C. Rock dam
D. Planting grass​

Answer 1

Answer:

The moisture of soil can be retained by the process of planting grass .

Answer 2

The moisture of soil can be retained by the process of Mulching.

Mulching:

• Mulching is a process in which plants are covered with a layer of dried straw or fallen leaves, conserves soil moisture, and keeps the temperature surrounding the roots at 25-32 degrees Celsius, allowing microorganisms to do their work.
• Between plants, a layer of organic materials such as straw covers the barren ground and helps to keep the soil moist.

Rock Dam:

• Rocks are heaped to slow down water flow while also preventing gullies and soil erosion.

Counter Barrier:

• Stones, grass, and soil are utilized to form barriers following contours. Water is collected in trenches in front of the barriers.

Planting grass:

• Planting grass can help to conserve soil but not soil moisture.

So, soil moisture can only be retained through Mulching.
