Fertilizer is any organic or inorganic material of natural or synthetic origin that is added to a soil to supply one or more plant nutrients essential to the growth of plants and turf. The composition of fertilizers includes micro and macro elements. Fertilizer is available in many different forms. Most of the old formulations of fertilizers were all chemical but as the world has become more environmentally friendly, so we have realized the benefits of using organics and organically enriched fertilizers. Grasses and Greens supply a range of chemical, organic and organically enriched fertilizers.
