ATTIV 30-20 is a formulation with a high content of phosphorus and potassium in a completely assimilable form and exerts a notable nutritional activity. In addition to preventing nutritional deficiencies, it activates the defense mechanisms of plants in a completely natural way, revitalizing them. In particular, phytoalexins are produced which prevent the development of some pathogenic fungi. The ascending and descending activity of the phosphate ion is systemic and this allows ATTIV 30-20 to strengthen the plant completely.
