Contour plowing, no-till planting, and planting trees to serve as wind buffers are all methods used to a. reduce erosion b. farm organically c. conserve water d. increase crop yields select the best answer from the choices provided. a b

Option (A)

Explanation:

Contour plowing is usually defined as an efficient technique for plowing that is carried along the elevation contours of the land in the hilly areas in order to reduce the effect of soil erosion. It also improves the drainage pattern and improves the quality of the water. No-till planting (farming) is a commonly used agricultural technique that does not involve the use of tillage, and enriches the fertility of the soil and also reduces the soil erosion effect. Afforestation is a process characterized by the planting of new plants and trees in order to reduce the effect of soil erosion, and also increases the fertility of the soil.

Thus, all these three processes are mainly implemented in order to reduce soil erosion, which usually takes place due to agents like wind and water.

Hence, the correct answer is option (A).
