SOIL

 

WHAT IS SOIL

Soil is the most important renewable natural resource it is the medium of plant green and supports different types of living organism on the earth the soil is living system it's takes million of years to forms soil up to few CM in depth. Parent Rock and Bedrock climate vegetation and other forms of life and time are important factors in the formation of soil various process of nature such as change in temperature action of running water and glaciers activities of the composition etc contribute to formation of soil chemical an organic changes which take place in the soil and are equally important soil also consists of organic humans and inorganic materials.

Classification of soil

ALLUVIAL SOIL

This is the most widely spread and important soil impact the entire Northern Plains are made of Alluvial soil this happened deposited by their three important Himalayan River systems the Indus Ganga and the Brahmaputra the soils are also extend in Rajasthan and Gujarat through a narrow corridor Alluvial soil is also found in the eastern coastal plains particularly in deltas of Mahanadi Godavari Krishna and Kaveri rivers. 

BLACK SOIL 

Soils are black in colour and are also known as regur soil black soil is ideal for growing cotton and is known as Black cotton soil it is believe that climatic conditions along with the parent Rock material are the important factor for the information of black important soil this type of soil is typical of Deccan trap region spread over the north west Deccan Plateau and its make up of Lava flows.

RED AND YELLOW SOIL

Red   soil develops on crystalline areas of load rainfall in the eastern and the southern part of the Deccan Plateau yellow and red soil are also found in parts of Odisha Chhattisgarh south and part of the middle Ganga plane and along the piedmont zone of the Western Ghats this size develops redish colour due to diffusion of iron in crystalline and metaphoric rock it looks yellow well it occur in hydrate form. 

LATERITE  SOI

Laterite has been deprived from the Latin word letter which means brick the laterite soil develops under the tropical and subtropical climate with alternate wet and dry season the soil is the result of intense leaching due to heavy rain lateritik soil are mostly deep to very acidic pH 6.0 generally deficient in plants nutrients and occur mostly in south and States Western Ghats region of Maharashtra Odisha some part of West Bengal and north east regions. 

ARID SOIL

I will rains from the red to brown in colour they are generally Sandy instructor and saline images in some areas the salt content is very high and common salt is obtained by evaporating the solute to the dry climate high temperature operation is faster and the soil lab humus and moisture the lower origin of the soil are occupied by conquer because of the increasing calcium content download the conquer layer formation in the bottom Origins and infiltration of  water
