Petro 450 Zn is an organic fertilizer that gives nutrients to plants in a balanced and constant manner over time. The premium raw materials are carefully selected to determine a programmed release of the nutrients, since they are characterized by different net rates of mineralization. Petro 450 Zn contains highly humified organic substance and free amino acids able to catalyse many enzymatic processes (photosynthesis, cellular turnover, and phytoalexin production). Petro 450 Zn contains a good amount of Zinc, an essential element to promote an optimal development of the root system and biofortify the plant to temperature changes. Furthermore, Petro 450 Zn is enhanced by RyZea, an exclusive technology that enriches the product with phytostimulant molecules to improve root development, the share of absorbed nutrients and crop productivity.
