Which of the following soil types becomes less fertile due to the intense leaching caused by tropical rains?

Answer Details

Tropical rains can cause intense leaching, which is the process of nutrients being washed away from the soil. This leaching can have a significant impact on soil fertility. Out of the given options, the soil type that becomes less fertile due to intense leaching caused by tropical rains is laterite soil.

Laterite soil is formed in areas with high temperatures and heavy rainfall, such as tropical regions. It is usually found in regions with a tropical monsoon climate, such as parts of India, Southeast Asia, and parts of Africa.

Because of the intense rainfall in these regions, laterite soil experiences a high degree of leaching. The heavy rainwater carries away the essential nutrients from the soil, making it less fertile over time. These nutrients include vital elements like nitrogen, phosphorus, and potassium, which are crucial for plant growth. As a result of intense leaching, laterite soils can become impoverished and low in nutrients.

This can pose challenges for agriculture as plants need these nutrients to thrive. Therefore, it is important for farmers in such regions to practice appropriate soil management techniques, such as using organic fertilizers or crop rotation, to replenish and maintain the fertility of laterite soil.
