Primary (Macro)‎ plant nutrients : nitrogen, phosphorus and potassium

Abstract EN

Eighteen essential elements that plants must have in order to grow properly, three Nutrient elements obtained from atmosphere through photosynthesis Hydrogen, Carbon and Oxygen.

Fifteen nutrient elements obtained from the soil are essential for proper crop development.

Each is equally important to the plant, yet each is required in very different amounts.

These differences have led to the grouping of these essential elements into three categories; primary (macro) nutrients (Nitrogen, Phosphorus and Potassium) secondary (macro) nutrients (Calcium, Magnesium and Sulfur) and micronutrients (Boron, Copper, Iron, Manganese, Zinc, Molybdenum, Chlorine, Cobalt and Nickel).
