GROWMAX-Zn is a high-efficiency chelated zinc fertilizer formulated with advanced EDTA chelation technology, which protects zinc from soil fixation and ensures efficient absorption and utilization by crops. The product effectively prevents and corrects physiological disorders caused by zinc deficiency, such as little leaf disease, leaf deformity, and stunted seedlings, guaranteeing healthy crop growth. GROWMAX-Zn maintains high stability in soils with pH 4–9, offering excellent mobility. Absorption and utilization rates are significantly higher than inorganic zinc salts, approximately 3–5 times that of zinc sulfate, reducing overall fertilizer usage. It is fully compatible with most chemical fertilizers and pesticides, including phosphate fertilizers, without causing antagonism or precipitation, making it safe and convenient for integrated crop management.
