Hint: As we already know, the type of soil that can develop in a warm temperature can be a moist climate, generally under mixed or deciduous forests. Such soil is mostly found in places like Central Africa, South America, South and Southeast Asia, India, China, Japan, and Australia. Many of the thin organic and organic mineral coverings commonly overlap a yellowish-brown leaching layer resting on the illuvium red layer. Most people say that such type of soil is obtained from crystalline rock.
Complete answer:
-Red soil is not very fertile soil because it is low in humus and nutrients. Red soil is difficult to cultivate as it has low water holding capacity.
-Chemical composition of the red soil is 90.47 percent non-soluble material, 3.61 percent iron, 2.9 percent aluminium, 1.01 percent organic matter, 0.70 percent magnesium, 0.56 percent lime, 0.30 percent carbon dioxide, 0.24 percent potash, 0.12 percent soda, 0.09 percent phosphorus, and 0.08 percent nitrogen.
-Red soil is deficient in magnesia, lime, nitrogen, phosphates, potash, and humus. Only the lowermost area of red soil is very fertile. The upper layer of red soil is porous and sandy. The red soil has a pH value of 4.5-6.5.
Hence, the correct answer is option B.
Additional Information:
-Red soil is the third-largest soil of India. It covers approximately 3.5 lakhs sq.km area.
-Soil is red because iron present within the soil gets more readily oxidized due to the high oxygen content. Due to this soil develops a rusty colour. The presence of organic matter also darkens the colour.
-Wheat, cotton, rice, beans, oilseeds, millets, and fruits are some crops that grow in red soil.
Note:
Red soil is not very fertile soil as it is low in humus and nutrients. Red soil is a soil that expands in warm conditions, moist climate under mixed or deciduous forest. Red soil is retaining the thin organic and organic mineral layers, which are made to overlay a yellowish-brown leached layer resting on the illuvium red layer. Red mud is deficient in magnesium, lime, nitrogen, phosphates, potash, and humus. The red soil has a pH value, which varies between 4.5 to 6.5. People say that the colour of this soil is red due to the posture of iron at a high proportion.
