What is provided by fertilizers? What will they feed a lawn or landscape? Fertilizers typically provide several different nutrients in varying proportions.
The six macronutrients in most fertilizers are nitrogen (N), phosphorus (P), potassium (K), calcium (Ca),magnesium (Mg), and sulfur (S). There are also eight micronutrients including, boron (B), chlorine (Cl), copper (Cu), iron (Fe), manganese (Mn),molybdenum (Mo), zinc (Zn) and nickel (Ni).
Macronutrients are consumed in larger quantities and present in plant tissue in higher quantities. Micronutrients, on the other hand, are consumed in smaller quantities these are only present in plant tissue in parts per million. The only other three structural elements required by all plants are carbon, hydrogen, and oxygen. These nutrients are supplied by steady watering and through carbon dioxide in the atmosphere.
