Chelating agents are widely used in chelated fertilizers in hydroponics, soilless culture, fertigation, foliage dressing, etc.
EDTA chelates, DTPA chelated iron, HEDP (Etidronic acid), ATMP are used for chelating metal nutritions for crop.
Chelating agents are widely used in water treatment chemicals, softeners, scale inhibitor, iron control, textiles aids, oilfield/oil drilling chemicals, etc.
Potassium polyaspartate, HPMA are used in reclamation of saline-alkali soil.
Potassium polyaspartate is used as fertiliser synergist too.
