Van Iperen Optifos Liquid is a pure and highly concentrated Phosphate product where Phosphate is available as a mixture of different polyphosphates (chains of ortho-phosphates). Our product is a transparent, stable solution and is recommended throughout the growing season. Especially during periods of intensive growth and when the pH in the irrigation system tends to increase. The high level of specific Polyphosphates in our formula increases plant available Phosphate and prevents anorganic pollution of the dripping systems and therewith clogged drippers.
