Impact Fertilisers
Fertiliser Made Easy


Phosphorus is present in every living cell, both plant and animal. It is required by all plants for growth. No other nutrient can be substituted for it. Phosphorus plays a role in all major metabolic processes in the plant including photosynthesis, respiration, energy storage and transfer, cell division and cell enlargement.

Phosphorus is critical for early root development and hence must be applied prior to or at planting for annual crops. Importantly it must be applied in the region where the seed will germinate as Phosphorus does not readily move in the soil. The root system must come into contact with Phosphorous for adsorption to occur.
