A. They have less amount of nutrients as compared to fertilizers.
B. Manures are bulky and can’t be easily stored or transported.
C. Both A and B
D. None of the above

Answer 1

Hint: Manure are the organic substances which add nutrients to the soil and they also help to make the texture of soil good. The manure is considered better than the fertilizers. Fertilizers have chemicals in them, which harm the soil.

Complete answer:
A manure is a natural substance. It is obtained by the decomposition of animal wastes such as dung (gobar) of cattle and buffaloes and plant residue. A manure contains small essential plant nutrients such as phosphorus, nitrogen and potassium. They add a great amount of organic matter in the form of humus into the soil. Nutrients present in the manure are absorbed slowly by the crop plants, since manure is not soluble in water. Nutrients are locked inside the organic compounds of humus.

Manure is so heavy and bulky so it is inconvenient to store, transport, handle and apply to the crop. A manure is cheap and is prepared in rural areas or fields.
A manure is not nutrient specific and it tends to remove the general deficiency from the soil.

Disadvantages of a manure are that they have less amount of nutrients as we compared it with the fertilizers and also they are bulky and so hard to carry or transport from one place to another.

Hence, the correct answer is option (C).

Note: A fertilizer is nutrient specific, as we compare it to manure it can easily provide nutrients, phosphorus and potassium to the soil according to the need. Fertilizers are compact and concentrated so it is easy to store, transport and apply to the crop.
