A microcrystalline formulation of iron ethylenediamin etetraacetate (Fe EDTA) containing 13.2% water soluble Fe.
Used as an iron micronutrient source for hydroponics, liquid feed solutions and inert substrates. Also to prevent and correct iron deficiency in most, horticultural, ornamental and arable crops.
Recommended for foliar application.
For use with a Knapsack sprayer prepare a 0.05-0.1% (0.5-1.0 gram per litre) solution and apply so as to coat the leaves and stems with a thin film of moisture with little or no run-off.
For hydroponic use a 1ppm (17.86 µmol/L) iron can be achieved by adding 7.5 grams per 1000lt of solution.
