TheCa is a unique product with high calcium and amino acid content that can be easily absorbed by the plant and rapidly transported between cells. Calcium is a non-mobile element. Its movement inside the plant occurs by a passive mechanism through water movement. When stomata open in the plant, transpiration starts and water is drawn up. Therefore, calcium is also drawn upward. If stomata are closed, there is no transpiration and calcium is not transported, so calcium deficiency mostly occurs in winter months when stomata are closed and at very high temperatures. Amino acids have been added to TheCa to open stomata. Thanks to these amino acids, stomata open even if the air is closed (cloudy). The plant starts to transpire. Calcium is also transported by water movement.
