Question

Write a note on ‘soils and their variability’ in India.​

Answer 1

Answer:

Soils are very important from the point of view of agriculture, as they are the main ingredient which are important for the purpose of growing crops. Since they are different in quality and composition, different soils are important for growing different crops based on their physical, chemical and biological properties.

Like red soil and alluvial soil being iron rich and potassium rich respectively, Alluvial soil is good for crops like paddy, sugarcane and plantain while red soil is suited for growing grams, groundnut and castor seed, There are soil testing laboratories which give the farmers an idea of the type of soil which their land has, which is useful as the maximum productivity can be achieved only when the right crop is grown on the right soil.

For soils lacking in an particular nutrient, or soils which are losing some nutrient due to intensive farming, fertilizers rich in that particular nutrient are added. Even soil erosion due to wind and rain also causes soil depletion. Soil of different areas are different in quality and depth.

Types of Soil

Soil is very important for agricultural production. It provides nutrition to plant for its growth. The soil on the earth’s curst found in different form and of different depth across regions. The Indian soil classified into variety of groups.These are:

Red Soil: The soil contains significant amount of iron oxides, it gives the red color to the soil. The soil is deficient in fertility and organic matter. It is found mainly in the state of Tamil Nadu, Karnataka, Goa, Andhra Pradesh, Orissa, Daman and Diu, Chhattisgarh, Jharkhand, etc.

Laterite Soil: It is yellowish red or red in color and contains more organic matter than red soil. It is found in the states of Karnataka, Kerala, Madhya Pradesh, Eastern Orissa, Maharashtra, West Bengal, etc. It is useful in growing tea, rubber, coffee in upper hill areas and paddy in lower hill areas.

Black Soil: Its color ranges between dark brown and deep black and contains high amount of organic matter, Its depth variation is very high, Most of the typical black soil obtained from Deccan traps. It is existed in Maharashtra, in some parts of Andhra Pradesh, Gujarat and Tamil Nadu, The soil is generally highly fertile.

Answer 2

Write a note on ‘soils and their variability’ in India.​

Explanation:

• In India, soils are categorised on inherent characteristics and on the basis of the external features as the texture and the soil-forming processes like the color, slope of the land, and moisture content.  

• As per the soil survey of India established in 1956 the consists of 8 varieties of soil in India as Mountian soil found in hilly tracks of the north India and the alluvial or fertile soil found in northern flood plains and the red and the yellow soil that overs the parts of the northeast and east India and parts of the south India.

• The black soil is found in the central India Malwa plateau and Deccan lava traps and is suited to the cultivation of cotton, while the laterite and sandy soil found in the parts of the western Rajasthan and the Gujarat and covers some parts of the southern India.

• The peaty soil is found in degraded places where the soil erosion has taken place n a massive scale and are formed by the dead organic matter. The saline soil that have high degrees of salt and deficiency of calcium are found in Gujarat and Sundebans area.
