ADOB® CuK2 EDTA – 7%


ADOB® CuK2 EDTA – 7% is a specialty fertiliser, specifically designed to supply highly available copper cations to plants in moderate pH conditions. Owing to a patented production process, ADOB® CuK2 EDTA – 7% is characterised by several unique properties. The entire concentration of copper in the product (7.0% w/w) is 100% chelated by EDTA, making it completely effective and fully available to plants. ADOB® CuK2 EDTA – 7% is formulated as a stable, ready-to-use and high-purity aqueous solution, which makes it very convenient for growers to produce working solutions with. Since the production process does not include any sulphates, chlorides or nitrates, the material is anion-free.

The additional advantage of ADOB® CuK2 EDTA – 7% is that the product is also sodium-free, which is especially important in greenhouses and areas with higher salinity. Consequently, there is no risk of sodium build-up, while at the same time the potassium contained in the product (K2O at 10.4% w/w) is fully plant-available. This product serves as an effective source of copper and is mainly recommended for foliar application, hydroponics and fertigation. It is recommended for preventive and corrective fertilisation in all agricultural and horticultural crops.

Copper functions as a highly active element in redox reactions, participating in photosynthesis, respiration, carbon and nitrogen metabolism, and in protection against oxidative stress. It is a crucial factor in the appropriate lignification process of cell walls, especially the xylem vessels, as well as in pollen formation and seed-set. ADOB® CuK2 EDTA – 7% enables the quick correction of copper deficiency, and eliminates the physiological disorders it causes (such as reduced redox activities, distortion of young leaves, bending and twisting of stems and twigs, impaired flower and fruit formation, pollen sterility and reduced seed-set).
