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.
P 20 is absorbed fast, and does not have any side-effects.
P 20 is free of chlorides or other excess ingredients.
A dosage of 1:1000 increases the total amount of P by 3.5 mmol.
In order to stimulate root development and/or flowering add 1-5 ml. per 10 litres of nutrient solution as an addition to other fertilizers. Beware: a too high a dosage might influence the absorption of other nutrients.
