Explanation:
1. Rich in humus:
- Forest soils are typically rich in organic matter, including humus, which is formed from the decomposition of plant and animal materials.
- Humus helps to improve soil structure, fertility, and moisture retention, making forest soils ideal for supporting diverse plant and animal life.
2. Deficient in phosphorous and potash:
- While forest soils are generally nutrient-rich due to the presence of organic matter, they can be deficient in certain essential nutrients like phosphorous and potash.
- Phosphorous and potash are important for plant growth and development, and their deficiency can limit the productivity of forest ecosystems.
Conclusion:
Both statements are correct. Forest soils are rich in humus but may be deficient in phosphorous and potash, highlighting the importance of nutrient management in forest ecosystems.

Consider the following statements about forests soils :1. They are ric...
Forest soils are a vital component of forest ecosystems. They are formed by the accumulation of dead organic matter, including leaves, branches, and other plant debris. These soils have unique characteristics due to the specific properties of forest vegetation.
Statement 1: They are rich in humus
Humus is a dark, organic material that forms in soil when plant and animal matter decays. It is a key component of forest soils and provides many benefits, including:
- Improving soil structure and water-holding capacity
- Enhancing nutrient retention and availability
- Promoting soil microbial activity
Therefore, statement 1 is true.
Statement 2: They are deficient in phosphorous and potash
Phosphorous and potash are essential nutrients for plant growth. However, forest soils are often deficient in these nutrients due to the following reasons:
- Forest vegetation tends to take up and retain these nutrients, making them less available in the soil.
- Forest soils are often acidic, which can limit nutrient availability.
- The slow rate of decomposition in forest ecosystems can result in a limited supply of nutrients.
Therefore, statement 2 is also true.
Conclusion
As both statements are true, the correct answer is option D, neither 1 nor 2. Forest soils are rich in humus but are often deficient in phosphorous and potash.

Consider the following statements about forests soils :1. They are ric...
Forest soils are the soils that are found under forests. They are different from other soils in terms of their characteristics and composition. Let's discuss the given statements:
1. They are rich in humus:
- Humus is the organic component of soil, formed by the decomposition of leaves and other plant material by soil microorganisms.
- Forest soils are rich in humus because of the continuous supply of organic matter from the litter of trees and other plants.
- Humus helps in improving the soil structure, water holding capacity, and nutrient availability in the soil.
2. They are deficient in phosphorous and potash:
- Potash (K) and phosphorus (P) are two essential nutrients required for plant growth.
- Forest soils are generally low in these nutrients because they are not easily available in the soil.
- The nutrients get locked up in the organic matter and are slowly released as the organic matter decomposes.
- However, the absence of these nutrients does not necessarily mean that the forest soils are infertile. The plants in the forest have adapted to these conditions and are able to grow and thrive.
Therefore, the correct answer is option 'D' i.e. neither 1 nor 2. While forest soils are rich in humus, they are not necessarily deficient in phosphorous and potash. It depends on the specific conditions of the soil and the forest ecosystem.
