Question

disadvantages of using manure and fertilisers​

Answer 1

Manure adds nutrients to the soil without affecting its fertility. It does not damage the crops and produces healthy plants. Fertilizers are chemicals which lower the fertility of the soil if used regularly. They also damage the crops and make them unhealthy for consumption.

Answer 2
