Petro 333 Ferro+ 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 333 Ferro+ performs a “desalinating” and “unlocking” action towards nutrients, improving the chemical and physical properties of the soil. Petro 333 Ferro+ is distinguished by a high content of particularly bio-available iron and ndicated whenever phenomena predisposing to iron chlorosis arise (e.g. excessive presence of limestone, alkaline pH). Moreover, Petro 333 Ferro+ s 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 333 Ferro+ effectively nourishes the plant, favouring the beneficial microbial activity of the soil.
