**Addition in g/l in growing systems** *We recommended you adjust the rate of Osmocote® Exact when Osmocote® CalMag is mixed in. Important: maximum dosage starter fertiliser is 0.5 kg/m3 growing medium. Maximum rates are based on pot volumes. These recommendations supersede all previous instructions. Plant hole dibbling and side dibbling are not recommended. In case of pre-mixing in growing medium bunker, please consult your ICL advisor. Attention Store the product in a cool, dry and ventilated place. Trial first on a small scale before changing the rate, application or any other variables.

It’s best to mix it into the substrate, for good granule distribution.

Osmocote® CalMag is ideal in specific situations where extra calcium or magnesium is needed, for example:
4
Soft water conditions, where it can be used as a base application of calcium and magnesium
5
Peat-reduced potting soils, where it can compensate the nitrogen consumption of the materials and lack of calcium due to no or less liming
6
Crops with a high nutrition need for calcium or magnesium
