Product designed to be used for the preventive and curative control of deficiency states due to imbalances or deficiencies in the assimilation of calcium. The presence of high quality amino-acids, other organic compounds and boron, favors the assimilation through the foliage and the roots, translocation inside the plant and calcium storage in fruits. Calcium is an immobile element. Its mobility in the plant is caused by the passive mechanism the movement of the water. When the stoma in the plant opens up, perspiration starts and the water is pulled upwards. If the stoma remains closed, perspiration does not occur therefore the calcium does not move.
