Chemical fertilizers are manufactured chemicals designed to give a boost to plant growth and supply nutrients that are lacking. Usually the most important of these are nitrogen. Nitrogen (N) is important for leaf growth. Phosphorous (P) is needed for root health. Potash (K) is used in flower development. These are the primary chemicals in "complete" fertilizers. Often, small amounts of other chemicals such as sulfur, iron, magnesium, also are included.
