Petro 442 is an organic fertilizer that nourishes plants in a balanced and constant way over time. Its fine raw materials are carefully selected to determine a planned nutrient release, as they are characterized by different net mineralization rates. Petro 442 performs a “desalinating” and “unlocking” action towards nutrients, improving the chemical and physical properties of the soil. Moreover, Petro 442 is enriched by the presence of RyZea, an exclusive technology that enriches the product with phyto-stimulant molecules, which improve root development, the amount of nutrients absorbed and the crop productivity. Finally, Petro 442 effectively nourishes the plant, favouring the beneficial microbial activity of the soil.
