Petro 855 CS is an organo-mineral fertilizer which is created from the processing of premium raw materials, carefully selected to gradually nourish the plant, stimulate telluric microorganisms and improve the chemical, physical and biological characteristics of the soil. Petro 855 CS, in fact, performs a planned nutrient release, thanks to raw materials characterised by different net mineralisation rates. In addition, the product’s highly humified organic matter performs a dual function: it reduces losses of fertiliser units and performs a ‘desalinising’ and ‘unblocking’ activity towards nutrients already present in the soil. Finally, Petro 855 CS is enhanced by the presence of RyZea, an exclusive technology that enriches the product with phytostimulating molecules which improve root development, the amount of nutrients absorbed and productivity of the crops.
