Oligodynamic essences complex, with stimulating action and viable functions developing of vegetative systems. The fertilizing product even in small quantities is able to enrich the soil nutritive solution, increasing the enzymes forming, which catalyse the metabolic reactions. The complex action is carried on, in a synergistic way, both in active transport toward roots (diffusion on the plasmatic membrane), and in the leaves, leading to a multiplication of the active photosynthesis centres and active centres (with a greater development of plastocyanin and ferredoxin).
