A1 & 2

B2 & 3

C1 & 3

DAll are correct

Answer:

A. 1 & 2

Read Explanation:

  • Correct Answer: Option A) 1 & 2

  • Forest soils are generally acidic in hill areas - This statement is correct. Forest soils, especially in hill areas, tend to be acidic due to the decomposition of leaf litter and other organic materials. The decomposition process releases organic acids that lower the pH of the soil.

  • Forest soils are rich in humus due to leaf litter - This statement is also correct. The abundant leaf fall in forests creates a thick layer of organic matter that decomposes to form humus. This humus enriches the soil with nutrients and improves its structure and water-holding capacity.

  • Forest soils are ideal for cereals without any treatment - This statement is incorrect. Forest soils, while rich in organic matter, often have certain limitations for cereal cultivation without treatment. They can be too acidic for many cereal crops, may lack certain essential nutrients in the right proportions, and often require adjustments (such as lime application to reduce acidity) before being suitable for cereal cultivation.
