Question 3

Laterite soils are extensively found in the midland regions of Kerala. Considering their formation process and typical properties, which of the following statements accurately describes a key characteristic and its implication for agriculture in the state?

Accepted Answer

C. They are characterized by a high content of iron and aluminum oxides, are generally acidic, and have low fertility due to intense leaching of basic nutrients, requiring liming and fertilization for good yields. — Laterite soils form under hot, humid tropical conditions through intense leaching, which removes silica and most basic cations, leaving behind iron and aluminum oxides. This process makes them acidic and poor in essential plant nutrients and organic matter. Consequently, farmers in Kerala often need to apply lime to neutralize acidity and add fertilizers to improve soil fertility for successful cultivation.

Answer

A. They are highly fertile due to rich organic matter content and excellent water retention, supporting intensive farming without significant amendments.

Answer

B. They are formed through the deposition of river sediments, making them deep, well-aerated, and naturally rich in all macro-nutrients.

Answer

D. They possess a high cation exchange capacity and neutral pH, which allows for a wide variety of crops to thrive naturally even in dry conditions.
