EDDHA-FE

EDDHA-FE Currently the world's most efficient iron fertilizer. Within the scope of PH 3-12 is high stability, plants are more likely to be absorbed. Chemical name: Ethylenediamine two adjacent hydroxyphenyl big iron sodium acetate;EDDHA - FeNa Molecular formula: C18H16N2O6FeNa molecular weight: 435.2 Quality indicators: Outside view: purple or brown solid powder, soluble in water, water solution PH value (1% solution) 7.0 ~ 9.0, it is mainly used for iron preparation plants. Including: chelate iron content: 99% or higher in (C18H16N2O6FeNa) Iron content: 6.0% or higher, pH value of aqueous solution (1%) : 7.0 ~ 9.0 Plant iron deficiency symptoms: Young foliage become yellow or white, central veins, leaf margin, and tip necrosis blotches burned;Flowers younger leaves lose green, old leaves still looks normal, losing green leaves start mesophyll turning yellow, then leaves turned white, the veins become yellow and leaves fall off. use crops and method : Soil base: irrigating root Fruit, peach, orange, pear, apple, navel orange, kiwi fruit, litchi, loquat, dongzao, cherry, etc The young tree 4 to 12 g/tree Hanging in the early fruit 12 to 20 grams/tree Adult tree 20-40 grams/tree Old tree 40-80 grams/tree seedbed: Plant 0.8 to 4.0 grams Every square metre 2.4 to 4.0 grams Stolons plants: grapes, strawberries, etc young plant 2.4 4.0 g/strain Adult plant 4 to 8 g/plant Flower gardening: lily, rose, African chrysanthemum, carnation, anthurium, sowbread, chrysanthemum, yulan, etc Every square metre 0.8 4 grams Used with nutrient solution drip irrigation, a 40% reduction in usage
