Which one of the following is found in appreciable amount in Laterite soil in India?

The correct answer is Phosphate.

Key Points

• Laterite soils are rich in iron oxide and aluminum.
• They form in hot and wet tropical areas where intense weathering occurs.
• In India, Laterite soils are predominantly found in states like Kerala, Karnataka, Tamil Nadu, Madhya Pradesh, and the hilly regions of Odisha and Assam.
• Phosphate is found in appreciable amounts in Laterite soil, making it suitable for crops like tea, coffee, and cashew.

Additional Information

• Formation of Laterite Soil:
  • Laterite soil forms through the process of laterization, which involves the leaching of silica and other soluble minerals, leaving behind oxides of iron and aluminum.
  • This process is common in tropical regions with high rainfall and temperatures.
• Agricultural Suitability:
  • Due to its high iron and aluminum content, laterite soil is generally not very fertile for traditional agriculture.
  • However, it is suitable for specific crops like tea, coffee, rubber, coconut, and cashew.
• Challenges with Laterite Soil:
  • Laterite soil can become very hard and compact when dry, making it difficult to till.
  • It is prone to erosion due to its loose top layer.
• Soil Management:
  • To improve fertility, laterite soils often require the addition of organic matter and fertilizers.
  • Proper irrigation and drainage systems are essential to manage moisture levels and prevent erosion.
