Q. Consider the following statements regarding the soils developed under grassland ecosystems:

1. The rainfall in grasslands is inadequate, thereby preventing excessive leaching of mineral nutrients.
2. The abundant humus and partially decomposed organic materials in grassland soils enhance their water retention capacity.

Which of the above statements is/are correct?
Answer: Both 1 and 2
Notes: Both statements are correct. Grassland soils, such as Mollisols, are among the world’s most fertile due to moderate rainfall limiting nutrient leaching and the continuous addition of organic matter from dense grass roots. This results in high humus content, which improves soil structure and water retention, making them highly productive for agriculture.
