CalMag 3-4M

10-0-0+17CaO+5MgO

Fully coated calcium and magnesium fertilizer. Controlled release nitrogen, calcium and magnesium in one product. For pot plants, bedding plants, perennials and container nursery stock crops, providing extra calcium and magnesium. Ideal for mixing in substrates and beneficial in peat reduced growing media (substrates with woodfibre, bark, cocopeat, compost). Very suitable to use in combination with other Osmocotes and water soluble fertilizers.
  • Apply controlled release nitrogen, calcium and magnesium with one product
  • The solution for soft water irrigation systems: give your crops the calcium and magnesium they need
  • Efficient calcium nutrition, thanks to daily release; in line with the plant’s calcium need
  • Apply this product with other Osmocote products to make strong combinations
  • Osmocote CalMag adds extra nitrogen during the first months of the growing cycle, when this is required by the crop (for example in perennials)
  • Easy to use, effective calcium fertilizer with patterned release
  • Lower emissions of nutrients, compared to water soluble calcium nitrate.

It is recommended to use Osmocote CalMag in combination with other Osmocote products or water-soluble fertilizers.

The recommended application method is mixing into the substrate to obtain good granule distribution.

The product is ideal for use in specific situations where extra calcium or magnesium is needed. For example:

  • Soft water conditions, where Osmocote CalMag can be used as base application of calcium and magnesium
  • Peat-reduced potting soils, where Osmocote CalMag can compensate the nitrogen consumption of the materials and lack of calcium due to no or less liming.
  • Crops with a high nutrition need for calcium or magnesium.
