Calcium is the fourth most important nutrient for a plant, after nitrogen, phosphorus, and potassium.
Calcium in the medium makes many nutrients available to plants by displacing ions. In addition, calcium promotes the decomposition of organic matter, which also provides many nutrients.
Yields of a crop therefore increase significantly after calcium is added, but the soil medium only appears more fertile. In reality, the medium becomes depleted because the plant absorbs more nutrients.
By simply fertilizing with more nutrients, we solve this problem, which results in an even higher yield from the crop.
Calcium in the root zone also binds oxalic acid waste from the plant, which would otherwise acidify the soil.
Calcium is also indispensable inside the plant. Calcium, together with protein (nitrate), is an important component of the cell wall. We call such a calcium nitrate building block the "cement for the cells."
If plants do not contain enough calcium, they develop long, weak stems. Leaves become limp, and the root system develops poorly.
The best option for plants is a liquid calcium nitrate fertilizer for easy uptake.
Boron
For a strong and stable build-up of calcium and protein in plant cells, boron is required. Boron works like a mason, placing these elements into the cell walls. Boron is converted into Vitamin B12 to perform this function.
It is important that the pH in the medium is 6.2 or lower, because at higher pH levels, boron is absorbed less or not at all.
When calcium nitrate fertilizer strengthens the plant cells with the help of boron, it leads to stronger plants with less risk of fungal and rot development and more weight in the final yield.
