1) Macronutrients (Macroelements or major elements): Nutrients which are required by plants in larger amounts (Generally present in the plant tissues in concentrations of 1 to 10 mg per gram of dry matter).
(2) The macronutrients include carbon, hydrogen, oxygen, nitrogen, phosphorous, sulphur, potassium, calcium, magnesium.
(3) Micronutrients (Microelements or minor elements or trace elements):Nutrients which are required by plants in very small amounts, i.e., in traces (equal to or less than 0.1 mg per gram dry matter).
(4) The micronutrients include iron, manganese, copper, molybdenum, zinc, boron and chlorine. Recent research has shown that some elements, such as cobalt, vanadium and nickel, may be essential for certain plants.
