Any natural or manufactured material, which contains at least 5% of one or more of the three primary nutrients (N, P2O5, K2O) can be called fertilizer. Industrially manufactured fertilizers are called mineral fertilizer. There are organic fertilizers and inorganic fertilizers. The organic fertilizers are made of enriched organic matter of plants and animals and inorganic nitrogenous fertilizers are synthesized chemically.
