The correct answer is: C) Moderate
Black soils are a type of soil that is rich in organic matter and clay. They are found in tropical and subtropical regions around the world. Black soils are known for their high water-holding capacity, which makes them ideal for growing crops.
The water-holding capacity of black soils is due to the presence of clay particles. Clay particles are very small and have a large surface area. This allows them to hold a lot of water. The organic matter in black soils also helps to improve their water-holding capacity.
Black soils are a valuable resource for agriculture. They are able to support a wide variety of crops. However, black soils can also be prone to erosion. This is because they are relatively soft and can be easily washed away by water.
To protect black soils from erosion, it is important to practice good land management. This includes planting cover crops, using no-till farming practices, and avoiding overgrazing.
Here is a brief explanation of each option:
- Option A: Very low. This is incorrect because black soils have a moderate water-holding capacity.
- Option B: Low. This is incorrect because black soils have a moderate water-holding capacity.
- Option C: Moderate. This is the correct answer because black soils have a moderate water-holding capacity.
- Option D: High. This is incorrect because black soils have a moderate water-holding capacity.
