This product contains 15% (180 g/l) pure calcium and 3% nitrogen and the trace elements iron, copper and manganese. Calcium is abundant in cell walls and membranes and plays a special role in ion reactions in the plant. Calcium is transported in the plant via the evaporative flow (xylem). In situations with high humidity or in a dense crop, this evaporative flow is small and therefore a deficiency may occur.

Calcium deficiency weakens cell walls and this immediately manifests itself in higher fungal susceptibility and growth tips and young leaves die.
An excess of calcium can sometimes occur and cause brown spots on the leaves.

Ca 15 is a very pure product that works quickly and does not raise the pH.
Ca 15 is economical to use and contains 180 grams of pure lime per litre of liquid.
Ca 15 can be used in any growing medium, does not clog or pollute.

A dosage of 1:1000 increases the Ca figure by 3.2 mmol.
