Introduction:
India is known for its diverse soil types, and alluvial soils are one of the most prominent soil types found in the country. Alluvial soils are formed by the deposition of sediments brought by rivers and are known for their high fertility.
Explanation:
Let's analyze each statement to determine their correctness:
1. These are mostly clay soils and form deep cracks during the dry season.
This statement is correct. Alluvial soils are predominantly composed of clay and silt. Due to their fine particle size, they have good water-retaining capacity. However, during the dry season, they tend to shrink and form deep cracks.
2. Usually, they are very productive soils.
This statement is correct. Alluvial soils are highly fertile and known for their productivity. They are rich in minerals and organic matter, making them suitable for a wide range of crops. The regular deposition of sediments by rivers replenishes the nutrients, making these soils highly productive.
3. These soils occur at high elevations as well as low elevations.
This statement is incorrect. Alluvial soils are primarily found in the plains and low-lying areas. They are formed by the deposition of sediments carried by rivers and streams in these regions. High elevations are more likely to have rocky and mountainous terrain, which is not conducive to the formation of alluvial soils.
4. Many of these soils are deficient in nitrogen, humus, and phosphorus.
This statement is correct. While alluvial soils are generally fertile, some regions may have deficiencies in certain nutrients. Nitrogen, humus, and phosphorus deficiencies are common in alluvial soils. However, these deficiencies can be addressed through proper fertilization and soil management practices.
Conclusion:
Based on the analysis, statement 1 and 2 are correct, while statement 3 and 4 are incorrect. Therefore, the correct answer is option 'B' - 2 and 4. Alluvial soils are mostly clay soils that form deep cracks during the dry season. They are highly productive but can be deficient in certain nutrients like nitrogen, humus, and phosphorus.
