EDTA-Cu (EDTA chelated copper) is a high-purity water-soluble copper micronutrient produced via advanced EDTA chelation technology. Unlike ordinary inorganic copper fertilizers such as copper sulfate, the EDTA molecule tightly encapsulates copper ions to form a stable organic structure. It isolates interference from soil pH, phosphate and carbonate, keeping copper ions soluble, active and plant-available without fixation or precipitation.

Copper is an essential micronutrient for crops. It plays a vital role in chlorophyll formation, photosynthesis, respiration, protein synthesis and nitrogen fixation. As a core component of multiple oxidase enzymes, copper stabilizes plant physiology, strengthens cell wall toughness and supports stable yield and quality improvement.

Traditional inorganic copper easily deactivates in alkaline soil and tends to cause leaf burn and root damage due to unstable concentration. In contrast, EDTA-Cu features wide pH adaptability, mild properties and high safety. Fully water-soluble and residue-free, it is suitable for foliar spraying, drip irrigation and fertigation, serving as the premium choice for standardized copper supplementation in modern agriculture.
