Since ages, phosphor has been known for its role as activator of root activitity and blooming of plants. Phosphor also plays a role in the forming of celmembranes 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 discolorisation 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 BN 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. BN P 20 % is absorbed fast, and does not have any side-effects. BN 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 25-100 ml. per 100 liters of nutrient solution as an addition to other fertilizers. Beware: a too high a dosage might influence the absorption of other nutrients.
