Soils

Choose the Correct Answer

Correct Answer : Option b

Explanation
Statement 1 is correct: Laterite soils are indeed formed by the intensive weathering of parent rock over a long period, typically in tropical climates with high rainfall. The weathering process leeches away most minerals, leaving behind residual materials such as iron and aluminum oxides.

Statement 2 is not correct: Laterite soils are generally poor in lime, potash, and nitrogen. These soils often lack the essential nutrients required for good fertility. They are rich in iron and aluminum, but not in nutrients like lime, potash, or nitrogen. Therefore, this statement is not correct.

Statement 3 is correct: Leaching is the process by which minerals are washed away from the soil due to heavy rainfall. Laterite soils suffer from intensive leaching, which results in a loss of nutrients, making them less fertile and not ideal for growing most crops without the addition of fertilizers.

Statement 4 is correct: Despite their general low fertility, laterite soils can be suitable for plantation crops like tea, coffee, rubber, and cinchona, especially when enriched with organic matter and fertilizers. These crops are often grown in areas with laterite.
