This product contains 20% P2O5. Phosphorus has long been known for its role as a root and flowering activator in plants. Phosphorus also plays an important role in cell membranes and as a building block for DNA and energy transport molecules such as ATP and ADP.

Phosphorus is also involved in proper sugar metabolism and the formation of enzymes. Phosphorus deficiency is manifested by decreased growth and discolouration of the veins and underside of leaves and purple colouring of stems due to the accumulation of anthocyanins.
