Show answer & explanation
Correct answer: A
Answer: The statements that manure is an organic substance obtained from decomposition of plant or animal wastes and that it improves soil texture are correct. The statement that manure reduces the soil's water-retaining capacity is incorrect.
Manure is organic matter derived from the decomposition of plant and animal wastes. It supplies nutrients and supports soil biological activity.
Improves soil texture: added organic matter helps form stable aggregates, increases porosity and aeration, and enhances soil structure.
Increases water-holding capacity: organic matter in manure holds water and improves infiltration and moisture retention, so it does not reduce water retention.
Summary: therefore the correct combination is the statements describing manure as decomposed organic material and its role in improving soil texture; the claim that it reduces water retention is incorrect.
