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 In the root zone also binds the plant Oxalic acid waste that would acidifies the soil.
Calcium is also indispensable inside the plant. Calcium, together with protein (Nitrate), is an important compound in the cell wall. We call such Calcium Nitrate building block the "cement for the cells".
If the plants do not contain enough Calcium, they form long, weak stems. The leaves are therefore limp and the root system develops moderately.
Best for plants is a liquid calcium nitrate fertilizer for an easy take up.
Boron
For a good and strong build-up of Calcium and Protein in the plant cells, Boron is needed that brick lays these elements into the cell walls like a bricklayer. Boron becomes vitamin B12 to fulfil this function.
Important is that the pH in the medium must than be 6.2 or lower because with a higher pH the Boron will not be absorbed or will be absorbed less.
When Calcium Nitrate fertilizer strengthens the plant cells with the help of Boron, this will result in a stronger plant with less chance of fungus and rot formation and more weight in the final yield.
