Micro-element and macro-element deficiency correctors for crops: Cu, Mg, Zn, Fe, Mn and Ca. Nutrients are complexed, thereby improving their absorption and distribution and permanence within the plant, improving bio-availability. Through application of our own technology we achieve a high concentration of complexed element with balanced molecular weight. Readily miscible in water. Decreases the surface tension of pulverised water, thereby improving its distribution on the leaf surface. High compatibility with other products that may be applied simultaneously.
