1. High moisture-retaining capacity, often developing deep cracks during dry hot weather.
2.Ideal for tea and apple cultivation due to high fertility and cold climate preference.
3. Rich in lime, iron, magnesia, and alumina, but poor in phosphoric contents.
Which of the above characteristics are primarily associated with Black Soils?
Black Soils Characteristics Explained
This question asks us to identify which of the given characteristics are typically associated with Black Soils (also known as Regur soil). Let's analyze each characteristic individually:
Characteristic 1: Moisture Retention and Cracking
- Statement: High moisture-retaining capacity, often developing deep cracks during dry hot weather.
- Analysis: Black Soils are famous for their ability to retain moisture. This is due to their fine texture (clayey nature). When these soils become very dry during hot weather, they shrink and develop deep, wide cracks. This characteristic is a hallmark of Black Soils.
- Verdict: This statement is associated with Black Soils.
Characteristic 2: Crop Suitability and Climate
- Statement: Ideal for tea and apple cultivation due to high fertility and cold climate preference.
- Analysis: Black Soils are highly fertile and are excellent for growing crops like cotton, groundnuts, and millets. However, they are typically found in warmer regions, particularly the Deccan Plateau. Tea and apple cultivation usually thrive in well-drained, acidic soils found in hilly or mountainous regions with cooler climates (like Assam, Darjeeling, or Himachal Pradesh). Black Soils generally do not prefer cold climates and are not the primary choice for tea and apple cultivation.
- Verdict: This statement is NOT primarily associated with Black Soils.
Characteristic 3: Mineral Composition
- Statement: Rich in lime, iron, magnesia, and alumina, but poor in phosphoric contents.
- Analysis: Black Soils are indeed known to be rich in essential minerals like lime, iron, magnesia, potash, and alumina. However, they are generally deficient in crucial nutrients like phosphorus and nitrogen, and sometimes humus.
- Verdict: This statement is associated with Black Soils.
Conclusion on Black Soil Traits
Based on the analysis, characteristics 1 and 3 accurately describe Black Soils:
- High moisture-retaining capacity and deep cracking are key features.
- Their mineral composition is rich in lime, iron, magnesia, and alumina, though often poor in phosphorus.
Characteristic 2 relates more to soils found in different climatic and topographical conditions.
Therefore, the characteristics primarily associated with Black Soils are the first and the third ones.

Which of the following statements regarding Soil is/are FALSE?
1. Fertile soil supports plant growth by providing plants with nutrients, acting as a water holding body and serving as the substrate to which plants anchor their roots.
2. Vegetation, tree cover and forest prevents soil degradation and desertification by stabilizing the soil, maintaining water and nutrient cycling.
3. Grass found on pasture lands cannot protect the soil against soil erosion and also inhibits the soil biological activities.
