| The term ‘fertilizer’ is used for any material, organic or inorganic, natural or synthetic, that supplies plants with one or more of the nutrients necessary for plant growth and optimum yield. Organic fertilizers are natural materials of either plant or animal origin, which are able to supply one or more nutrients to plants. Inorganic (or mineral) fertilizers are fertilizers mined from mineral deposits, or industrially manufactured through chemical processes using mineral feedstocks. | ||
