Petro NP 6-18 is an organo-mineral fertiliser made from high-quality raw materials that have been carefully selected to result in a planned release of nutrients. They are characterised by different net mineralisation rates. Petro NP 6-18 is a product highly humified and stabilised thanks to the maturation process it undergoes only in Agriges’ factories. Thanks to this, Petro NP 6-18 is characterised by a composition rich in humic and fulvic acids and an optimal C/N ratio. Finally, Petro NP 315 is enhanced by the presence of RyZea, an exclusive technology that enriches the product with phytostimulant molecules that improve root development, nutrient uptake and crop productivity.
