7. FAQ

Q1: What is the difference between EDTA Chelated Copper and ordinary inorganic copper fertilizer?

A1: Ordinary inorganic copper is easily fixed and invalidated by soil ions, with low plant absorption rate and easy phytotoxicity. Our Copper EDTA adopts full chelation structure, which is stable in soil and nutrient solution, will not produce precipitation. It has 10 times higher utilization rate than inorganic copper, with safer performance and more lasting efficacy, suitable for high-standard agricultural planting and fertilizer processing.

Q2: What are the main physiological functions of Copper EDTA for plants?

A2: Copper is an essential micronutrient for plant growth. EDTA chelated copper can activate plant enzyme activity, promote chlorophyll synthesis and photosynthetic respiration, strengthen cell wall lignification, enhance crop disease resistance and lodging resistance. It also effectively improves copper deficiency symptoms such as leaf tip withering, leaf chlorosis, stunted growth and poor flowering and fruiting.

Q3: Can Copper EDTA be mixed with other fertilizers and pesticides?

A3: Yes. It has excellent compatibility and can be safely mixed with neutral and acidic water-soluble fertilizers, amino acid fertilizers, humic acid fertilizers and most pesticides. It is not recommended to mix with strong alkaline products to avoid molecular structure damage and reduced efficacy.

Q4: Is Copper EDTA suitable for hydroponic and soilless culture?

A4: Absolutely. Copper EDTA maintains stable activity in water body, will not precipitate with nutrient ions, and can provide long-term available copper elements for hydroponic crops. It solves the problem of insufficient copper supply and growth decline in soilless culture, and is a special trace element additive for greenhouse hydroponic systems.

Q5: Will long-term use cause soil and crop damage?

A5: No. Our high-purity Copper EDTA has ultra-low impurity content, no harmful residues, and will not cause soil hardening, heavy metal accumulation or crop phytotoxicity. The chelated copper is easily absorbed and metabolized by plants, suitable for long-term continuous use in organic and green planting systems.

Q6: Can it be used as a professional fertilizer additive for compound fertilizer production?

A6: Yes. This product is specially designed for fertilizer compounding, with stable physical and chemical properties, good fluidity and high compatibility. It will not react with other nutrient elements, can effectively improve the trace element activity of finished fertilizers, and enhance the comprehensive efficacy of commercial water-soluble fertilizers.
