Zorluk: ZorState Economy, Agriculture, and Natural Resources

Consider the following statements regarding the agricultural zoning and natural resource distribution within a state's economy:

1. Black soil (Regur) tracts in the basaltic plateau region predominantly support cotton and sugarcane cultivation, forming the backbone of the state's agro-processing sector.
2. The Dharwar geological formations in the southern district belt contain major iron ore and manganese deposits that contribute substantially to the mining sector's Gross State Value Added (GSVA).
3. Laterite soil zones in the coastal high-rainfall belt are highly fertile and primarily utilized for intensive canal-irrigated wheat farming.

Which of the statements given above are correct?

  1. 1 and 2 onlyCevap
  2. B
    2 and 3 only
  3. C
    1 and 3 only
  4. D
    1, 2 and 3

Cevap

Statements 1 and 2 are correct, while statement 3 is incorrect.
Statements 1 and 2 correctly describe the agricultural role of moisture-retentive black soils in supporting cash crops (cotton and sugarcane) and the economic contribution of metallic mineral deposits in Dharwar rock formations to the state's mining GSVA. Statement 3 is incorrect because laterite soils are heavily leached, acidic, and nutrient-deficient, making them unsuitable for intensive wheat farming.

Adım Adım Çözüm

1
Evaluate Statement 1 regarding agricultural cropping patterns on basaltic black soils.
Statement 1 is correct. Basalt-derived black soil (Regur) retains high moisture, making it ideal for rainfed and irrigated cash crops like cotton and sugarcane, which feed the state's agro-processing industries.
Soil texture and mineral composition determine crop suitability and regional agro-industrial linkages.
2
Evaluate Statement 2 regarding mineral resource distribution in Dharwar rock systems.
Statement 2 is correct. Dharwar geological formations are famous for metallic mineral deposits such as high-grade iron ore and manganese, which generate significant revenue and mining Gross State Value Added (GSVA).
Geological rock systems correlate directly with specific mineral belts and economic sector output.
3
Evaluate Statement 3 regarding laterite soil fertility and crop suitability.
Statement 3 is incorrect. Laterite soils develop under high temperature and heavy rainfall where intense leaching washes away silica, leaving behind iron and aluminum oxides. These soils are acidic, poor in organic matter, and generally unsuited for intensive wheat cultivation; they are instead used for plantation crops such as cashew and rubber.
Pedological leaching mechanisms reduce soil fertility in laterite tracts.
