Answer 1

The correct option is B

adding manure and fertilizers

The correct option is B

Explanation for the correct option:

1. Adding manures and fertilizers will improve the fertility of the soil.
2. They increase the water-holding capacity of the soil.
3. They make the soil porous and facilitates the exchange of gases.
4. The texture of the soil improves.
5. The number of microbes increases in the soil.

Explanation for the incorrect option:

Option A

1. Overgrazing of animals will lead to reduce inputs of soil organic matter because less plant biomass is available as litter, which in turn, reduces soil organic matter, nutrients, and biotic activity.

Option C

Final answer Adding manures and fertilizers increase the soil fertility.
