Features:
1. Super high efficacy: EDDHA Fe is the EDDHA 0-0 isomer molecule with the highest bioavailability. It is the top product of EDDHA chelated iron. It has extremely high bioavailability and is dozens of times more effective than the general organic iron EDTA. , hundreds of times more than inorganic iron, it is currently recognized as the most effective professional product in the world for treating plant iron deficiency symptoms and yellow leaf disease.
2. Super stability and solubility: It has excellent stability in the soil pH range of 3-9 and is currently the most stable chelated iron recognized internationally.
3. Good compatibility: It can be used with various pesticides, herbicides and other products, which greatly saves agricultural time, is convenient to use, and can be stored for a long time.
4. High safety, good sustained release and long lasting effect. Experimental verification shows that EDDHA chelated iron fertilizer is non-toxic, harmless and has no side effects.
How to use and dosage:
1. How to use for root irrigation: Dissolve the EDDHA iron with a small amount of water first, then add an appropriate amount of water as needed and set aside. Dig a 15-20 cm deep trench around the crown of the fruit tree or along both sides of the plant. Pour the solution evenly into the trench and fill it immediately. Add the amount of water so that the solution can be evenly distributed in the trench and penetrate into the roots.
2. Drip irrigation and flushing application methods: Add to irrigation water regularly and flush with the water. The frequency of application should be increased or decreased according to the severity of iron deficiency. The dosage per mu is 70-100 grams.
3 Foliar spraying: dilute 3000-5000 times with water and apply.
4. As a raw material for foliar fertilizer, flush fertilizer and compound fertilizer: EDDHA chelated iron can be well absorbed in the soil with a pH value of 3-12. (The higher the pH value, the better the EDDHA chelated iron is compared to EDTA chelated iron and EDTA chelated iron. The more obvious the advantages of ferrous sulfate are), the application effect of this product will be best when the crops are not short of water and basic fertilizer. Since the lack of one kind of fertilizer will also cause the lack of other trace fertilizers, the deficient fertilizer should be determined before application, and it can be applied in conjunction with other chelated trace fertilizers such as zinc, manganese, magnesium, etc. EDDHA chelated iron can be stored at room temperature for a long time, but for the convenience of users, it is recommended to store it in a dry place and seal the packaging tightly if it is not used up once.
5. Expert advice: Fruit trees: Apply twice in a fruiting cycle, the first time during the budding period of new leaves, and the second time when the flowers fall. The first application amount per plant is 30 grams, and the second application amount is halved; use the ratio of 1 gram of this product to 0.5 liters of water, and then apply it to the root soil to make the roots evenly fertilized.
Leguminous plants: Apply twice in a fruiting cycle, the first time is during the budding period of new leaves, and the second time is when the flowers fall; the first application amount is 250g-500g per acre, and the second time the amount of top dressing is reduced Half, according to the ratio of 1 gram of this product to 0.5 liters of water, use clean water to completely dissolve this product before spraying it on the leaves.Ornamental plants: Refer to the usage and dosage of leguminous plants, and apply once during the budding period of new leaves.
Other crops should be used according to the above usage methods. Generally speaking, the larger the dosage, the better the effect, but not too much.
