Question

Which of the following soil types is predominant in Kerala and is especially dominant in the Midland Region?

• A. Black Soil
• B. Alluvial Soil
• C. Laterite Soil
• D. Red Soil

Answer 1

Answer:

C. Laterite Soil

• Correct Answer: Option C - Laterite Soil

• Laterite soil is the predominant soil type in Kerala, particularly in the Midland region. This soil type is characterized by its reddish color due to high iron and aluminum content, formed through a process called laterization where silica is leached away by heavy rainfall, leaving behind iron and aluminum oxides.

• The Midland region of Kerala, which occupies about 42% of the state's total land area, lies between the highlands and the coastal lowlands. This region experiences high rainfall and tropical climate conditions that are ideal for laterite soil formation. The laterite soil in this region has undergone significant weathering due to the monsoon climate.

• While laterite soil is not naturally very fertile, it has good drainage properties and, with proper management practices including addition of organic matter and fertilizers, supports the cultivation of various crops including rubber, coconut, cashew, and various spices for which Kerala is famous.
