Product Introduction
Product Overview
EDTA Copper Dipotassium (EDTA-CuK₂, also known as dipotassium EDTA copper, EDTA dipotassium copper) is a highly effective EDTA chelated copper fertilizer. Product is blue powder, chelated copper content ≥12.5%, pH (1% solution) 6.0-7.0, water insoluble ≤0.1%.
Core Advantages
- High Copper ContentChelated Copper ≥12.5%, meets crops' demand for trace element copper
- High StabilityEDTA chelated copper, stable in soil and solution
- Fully Water-SolubleBlue powder, fully water-soluble, dissolves quickly, suitable for all irrigation systems
- High Absorption RateCopper exists in chelated form, can be directly absorbed and utilized by crops
- Low impuritiesWater insoluble ≤0.1%, high purity
Application Reference
Recommended Dosage
| Application Method | Recommended Dosage | Precautions |
|---|---|---|
| Foliar Application | 0.5-1.0 kg/ha | Dilute 1000-2000 times, spray evenly on both sides of leaves |
| Drip Irrigation / Foliar Application | 1-2 kg/ha | Apply with irrigation water, avoid mixing with strongly alkaline fertilizers. |
| Water-Soluble Fertilizer Blending | 1-3% | Conduct a pre-dissolution test when used with other micronutrients. |
Usage Recommendations
- Apply on cloudy days or in the evening, avoiding strong light and high temperature periods.
- Can be mixed with most pesticides and foliar fertilizers; a small pre-test is recommended before mixing.
- When dissolving, first add the product to clean water, stir until fully dissolved, then add other fertilizers.
- Adjust application frequency based on crop copper deficiency level and growth stage, typically every 15-20 days.

FAQ
EDTA-CuK₂ is an EDTA chelated copper fertilizer, and its main differences from ordinary copper fertilizers are:
- StabilityEDTA chelated copper is stable in soil and solution, not prone to precipitation
- Absorption rateThe chelated copper can be directly absorbed by crops, with an absorption rate much higher than ordinary inorganic copper fertilizers.
- Water SolubilityFully water-soluble, no sediment, suitable for various irrigation systems
