Question

Why is the combination of Manures
and fertilizers better than
using either one​

Answer 1

if we use a combination of manuals and fertilizers then we can get the benefits of both and if you just use a man or a fertilizer then we can't get the use of it we can get a use of only one thing

Answer 2

Manure is made up of environmental friendly materials so it will maintain the fertility of soil whereas fertilizer are made up of chemicals so they will reduce the fertility of soil. If we only use fertilisers it can harm the fertility of the soil, whereas if we only use manure the crops might not get enough nutrition for growth. Therefore, using both in correct quantities is the best way!!
