are found in coastal areas of some states such as Tamil Nadu, Bihar, Almora district of Uttaranchal and Sunderbans of West Bengal. Geologically, Indian soils can broadly be divided into two main types: a Soils of peninsular India and b Soils of extra-peninsular India.

Some soils are salty mainly due to presence of alkali salts in them. This is a very logical classification of Indian soils and has gained wide acceptance. But, factors such as vegetation, climatic conditions, human activities for e. This type of soil is found in arid and semi-arid areas. At the same time, the activation of microbiological processes when chernozems are cultivated promotes the mobilization of nitrogen and phosphorus. The soils of dry regions are rich in K, P and alkalies.

Short notes on the Black Soils

They are mainly found in the river valleys and deltas. These all layers horizons put together form a soil profile. They cover almost the whole of Tamil Nadu, Andhra Pradesh, Chhattisgarh, Karnataka, Maharashtra and parts of Orissa. Soil types are classified according to many more factors. Matasi is yellow loamy clay soil. This is why vegetation is very poor, forests are totally absent and desert is spreading progressively eastward in Rajasthan.

The red soils occupy a vast area of about 3. It is found in the northern plains beginning from Punjab to West Bengal and Assam. Other crops include wheat, jowar, millets, linseed, castor, tobacco, sugarcane, safflower, vegetables etc. Most of the time these soil are used to make bricks due to presence of large amounts of iron. Sometimes, the phosphate content may be high, probably present in the form of iron phosphate but potash is deficient. Large varieties of vegetables and fruits are also successfully grown on the black soils.

Soil Map of India

It occurs in patches in the Wainganga valley and north­ern Konkan coast. The zone of chernozems is subdivided from north to south into the subzones of podzolized, leached, typical, common, and southern chernozems. Laterite and Lateritic Soils 5. On the uplands these soils are comparatively less fertile than on the low lands. Black soil is extremely fine and clayey and has the capacity to hold a lot of moisture.

Geologically, the alluvium of the Great plain of India is divided into newer or younger khadar and older bhangar soils. The nitrogen content is low, but the phosphate content is as high as in normal alluvial soil. They are well known for their capacity to hold moisture. The soil is made up of particles like silt, sand and clay. Laterite soil generally is poor in lime and deficient in nitrogen. The black colour of these soils has been attributed by some scientists to the presence of a small proportion of titaniferous magnetite or even to iron and black constituents of the parent rock. It is concentrated over Deccan Lava Tract which includes parts of Maharashtra, Chhattisgarh, Madhya Pradesh, Gujarat, Andhra Pradesh and Tamil Nadu.
