Which among the following are mechanical method of soil conservation ?...
Stubble Mulching is not a mechanical method, but a crop management technique that helps in soil conservation. The soil conservation measures are mainly of two types: (a) crop management, and (b) providing mechanical protection. Techniques like stubble mulching, in which the roots, stems and leaves are left over in the agricultural fields after harvesting, help to conserve soil.

Which among the following are mechanical method of soil conservation ?...
Explanation:
Mechanical methods of soil conservation:
- Mechanical methods of soil conservation involve physically altering the land to reduce erosion and improve soil health.
- These methods are typically labor-intensive but can be effective in preventing soil degradation.
1. Bunding:
- Bunding involves building small embankments or ridges along the contour of the land to slow down water runoff and prevent soil erosion.
- This helps to trap sediment and water, allowing for better infiltration and reducing the risk of soil erosion.
2. Terracing:
- Terracing is a method of creating level areas on sloping land by building a series of steps or platforms.
- This helps to reduce the speed of water runoff, prevent soil erosion, and improve water retention in the soil.
3. Contour farming:
- Contour farming involves planting crops along the contour of the land to reduce the speed of water runoff and prevent soil erosion.
- This method helps to retain soil moisture, improve soil structure, and reduce the risk of landslides.
4. Stubble mulching:
- Stubble mulching involves leaving crop residues on the soil surface after harvest to protect the soil from erosion and improve soil health.
- This method helps to reduce water runoff, improve soil structure, and increase organic matter content in the soil.
Therefore, among the given options, bunding, terracing, and contour farming are mechanical methods of soil conservation as they involve physical alterations to the land to prevent soil erosion and improve soil health. Stubble mulching, on the other hand, is a biological method of soil conservation that focuses on improving soil health through the use of crop residues.
