High-Chelate Copper + Neutral Universal Adaptation: Enzyme-Active & Disease-Resistant Quick-Acting Copper Fertilizer

EDTA chelated copper (Cu 14.7%, core advantage) features a chelation rate of ≥98%, neutral pH 6.54, and 200-mesh blue powder. Relying on a stable chelate structure, it achieves deep synergy of "high-capacity copper retention + stable neutral efficacy + enzyme-activated disease resistance", avoiding the disadvantage of ordinary copper fertilizers being easily fixed by soil colloids. It integrates multiple functions: fast copper supplementation, nutrient deficiency correction, enzyme activity activation, and enhanced disease resistance. Suitable for various crops, especially copper-sensitive ones, it is the preferred product for efficient copper supplementation, quality improvement and disease prevention.

1. Mutual Enhancement: Chelate Activity Combined with High Content Using high-quality chelation technology to form a stable EDTA-copper complex, ensuring EDTA chelated copper content reaches 14.7% and chelation rate ≥98%. Copper exists stably in an easily absorbable form and can be directly absorbed by crop roots without additional conversion. The 200-mesh blue powder has fine particles and excellent dispersibility, dispersing quickly in water or soil without caking. Combined with the high chelation rate, it effectively prevents copper fixation, maximizes biological activity, adapts to different application methods, and realizes dual enhancement of "high-capacity activity retention + efficient absorption" to meet crops’ demand for concentrated copper supplementation.

2. Neutral Adaptation: Full Soil Compatibility The product has a stable pH of 6.54 (neutral), suitable for growth environments in neutral to weakly alkaline soils (pH 5.5–8.0). It precisely matches the physicochemical properties of such soils, solving the industrial pain point that copper is easily fixed by colloids and has low utilization rate, avoiding copper precipitation with soil colloids and ensuring long-term copper activity. The 200-mesh powder can evenly penetrate all soil layers, stably supplying copper in neutral fields, orchards or weakly alkaline substrates in greenhouses, optimizing soil copper availability and adapting to diverse planting soil scenarios.

3. Fast Copper Supplementation: Deficiency Correction & Physiological Enhancement The 14.7% high-content EDTA copper is rapidly absorbed through roots and leaves, accurately supplementing the copper needed by crops. As the active center of various enzymes in plants, copper activates redox-related enzymes, promotes nutrient metabolism and redox reactions, and enhances crop disease resistance. It quickly corrects copper deficiency symptoms such as young leaf yellowing, shoot dieback, poor fruit setting, and reduced disease resistance, improves weak crop growth, strengthens stress resistance, and lays a foundation for high yield and quality.

4. High Compatibility: Easy Formulation & Universal Adaptation The product has excellent compatibility, can be mixed with most water-soluble fertilizers and pesticides without antagonism or precipitation, no separate preparation required, and synergistically amplifies overall fertilizer and pesticide efficacy, meeting the convenience needs of large-scale planting. The neutral pH 6.54 fits most planting processes without extra pH adjustment, suitable for foliar spray, drip irrigation and fertigation. It covers both large-scale field planting and intensive planting of fruits, vegetables, grain and oil crops, satisfying copper supplementation needs of different crops.

5. Quality & Efficiency Improvement: Broad Adaptation & Cost Optimization Suitable for various copper-demanding crops including fruits, vegetables, grain and oil crops and cash crops, especially copper-sensitive crops such as wheat, rice, lettuce and citrus. It prevents copper deficiency, enhances disease resistance, promotes fruit setting, improves fruit quality and increases yield. The 200-mesh blue powder is easy to accurately weigh, store and transport, not easy to cake. With 14.7% high content, it achieves "low dosage, high effect", reduces copper waste, significantly improves fertilizer use efficiency, balances copper supplementation effect and planting cost control, meeting the needs of green agricultural development.

Expert Advice: Especially suitable for neutral to weakly alkaline soils and copper deficiency scenarios of various crops, especially copper-sensitive crops such as wheat, rice and citrus. It can be applied alone or mixed with conventional fertilizers via foliar spray, drip irrigation or fertigation. The 200-mesh powder dissolves completely without clogging pipes; spraying works better at seedling and reproductive growth stages. Adjust dosage according to crop copper deficiency level, avoid over-application, and control concentration for copper-sensitive crops to achieve precise copper supplementation, quality improvement and income increase.
