Nitrogen
Essential for protein synthesis and chlorophyll formation. Promotes leafy growth.
Phosphorus
Important for energy transfer as it is a part of ATP; critical for root development.
Potassium
Regulates osmotic balance, activates enzymes, and is important for resistance to drought and disease.
Calcium
Important for cell wall structure, cell division, and signalling.
Magnesium
Central component of chlorophyll molecule and is crucial for photosynthesis.
Sulfur
Integral for amino acids, proteins, enzymes, and vitamins. It also helps in chlorophyll formation.
Iron
Essential for the formation of chlorophyll and is necessary for many enzyme functions.
Boron
Required for cell wall formation and stability, and is involved in cell division and protein synthesis.
Copper
Functions as an enzyme cofactor and is necessary for chlorophyll synthesis.
Manganese
Plays a role in chlorophyll production, enzymatic reactions, and nitrogen assimilation.
Molybdenum
It's crucial for enzyme systems involved in nitrogen fixation and assimilation.
Zinc
Important for enzyme systems that regulate early growth stages and the synthesis of plant hormones.
Chlorine
Involved in osmosis, the ionic balance necessary for photosynthesis and cell division.
Nickel
Required for iron absorption, enzymatic activity, and nitrogen metabolism.
Cobalt
Essential for nitrogen fixation in legumes and involved in various enzyme reactions.
Sodium
Beneficial for some plants, particularly C4 and CAM plants for osmoregulation and metabolic processes.
Silicon
Strengthens cell walls, enhancing plant strength and resistance to pests and diseases.
Selenium
Can play a role in anti-oxidant defense and may protect against environmental stress and predators.
Aluminum
Not essential and can be toxic at high levels, affecting root growth and nutrient uptake.
Cadmium
Non-essential and can be highly toxic, leading to reduced growth and impaired photosynthesis.
