-
In soil, calcium replaces hydrogen (H) ions from the surface of soil to reduce acidity
-
Calcium facilitates the movement of N-P-K and other nutrients into the plant system.
-
For this reason, it has been referred to as the “trucker” of all minerals. Without plant available calcium, a farmer cannot achieve maximum yield
-
Calcium also improves soil structure, tilth and aeration, encourages root growth, builds strong cell walls, facilitates nitrogen-fixing bacteria, increases disease resistance and stimulates beneficial soil microbes.
-
Calcium strengthens the cell walls of plants. It activates enzymes and is a structural component of cell walls.
-
It Influences water movement in cells and is necessary for cell growth and division.
-
Some plants must have calcium to take up nitrogen and other minerals.
-
Calcium, once deposited in plant tissue, is immobile (no translocated) so there must be a constant supply for growth.
