Zorluk: KolayState Economy, Agriculture, and Natural Resources

Which of the following statements regarding agricultural soils and mineral resources of an Indian state are correct?

  1. Black soil (Regur) is rich in clay content and possesses high moisture retention capacity suitable for cotton cultivation.Cevap
  2. B
    Alluvial soils naturally contain high concentrations of nitrogen and organic humus.
  3. Dharwar rock formations host major metallic mineral reserves such as iron ore and manganese.Cevap
  4. D
    Laterite soils are formed under cold, arid conditions with negligible annual rainfall.

Cevap

The correct statements are that black soil (Regur) is rich in clay content with high moisture retention suitable for cotton, and Dharwar rock formations host major metallic mineral reserves such as iron ore and manganese.
Black soil's high clay fraction provides high water retention beneficial for cotton growth, while Dharwar geological formations are classic metallic mineral belts containing extensive deposits of iron ore and manganese.

Adım Adım Çözüm

1
Evaluate the soil characteristics for cotton cultivation
Black soil (Regur) is rich in clay, retains moisture effectively, and is ideal for cotton farming.
Verify fundamental agricultural soil properties.
2
Examine the chemical composition of alluvial soils
Alluvial soil is deficient in nitrogen and humus despite being rich in potash.
Identify common nutrient deficiencies in river-deposited soils.
3
Assess mineral distribution across geological rock systems
Dharwar rock systems are well-known repositories of metallic minerals like iron ore and manganese.
Confirm major mineral geological formations.
4
Determine the formation conditions of laterite soil
Laterite soils form in high temperature and high rainfall zones due to leaching, not cold arid climates.
Check climate requirements for soil leaching processes.
