Solution
The correct option is B 1, 2 and 3
Crop rotation, contour cultivation, stubbles mulching are some methods which are effectively used to control soil erosion. It is an agronomic measure of soil conservation. It minimizes evaporation and increases the retention of moisture and nutrients. It also improves the physical condition of soil. It protects soil from wind and water erosion. Thus, the correct answer is '1, 2 and 3.'
