Fertilizer – any substance that applied to land to encourage plant growth and produce higher crop yield. Fertilizers may be made from organic material—such as recycled waste, animal manure, compost, etc.—or chemically manufactured. Most fertilizers contain varying amounts of nitrogen, phosphorus, and potassium. In the United States, it estimated that as much as 25% of fertilizer carried away as runoff. Fertilizer runoff has contaminated ground water. For example, some farmers use up to 40% more fertilizer than they need. See also Pesticides.
