All nutrients are essential for optimal growth

Plants require nitrogen, phosphorus, potassium, calcium, magnesium and sulphur in greater quantities, hence they are called macronutrients. The ones called micronutrients – iron, boron, manganese, zinc, copper and molybdenum – are required in smaller quantities but are essential for plant growth.

Vital primary nutrients

Nitrogen is essential for plant growth and crop formation as it is a building block of many crucial compounds. Nitrogen promotes rapid growth and increases seed and fruit production.

Phosphorus is required in photosynthesis, energy transport and storage compounds as well as root formation. Phosphorus hastens maturity and seed production.

Potassium improves disease resistance, photosynthesis and the quality of seeds and fruit. High potassium content reduces the unwanted stretching of plants.

Essential secondary nutrients

Calcium is part of the signalling mechanisms that alert plants of environmental stress. It is also required for strong shoot and root formation.

Magnesium is essential for photosynthesis and protein synthesis. Many plant enzymes require magnesium as an activator and component.

Sulphur is a building block of many necessary compounds. It improves resistance to cold and helps with vigorous growth.

Important micronutrients

Iron is necessary in photosynthesis. Boron is essential for seed and fruit formation and helps in the use and regulation of other nutrients.

Manganese and molybdenum aid in nitrogen metabolism. Manganese is also part of the breakdown of carbohydrates.

Zinc aids in regulating plant growth and is part of carbohydrate metabolism.

Copper is required for reproductive growth and root metabolism.
