Calamag is a unique water-soluble granular compound fertiliser containing calcium nitrate and magnesium nitrate. Calamag contains the ideal calcium/magnesium ratio to prevent competition between these two.

Calcium and magnesium are both secondary plant nutrients, essential for plant growth. Calcium plays a vital role in cell wall formation, root development, and overall plant structure. Magnesium is an essential component of chlorophyll, the pigment responsible for photosynthesis. Using a calcium-magnesium nitrate fertilizer ensures an adequate supply of these nutrients, promoting healthy plant growth. In addition, calcium and magnesium replace sodium bound in the clay particles in the soil,

Nitrogen is present in the form of nitrates, which makes it readily available for plants. Nitrogen is essential for leaf and stem growth, as well as protein synthesis. It enhances the overall vigor and green color of plants.

Overall, using Calamag provides a comprehensive nutrient package that improves leaf colour, fruit quality and shelf-life.
