EDDHA, is a chelate that protects nutrients against precipitation in a wide pH-range: 4-9, which is higher than EDTA and DTPA in pH range. This makes the EDDHA-chelates suitable for alkaline and calcareous soils as well as soils containing high levels of carbonate. It is mainly used for fertigation in open fields and soil injection as well as fertigation in high tech, soil-less cultures. The product contains the highest percentage of the ortho-ortho isomere: 4.8% o-o and it is easy, rapid to dissolve in water and compatible with most water-soluble fertilizers.
