Calcium Magnesium Nitrate


How to Buffer Cocopeat:

When soaking 5Kg Coco brick, use 20L water and 50g Cal Mag to buffer coco.

Soak the cocopeat in the solution for 12 hours. Drain any excess solution and rinse the cocopeat with pH balanced water.

Note: The buffering process involves pre-soaking with a Cal-mag, which displaces the sodium and balances the naturally occurring potassium. After the soaking period, the media is washed with water, which removes the displaced sodium, leaving the calcium in the coir. This buffering process prevents unwanted draw down or ‘lockout’ of calcium and magnesium, and avoids sodium toxicity issues.

Calcium Magnesium Nitrate

Calcium Magnesium Nitrate (Cal Mag) is a calcium magnesium nitrate fertilizer which is a best fertilizer to supply Calcium and Magnesium to plants.

  • Cal Mag is a high use efficiency and quick uptake by crops.
  • Cal Mag is high water solubility, quick dissolved in water and also suitable to be applied by irrigation.
  • Cal Mag is also used to buffer Coco peat.

When adding to plants – 1/4tsp per 3 Litres of water.
