After Nitrogen, Phosphorus and Potash, Calcium is the 4th most important nutrient for a plant.

Calcium in the medium brings a lot of nutrients under the reach of the plants by displacing ions. In addition, the Calcium promotes the decomposition of organic substances, which also makes many nutrient elements available.

The yields of a crop will therefore increase sharply after the addition of Calcium, but the soil medium only seems to be more fertile. In reality, the medium becomes impoverished because the plant absorbs more nutrients.
By simply fertilizing more fertilizers, we eliminate this problem, resulting in an even higher yield from the harvest.

Calcium is indispensable in the plant. It binds acids that would poison the plant body, including the oxalic acid and Calcium, together with protein (Nitrate), in a certain compound in the cell wall.
If the plants do not contain enough Calcium, they form long, weak stems. The leaves are therefore limp and the root system develops moderately.



However, for the build-up of Calcium and Protein in the plant cells, Boron is needed that bricklays these elements into the cell walls like a bricklayer.
However, the pH of the medium must then be 6.2 or lower because otherwise Boron will not be absorbed or will be absorbed less.

Because Calcium Nitrate strengthens the plant cells with the help of Boron (becomes vitamin B12), this results in a stronger plant with less chance of fungus and rot formation and a heavier final yield.
