Question

why organic manure is considered better fertilizers ? Give three reasons why grains are properly dried in the sun before storage ?​

Answer 1

If freshly harvested grains are stored without drying they may get spoilt or attacked by microorganisms, loosing their germination capacity. Hence, before storing them the grains are properly dried in the sun to reduce moisture in them. This prevents the attack by insects, pests, bacteria and fungi.

Answer 2

Organic manure is considered better than fertilisers because:
1. Organic manure does not cause water pollution while fertilisers does.
2. Organic manure supply organic materials to soil and makes the soil fertile, while fertilisers does not.
3. Organic manure makes the soil moist and increase the water holding capacity while fertilisers do not.
