Essential macronutrients are the primary nutrients that plants use in large amounts to
grow and produce. Each macronutrient plays a unique and essential role in promoting
plant growth, vigour, and flowering. A shortage in any of them leads to adverse effects.
Plants are comprised of 60 chemical elements, 16 of which are essential. Carbon,
hydrogen, and oxygen are extracted from the air. The remaining 13 are extracted from

and is directly related to plant growth.
It is indispensable for photosynthesis activity and chlorophyll formation.
Phosphorus — transports and stores energy for growth, flowering, and seed formation.
Potassium — regulates water and the transport of the plant’s reserve substances. It
increases photosynthesis capacity, strengthens cell tissue, and activates the absorption of
nitrates. Potassium stimulates flowering and the synthesis of carbohydrates and enzymes.
Calcium — necessary for respiration, cell division, and cell stabilisation. Calcium
contributes to mineral retention in the soil and to the transportation of such minerals.
Magnesium — constitutes the core of the chlorophyll molecule and is therefore essential for
photosynthesis. Magnesium promotes the absorption and transportation of phosphorus
and iron. It contributes to the storage of sugars within the plant. Magnesium performs the
function of an enzyme activator and activates more enzymes than any other nutrient.
Sulfur — It is necessary for performing photosynthesis and intervenes in both protein
synthesis and tissue formation. Sulfur is fundamental in the metabolising of nitrogen.
