İGSAŞ COMBI; Water-soluble 4% iron (Fe), fully chelated with EDTA; 4% water-soluble zinc (Zn), fully chelated with EDTA; 3% water-soluble manganese (Mn), fully chelated with EDTA; 0.5% water-soluble copper (Cu), fully chelated with EDTA; It contains 0.1% water-soluble boron (B) and 0.1% water-soluble molybdenum (Mo). Since it dissolves easily and quickly in water, it can be applied to the soil with irrigation and to the leaves with a sprayer. Its usefulness is always high because it contains almost all of the micronutrient elements, deficiencies of which are frequently seen in our agricultural soils, in appropriate proportions and metallic cation nutritional elements in chelated form. The pH range in which zinc, manganese and copper EDTA chelate is stable is 4-11, while the pH range in which iron EDTA chelate is stable is 4-7.
