describe red & yellow soil on the basis of composition, distribution, formation and suitability of crops.
Answers
Explanation:
The fine-grained red and yellow soils are normally fertile, whereas coarse-grained soils found in dry upland areas are poor in fertility. Have a porous and friable structure. They are generally poor in nitrogen, phosphorous and humus. These soils are airy and need irrigation for cultivation.
Answer:
Red and Yellow Soils
Locally called ‘Chalka’ in Andhra Pradesh.
Formation: These are derived from granites, gneisses and other metamorphic rocks —> Zonal Soils. These are formed under well-drained conditions.
Areas: Along the piedmont zone of the Western Ghat, a long stretch of area is occupied by red loamy soil. Yellow and red soils are also found in parts of Orissa and Chattisgarh and in the southern parts of the middle Ganga plain. They encircle the black cotton soil zone.
Soil Colour: The soil develops a reddish colour due to a wide diffusion of iron in crystalline and metamorphic rocks. It looks yellow when it occurs in a hydrated form. Often, their upper layer is red and the lower layer is yellow.
Soil Texture: Varies from sand to clay and loam.
Other Characteristic Features:
The fine-grained red and yellow soils are normally fertile, whereas coarse-grained soils found in dry upland areas are poor in fertility.
Have a porous and friable structure.
They are generally poor in nitrogen, phosphorous and humus.
These soils are airy and need irrigation for cultivation.
Intense leaching is a menace in these soil areas.
Suitable Crops: In places where irrigation facilities are available, the crops cultivated are wheat, cotton, pulses, tobacco, millets, oilseeds, potato, maize, groundnut and orchards
