Chemical composition: Iron (Fe): 11% Description: DTPA (diethylene triamine pentaacetic acid complex) forms a stronger complex with iron tha the similar EDTA. The Fe-DTPA complex is stable in a PH range of 4-7. More and more, Fe DTPA is seen as the standard source of iron in fertigation. Advantage: 1. DTPA Fe 11% is a premium grade DTPA chelated iron fertiliser; 2. More stable than EDTA Fe at higher pH's; 3. Low sodium content - ideal for recirculating systems; 4. Supplied as free - flowing, dustless readily soluble microgranules; 5. Can be used in fertigation, as a foliar fertilizer or as nutrient in NPKS. 6. Compatible with soluble phosphated thereby remaining effective in hydroponics and liquid feed systems. Uses: An iron micronutrient source for hydroponics, liquid feed solutions and soilless growing media. Composition: Spray agglomerated microgranule formulation of ferric sodium diethylenetriamine penta acetate ( Fe DTPA) containing: Water soluble Fe: 11.0% Fe chelated by DTPA: min 10.5% Practical pH stability range: 4-7.5 (in aqueous solution).
