Petro 390 Plus is an organo-mineral fertilizer that nourishes plants in a balanced and constant way over time. The precious raw materials of which the product is composed are carefully selected to determine a programmed release of nutrients. In fact, they are characterized by different net mineralization rates and perform a “desalination” and “unblocking” action on nutrients, improving the chemical-physical properties of the soil. Furthermore, Petro 390 Plus is enriched by the presence of RyZea, an exclusive technology which enriches the product with phytostimulant molecules which improve root development, the amount of nutrients absorbed and the productivity of the crop. Petro 390 Plus effectively nourishes the plant, promoting the beneficial microbial activity of the soil.
