What are fertilizers?
You can think of fertilizers as plant food. Fertilizers are combinations of the nutrients that plants must have to grow, in a form that they can use. The main nutrients in fertilizer are three essential elements: Nitrogen, Phosphorous and Potassium, often referred to as N-P-K. There are a variety of “trace” minerals such as copper, manganese, zinc and boron that are also necessary for normal plant growth. All plant nutrients, whether found in organic or mineral fertilizers, are identical, but mineral fertilizers have the advantage of concentration and nutrients can be blended to meet specifications. Thus, mineral fertilizers can be designed to meet the nutritional needs of specific plants and soils.
