P 20

This product contains 20% P₂O₅. Since ages, phosphor has been known for its role as activator of root activity and blooming of plants. Phosphor also plays a role in the forming of cel membranes and it is a molecular building block for DNA and the energy carriers ATP and ADP. Furthermore, phosphor also establishes a good metabolism of sugars and makes for the forming of enzymes.

A deficiency of phosphor manifests itself in a slow growth and purple decolourisation of the nerves at the lower surface of the leaf and purple stems caused by an anthocyan-accumulation. An excess of phosphor results in an ill-growing plant with an induced shortage of zinc.
Before P 20, it used to be a problem to add any form of phosphor to crops that would be absorbed entirely and very fast without any harmful side-effects.
