Petro Start is an organo-mineral fertiliser made from high-quality raw materials that have been carefully selected to produce a planned release of nutrients. They are characterised by different net mineralisation rates. Petro Start is a highly humified and stabilised product, thanks to the transformation process that the valuable organic material undergoes only in Agriges plants. Thanks to this, Petro Start is characterised by a composition rich in humic and fulvic acids and an optimal C/N ratio. Finally, Petro Start is enhanced by the presence of Calcium, an important meso-nutrient for plant nutrition and for improving soil characteristics, and RyZea, an exclusive technology that enriches the product with phyto-stimulant molecules that improve root development, the share of absorbed nutrients and crop productivity.
