Question

2. Explain the distribution of Black soil in India.
3. What are the characteristics of Red soils?
4. What is soil erosion and soil conservation?
5. Mention the main causes of soil erosion.
6. What are the major effects of soil erosion?​

Answer 1

1. On the basis of genesis, colour, composition and location, the soils of India have been classified into: (i) Alluvial soils (ii) Black soils (iii) Red and Yellow soils (iv) Laterite soils (v) Arid soils (vi) Saline soils (vii) Peaty soils (viii) Forest soils.

2. black soil generally found in the mid southern part of India as these soil are rich in minerals such as iron , magnesium and almunium and are made volcanic rock and Lava flow these soil mostly in the following state of India Chhattisgarh, Maharashtra, Gujarat, Andhra Pradesh.

3. It is porous and has a high percentage of iron oxide. In general, it is found to be shallow and its pH value ranges from 6.6 to 8.0. It is loose and aerated and is poor in terms of the quantity of nitrogen, phosphorus, potassium and organic matter. It is not fertile, but it does respond to fertilisers.

4. Soil erosion is the detachment, transportation, and deposition of soil particles. ... Soil conservation is the practice of minimizing soil loss while maximizing agricultural production.

5. Due to human activities like deforestation, overgrazing, construction and mining, etc. Natural forces like wind, glacier and water leads to soil erosion. Wind blows loose soil off flat or sloping land, and is called wind erosion.

6. The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.

Answer 2

Answer:

1.On the basis of genesis, colour, composition and location, the soils of India have been classified into:

(i) Alluvial soils

(ii) Black soils

(iii) Red and Yellow soils

(iv) Laterite soils

(v) Arid soils

(vi) Saline soils

(vii) Peaty soils

(viii) Forest soils.

2.black soil generally found in the mid southern part of India as these soil are rich in minerals such as iron , magnesium and almunium and are made volcanic rock and Lava flow these soil mostly in the following state of India Chhattisgarh, Maharashtra, Gujarat, Andhra Pradesh .

3.It is porous and has a high percentage of iron oxide. In general, it is found to be shallow and its pH value ranges from 6.6 to 8.0. It is loose and aerated and is poor in terms of the quantity of nitrogen, phosphorus, potassium and organic matter. It is not fertile, but it does respond to fertilisers.

4.Soil erosion is the detachment, transportation, and deposition of soil particles. ... Soil conservation is the practice of minimizing soil loss while maximizing agricultural production.

5.The Main Causes And Impacts Of Soil Erosion

• Deforestation for Agriculture Is One of the Top Causes of Soil Erosion.  

• Soil Erosion is Also Caused by Overgrazing, Which Causes Floods too.

• Agrochemicals Cause Soil Erosion and Degradation.  

• Construction and Recreational Activities.

6.The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.
