Question

give 5 points of difference between alluvial soil and red soil​

Answer 1

Answer:

Alluvial Soil  

1. Alluvial soil is very fertile as it is rich in mineral nutrients like potash and lime.  

2. Most of the alluvial soil is derived from the sediments deposited by the rivers.  

Red Soil  

1. It is less fertile as it is deficient in phosphorus, nitrogen lime and humus.  

2. Most of the red soil has been formed due to weathering of ancient crystalline and metamorphic rocks.

Explanation:

Alluvial soils are highly fertile soils found mostly along the river basins and support a great variety of crops both kharif and rabi. Red soils are heavily leached soils and hence leave behind good amount of iron in the upper layer of soil profile.

4)It is more fertile and deep.

5) it is formed due to depositional activities carried out by the rivers.

Red Soil -

1) it is rich in iron content and is formed by the weathering of ancient crystalline and metaphors rock.

2) it is porus and friable in nature

3) red soils are heavily leached soil and and hence leave behind good amount of iron in the upper layer of soil profile.

4) red soil is not water retentive and less fertile.

5) this soil is formed as a result of weathering of rocks.
