EDDHA - Fe chelate iron of Chengdu auspicious clouds chemical co,.ltd  is the highest biological utilization EDDHA 0-0 with heterogeneous elements(4.8), is the top of the chelate iron products is currently the world governance and yellow leaves plant iron deficiency disease the most effective professional products!Has biological activity such as high efficiency, high quality, super (is the effect of ferrous sulfate hundreds, several dozen times the general organic iron effect) in soil PH range of 3-10 strong stability, this product has the full water-soluble, fast dissolving, absorb quickly, quick effect, safe, convenient and increase rate of big characteristics such as improve the quality of the products!
Iron deficiency branches (yellow leaf disease) is a cosmopolitan plant physiological disease, can reduce plant leaf Huang Zhi blight, products, quality to drop, serious when even death of trees.Traditionally use the iron preparation easy oxidation of ferrous sulfate precipitation is difficult to be absorbed by the plant, using, damage to the soil, is not conducive to green agriculture sustainable development.
Technical indicators:
Product name: EDDHA-FE chelate iron powder.
Chemical name: two adjacent hydroxyphenyl acetic acid sodium EDDHA iron - FeNa (CAS No: 16455-61-1)
Molecular formula: C18H16N2O6FeNa.
Molecular weight: 435.2.
Appearance: dark brown particles.
Chelate iron content: 99% or higher in (C18H16N2O6FeNa).
The iron content: 6.0% chlorine content or higher: 0.1% or less
Aqueous solution pH value (1%) : 7.0 ~ 9.0.C18H16N2O6FeNa is a stable water-soluble metal chelate, which exist in chelating state of iron.
Solubility in water: about 60 g / 1 (20 ℃).
Bulk density: 650 ~ 750 kg/m3.
Biodegradability: general.
Directions for use:
Within the scope of the soil PH 4.5-9 plants can be a good absorption.(the higher the PH, EDDHA chelating iron compared with EDTA chelation iron and ferrous sulfate, the more obvious advantage.)
When crops based on water and fertilizer, the application effect of the product will be the best.Due to the lack of a kind of fertilizer can also cause the lack of other microelement fertilizer, so before applying it to deal with lack of fertilizer for sure.
Can be compatible with other chelating micronutrient fertilizer and soluble phosphate.
EDDHA chelating iron can be long-term storage at room temperature conditions, but for the user easy to use, recommended store in dry place, one should be sealed tightly, the packaging.
1. Spraying on the leaf:
EDDHA chelating iron fertilizer used for spraying on the leaf effect very good, the concentration of 0.1%, 1 week spraying time, the general continuous spraying 2-3 times can achieve the ideal effect.(the number of spraying depends on the degree of iron deficiency)
2. The soil application:
1) to use the soil EDDHA-FE chelate iron - the best way is to match the right amount of water into the solution concentration (0.1%), and then to fill the root.Such as soil harden and need before filling root scarification.
2) the habit of using flood irrigation area to the north, can be combined with water will EDDHA iron with water amount, amount for each 1 kg/mu.
3) for fruit trees or shrubs, can be good solution with pressure syringe injection to the plant roots.
Introduction ][ characteristics
1, product iron directly to ferrous iron, do not need to plant roots into again, can be directly plant use, use a few days later can obviously alleviate symptoms of green plant iron deficiency;
2, the product is sustainable and stable directly by foliar absorption, and the available state persist in plant body, sustainable plant iron element;
3, within the scope of the soil PH 4.5-9 plants are good absorption (the higher the PH, EDDHA-fe chelate iron relative to the advantage of EDTA chelation iron and ferrous sulfate, the more obvious).
4, using the exclusive production technology, EDDHA - Fe to ensure high-quality, at the international leading position;
5, high safety, good slow release, the effective length.
