*Uses:- 1- An effective compound for treating the symptoms of iron deficiency in various crops. 2- It is considered the most important factor in the formation of chlorophyll within the plant, which works to increase the efficiency of photosynthesis. 3- It is involved in the synthesis of oxidation and reduction enzymes that are important for the respiratory process. 4- It works on plant activity as it contains a chelating substance. 5- It increases the plant’s ability to tolerate cold and also works to early production. 6- It is involved in the process of protein catabolism and synthesis, energy exchange processes, and nitrogen fixation. 7- Iron helps in the formation of plant pigments such as carotenoids and xanthophylls. 8- It increases the plant’s ability to resist diseases and stress due to its involvement in the formation of many oxidation enzymes, the most important of which is peroxidase. *Spraying equipment:- - Dosage: At a rate of 100 g/acre in the normal state of the elements in the soil and plants. - Dilution: at a rate of 100 grams / 300 liters of water per acre (depending on nutritional status and lack of elements).
