Which of the following options is true about manure ?
A. lt enhances the water-holding capacity of soil.
B. It makes the soil non-porous to stop exchange of gasses.
C. lt increases the number of friendly microbes.
D. It improves the texture of the soil.

Correct option is C

The correct answer is A, C and D.
• A (It enhances the water-holding capacity of soil): This is true. Manure increases the organic matter content of the soil, which improves its ability to hold water.
• B (It makes the soil non-porous to stop exchange of gasses): This is false. Manure actually improves the drainage and aeration of the soil by creating larger pore spaces.
• C (It increases the number of friendly microbes): This is true. Manure provides a food source for beneficial microbes, which improve the decomposition of organic matter and release nutrients for plants.
• D (It improves the texture of the soil): This is true. Manure adds organic matter, which makes the soil more crumbly and easier to work with.
Therefore, only options A, C, and D are true about manure.
