At present, ferrous sulfate is generally used as a nutrient for plants to supplement iron in China. Its bioavailability is low, and the plant absorption rate is only 5-10%. If it is applied too much, it will also cause soil salinization, and the scope of application is very narrow. It can only be applied to acidic soil with pH ≤ 7, and it has no effect above pH 7. Due to the unique chelation reaction, EDDHA-Fe can be applied to the soil with pH ≤ 9 and can make plants absorb 100%, which greatly expands its application range. The dosage is only 1-5% of that of ordinary nutrients. After application, it has no negative impact on the soil. On the contrary, it can also fix the beneficial components in the soil, reduce the loss and adjust the acidity and alkalinity of the soil, prevent soil from hardening. EDDHA-Fe has unique super permeability and solubility in water, which is easily absorbed by plants, quickly provides crop nutrition, solves the symptoms of crop nutrient deficiency, increases crop yield, improves crop quality, enhances crop stress resistance and disease resistance, and promotes crop precocity.
EDDHA-Fe is suitable for iron deficient crops, as follows: fruit trees include sweet orange, lime, grapefruit, lemon, orange, peach, plum, cherry, apple, white pear, sand pear, loquat, persimmon, grape and apricot; Ornamental plants include mast flower, jasmine flower, Magnolia, camellia, hydrangea, Huangge orchid, Michelia, yellow rose, Rowan, Rhododendron, chrysanthemum, stick stem Begonia, hydrangea, white orchid, plum blossom and Tianzhu; The trees are Eucalyptus grandis, Eucalyptus tenuifolia, nanmu, Cinnamomum camphora, Robinia pseudoacacia and Kaimu; Legumes include peanut, soybean, broad bean and mung bean; Food crops include sweet potatoes.
Characteristics of EDDHA Fe
Ultra high efficacy: EDDHA Fe is the O-O isomer of eddha with the highest bioavailability. It is the top product of EDDHA chelated Fe. It has a very high bioavailability. Its efficacy is dozens of times that of ordinary organic iron EDTA and hundreds of times that of inorganic iron. It is recognized as the most effective professional product for the treatment of plant iron deficiency symptoms and yellow leaf disease in the world.
Super stability and solubility: it has excellent stability in the range of pH 3-9 in the soil, and is currently internationally recognized as the most stable chelated iron.
Good compatibility: it can be used with various pesticides, herbicides and other products, which greatly saves farming hours, is convenient to use, and can be stored for a long time.
High safety, good sustained release and long duration. Eddha chelated Fe fertilizer has the characteristics of non-toxic, harmless, no side effects, less application, greening and high yield increasing efficiency.
