Zykal supplements in a targeted and rapid manner the nutritional requirements of crops in terms of Calcium and Zinc. The product performs a dual actions, both on the plant and on the soil. Zykal accelerates cell multiplication, especially of apical meristems and growing organs, while promoting the synthesis of tryptophan, a pre-cursor of auxins, which results in greater growth of buds and fruits. Thanks to the high Calcium content, Zykal improves the production of pectins, which results in increased resistance to post-harvesting fruit handling. Finally, Zykal improves the chemical and physical characteristics of the soil thanks to Calcium, which removes sodium from mineral colloids, performing a desalination and structuring action.
