Due to the unique chelation reaction, this product can be applied to soils with pH ≤9 or less, which can make plants absorb 100%, so that the application range is greatly expanded, and the dosage is only 1-5% of common nutrient. After that, it has no negative impact on the soil. On the contrary, it can fix the beneficial components in the soil, reduce the loss, and help regulate the acidity and alkalinity of the soil and prevent the soil from hardening.

Application |
EDDHA Fe6 is highly active chelated iron elements. It is a dark brown or black powder. It is water soluble, which can be quickly absorbed. And is the most effective product to cure the plants of chorosis of iron. It can be applied in any soil with pH value 4.5-9.0. The crop absorption rate of EDDHA Fe6 is pretty higher than traditional iron chelated fertilizers like EDTA-Fe, FeSO4, especially in alkaline soil. . |

Product Character
Ultra-high efficacy: EDDHA iron is the most bioavailable EDDHA OO isomer molecule. It is the top product of EDDHA chelated iron. It has a very high bioavailability and is recognized worldwide as a symptom of iron deficiency in plants. Leaf disease is the most effective professional product.
Super stability and solubility: It has excellent stability in the range of pH 3-9 in the soil and is the most stable chelated iron which is currently recognized internationally.
Good compatibility: It can be used together with various insecticides, herbicides, etc., which greatly saves agricultural time, is convenient to use, and can be stored for a long time.
High safety: Good sustained release and long duration. It has been experimentally demonstrated that EDDHA chelated iron fertilizer has the characteristics of non-toxic and harmless, no side effects, less application, complex greening and high yielding efficiency.
Usage and dosage
1) Root irrigation method: Dissolve EDDHA iron in a small amount of water first, and then add appropriate amount of water as needed for later use. Pour the soil evenly around the crown of the fruit tree or along the sides of the plant. The soil with poor permeability needs to dig a 15-20 cm deep trench. Pour the solution evenly into the trench and fill it up immediately. Finally, add water equal to the solution It can be evenly distributed in the ditch and penetrate into the roots.
2) Drip irrigation and flushing application method: Regularly add to irrigation water, flush with the water, the number of applications depends on the severity of iron deficiency, increase or decrease in an appropriate amount, and the dosage is 70-100 grams per mu.
3) Foliar spraying: Dilute 1000-3000 times with water and apply. Foliar spraying is not recommended in the case of strong sunlight and low rainfall.
4) Expert advice: Fruit trees: Apply twice in a fruiting cycle, once for new leaf budding, and twice for flower fall. The amount of one application per plant is 30 grams, and the amount of top dressing for the second time is halved; according to the ratio of 1 gram of this product to 0.5 liters of water, it is then applied to the root soil to make the roots evenly fertilized.
Leguminous plants: Apply twice in a fruiting cycle, once for the budding stage of new leaves, and twice for flower fall; once the application amount is 250g-500g per acre, and the amount of topdressing for the second time is halved, and 1 g of this product is used The proportion of 0.5 liters of water, after dissolving this product with clean water, spray on the leaves.
Ornamental plants: Refer to the usage and dosage of leguminous plants, and apply once when the new leaves are sprouting. Other crops can be used according to the above method
1) Spraying time should avoid high temperature and sunlight, and do not spray other iron fertilizers after spraying.
2) EDDHA iron has super solubility, and it is easy to absorb moisture in the air and cause agglomeration, but it will not have any impact on its quality. The unused part should be sealed and stored.
3) The appearance and color of EDDHA iron are different due to the difference in pH value and fineness, but it does not affect the internal quality of the product.
