Answer 1

The correct answer is 3 and 4.

Methodology to maintain soil fertility, prevent soil erosion and exhaustion, and improve the degraded condition of the soil is known as Soil Conservation.
Some methods to conserve soil are as follows-
- Crop Rotation - is a practice in which different crop is cultivated on a piece of land each year, it helps to conserve soil fertility.
- Contour Ploughing - Ploughing parallel to the contours of a hill slope to form a natural barrier for water to flow down the slope
- Contour Bunding - involves the construction of banks along with the counters, it controls the flow of water and reduces soil erosion.
- Intercropping - Different crops are grown in alternate rows to protect soil erosion.
Other methods are-Windbreaks, Sand Fence, Rock dam, terrace farming, Mulching, etc.
While Overgrazing and shifting cultivation enhances soil degradation.
