Fertilisers are rich in particular nutrients. Hence any soil deficiency in a particular nutrient can be rectified. The yield of crops also becomes better. But excessive use of fertilisers makes soil less fertile. Further, fertilisers are a source of water pollution, as they leach into the soil
The main difference between both is that manure is a natural or an organic substance obtained by the decomposition of plant and animal wastes.whereas fertilisers are inorganic salts.
