Contour cultivation is one of the following measures of soil conservation

Correct option is A

Contour Cultivation:

1. • Definition: Plowing and planting along the contour lines of a slope.

   • Main Benefits:

     • Reduces soil erosion.

     • Improves water infiltration.

     • Enhances soil moisture conservation.

     • Minimizes runoff and nutrient loss.

• Mechanical :

  • Mechanical soil conservation methods involve engineering structures like terraces, bunds, and check dams to control erosion.

  • • Terracing (constructing step-like fields on slopes).

    • Contour bunding (earthen embankments along contour lines).

    • Check dams (small barriers in streams to slow water flow).

• Forestry :

  • Forestry-based soil conservation methods include afforestation, agroforestry, and shelterbelts to protect soil from wind and water erosion.

  • • Planting trees and shrubs to stabilize the soil.

    • Windbreaks and shelterbelts to reduce wind erosion.

    • Agroforestry (growing trees alongside crops).
