Calcium Chelate

Calcium Chelate

Calcium Chelate is a premium, fast-acting source of plant-available calcium for foliar and root applications. Chelated with lignosulphonate, it improves calcium uptake, nutrient transport and overall plant structure.

Whether you’re replacing mineral calcium sources like calcium nitrate or seeking a sustainable alternative to synthetic chelates like EDTA, Calcium Chelate delivers unmatched performance.
