A. Nitrogen and iron oxide
B. Iron oxide and nitrogen
C. Phosphorus and iron oxide
D. Iron oxide and boron

Answer 1

Hint:-Red soil is found in regions of igneous and metamorphic rocks. Its red color is due to ferrous and other humus content. The soil is porous and fertile. This type of soil is found in Goa, Tamilnadu, Andhra Pradesh, Odisha and Jharkhand. Tobacco, groundnut, ragi etc. can be grown in red soil.

Complete Answer:-The shade of red soil goes from red to brown, chocolate, yellow, dark, or here and there even dark. Red soil contains a high level of iron substance, which is answerable for its tone. This dirt is inadequate in nitrogen, humus, phosphoric corrosive, magnesium, and lime yet genuinely wealthy in potash, with its pH going from unbiased to acidic.
It is framed by the enduring of antiquated translucent and transformative rocks, especially corrosive stones and gneisses, quartzitic rocks, and feldspathic rocks. Artificially, red soil is siliceous and aluminous, with free quartz as sand, yet is wealthy in potassium, going from sand to dirt with the greater part being loamy.
The lowermost territory of red soil is dull in shading and prolific, while the upper layer is sandy and permeable. Along these lines, appropriate utilization of manures and water systems yields high creation of cotton, wheat, rice, beats, millets, tobacco, oil seeds, potatoes, and natural products.

Note:- Roughly 10.6% of the complete geological region of India is covered by red soil, including Tamil Nadu, portions of Karnataka, southeastern Maharashtra, eastern Andhra Pradesh and Madhya Pradesh, Orissa, Chhattisgarh, Chota Nagpur (Jharkhand), south Bihar, West Bengal (Birbhum and Bankura), Uttar Pradesh (Mirzapur, Jhansi, Banda, and Hamirpur), Aravallis, eastern Rajasthan, Assam, Nagaland, Manipur, Mizoram, Tripura, and Meghalaya
