Petro 330 Boro + 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. In addition, Petro 330 Boro + is enriched by the presence of RyZea, an exclusive technology that enriches the product with phytostimulant molecules that improve root development, the amount of nutrients absorbed and the productivity of the crop. Petro 330 Boro + is enriched with Calcium, Sulphur and Boron. While Calcium and Sulphur perform a “desalinating” and “unblocking” action towards the nutrients, improving the chemical-physical properties of the soil, Boron is an essential micro-element for flowering and fruit ripening.
