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.
Choose the correct answer from the options given below:
Analyzing Soil Statements for Falsity
The question asks to identify the false statement(s) about soil functions and protection. Let's analyze each statement:
Statement 1: Fertile Soil Properties
This statement accurately describes the role of fertile soil. It acts as a foundation for plant life by supplying essential nutrients, retaining water necessary for plant processes, and providing an anchorage for roots.
Therefore, Statement 1 is TRUE.
Statement 2: Vegetation and Soil Protection
This statement correctly highlights the importance of vegetation, tree cover, and forests. These elements play a critical role in preventing soil degradation and desertification by physically stabilizing the soil and maintaining vital water and nutrient cycling.
Therefore, Statement 2 is TRUE.
Statement 3: Grass, Erosion, and Biological Activity
This statement claims that grass on pasture lands cannot protect against soil erosion and inhibits soil biological activities. This is factually incorrect.
- Erosion Control: The root systems of grasses effectively bind soil particles together, significantly reducing soil erosion caused by wind and water.
- Biological Activity: Grasses contribute organic matter (through roots and decaying plant material) to the soil, which fuels and enhances soil biological activities (e.g., microbial decomposition, nutrient cycling).
Therefore, Statement 3 is FALSE.
Conclusion on False Statements
Based on the analysis, only Statement 3 is false. The question asks for the FALSE statement(s).
Correct Answer is Option 4: 3 only
Important Questions from Soils
- Which soil is acidic in nature and found in high rainfall areas?
The soil that is present over the piedmont plains such as Chos and Duars is
With reference to the different types of soil found in India, identify the pairs which is/are wrongly matched.
1. Submontane soil - These are formed by the deposition of eroded material and are found in the Tarai region stretching from Jammu and Kashmir to Assam.
2. Karewa soil - These are the lacustrine deposits found in the Kashmir valleys and Bhadarwah Valley.
3. Peaty and Marshy soil - These are typical soils of the monsoon climate characterised by seasonal rainfall and is deficient in organic matter.
4. Laterite soil - These soils are rich in humus and organic matter.
Choose the correct answer from the options given below:Match List I with List II.
List – I (Pedogenic Process) List – II (Description) A. Podzolization I. It is associated with humid cold mid-latitude climates and coniferous vegetation B. Laterization II. It is associated with soils found in tropical and subtropical environments C. Calcification III. It is associated with warm, semi-arid environments, usually in grassland vegetation where evapotranspiration exceeds precipitation D. Gleization IV. It is associated with poorly drained and water logged areas of cold climates and peat is found in the upper portion of the soil Which of the following features are associated with Regur Soils in India?
1. It develops on crystalline igneous rocks as a result of intense leaching.
2. It is rich in Iron, Potash and Phosphoric contents.
3. It is typically found in north-west region of Deccan plateau and made up of lava flows.
4. It is rich in calcium carbonate, magnesium, potash and lime.
