Organic fertilizers are fertilizer compounds that contain one or more kinds of organic matter. The ingredients may be animal or vegetable matter or a combination of the two. It is possible to purchase commercial brands of organic rich fertilizer as well as prepare organic fertilizer at home by building a compost heap.
In many agriculture areas, pollution of groundwater courses with synthetic fertilizers and pesticides is a major problem. As the use of these is prohibited in organic agriculture, they are replaced by organic fertilizers (e.g. compost, animal manure, green manure) and through the use of greater biodiversity (in terms of species cultivated and permanent vegetation), enhancing soil structure and water infiltration.
