Question

Why do we add a mixture of fertilizers and manure

Answer 1

As we know that, fertilizers are made up of chemicals and manure are made up of bio degradable substances. If we will add only fertilizers in the soil then it can harm the soil and plants. So, to maintain the fertility of soil and to get best results we add a mixture of fertilizers and manure.

Answer 2

Manures and fertilizers as a mixture help in conserving and enriching the fertility of the soil. By growing plants again and again on the same soil, the soil becomes deficient in nutrients and becomes infertile.Thus it is necessary to replenish the soil with these nutrients. This is why farmers add a mixture of fertilizers and manure.
