Both granular and liquid fertilizers are corrosive to some degree. Liquid fertilizers are corrosive on steel, brass, copper, zinc, some aluminium (and their alloys) and concrete. If not carefully managed, corrosion can become an expensive problem, contaminating fertilizers and causing mechanical damage to plant machinery.
To prevent corrosion after contact with liquid fertilizers, we recommend using equipment made from polythene, PVC, ceramic or stainless steel. Some grades of aluminium are also suitable. At the end of each spraying period, all equipment that has come into contact with liquid fertilizer should be washed thoroughly with water.
Note: Use of trace elements in the spray will increase the corrosion risk.
All formulations should be used with 20% water.
