Question

Which of the following is correct about the Laterite soil?

Options

• It is the residual soil.

• It is formed by leaching due to tropical rains.

• Humus content of the soil is removed by bacteria.

• All of the above.

Answer 1

All of the above.

Explanation:

• (a) It is residual soil: Laterite soil is formed in situ, which develops from the weathering of rocks in the same place.
• (b) It is formed by leaching due to tropical rains: The heavy rainfall in tropical regions causes intense leaching, which washes away soluble nutrients from the soil.
• (c) Humus content of the soil is removed by bacteria: The warm, humid conditions of tropical areas accelerate the activity of bacteria, which decompose organic matter, reducing the humus content in the soil.
