1.Plant nutritional supplements: Iron is one of the trace elements necessary for plant growth and development. A lack of available iron in the soil can cause iron deficiency symptoms in plants, such as yellowing of leaves. EDTA iron can be used as a nutritional supplement for plants, through soil application or foliar spraying, it can effectively provide the iron elements needed by plants and promote the normal growth and development of plants.
2.Foliar spray fertilizer: Can dissolve EDTA iron in water and provide iron element by foliar spray. This method can quickly and effectively supplement the iron elements that plants need, and is especially suitable for repairing symptoms such as leaf yellowing or poor vein greening by iron deficiency.

3.As a metal ion chelating agent: EDTA iron can combine with some metal ions to form a chelate, which has the functions of chelating, dissolving and stabilizing metal ions. In soil, EDTA iron can chelate iron ions, increase the stability and solubility of iron in soil, and improve the utilization rate of iron.
4.Plant disease control: Iron plays an important role in plant disease resistance and immune system. Iron EDTA can enhance the disease resistance of plants, improve the resistance and immunity of plants to pathogens, thereby reducing the occurrence and spread of diseases.

NOTE: It should be emphasized that when using EDTA iron, the correct dosage and method should be followed, the application should be carried out according to the specific crop and soil conditions, and the relevant regulations and recommendations on agricultural product safety and environmental protection should be followed.
