Description

Calcium often appears in the cell walls and membranes and plays a special role in the ion-reactions within plants. Calcium is transported in the plant by means of water conduction (xylem). In situations with a high humidity or in a compact crop the rate of conduction is small and can lead to a deficiency of calcium. A deficiency of calcium leads to softened cell walls which manifests itself immediately in an increased sensitivity to fungi and the dying off of young leaves and growing points. An excess of calcium can also occur. Which results in brown spots on the leaves.
