Gran PROD UCT I N FO R MATI O N TR AC E E L E M E NTS Oligo Iron-HBED 9% HBED, short for N, n’-Bis- (2-Hydroxybenzyl) ethylenediamine-N, n’Dipropionic Acid, is a chelate that protects iron against precipitation up to a very high pH of 12. The stability constant of Fe-HBED is even higher than that of the Fe-EDDHA chelate with the highest orthoortho percentage. In contrary to the EDDHA chelate, the HBED chelate has no isomers. Therefore the stability constant is always high and doesn’t depend on the ortho-ortho percentage, which is difficult to analyse. Mainly used for nourishing plants in fertigation systems In contrary to the EDDHA chelate, HBED has a limited affi nity to copper. This means that the risk of copper accumulation is far smaller. All this makes the HBED chelate the most effective chelating agent on the market. Van Iperen International offers a micro-granulated product which is easily water-soluble. If you are looking for the very best product to cure iron defi ciency, Fe HBED is your choice.
