Petro 850 + 2 MgO Fast is an organo-mineral fertiliser developed from the processing of carefully selected raw materials in order to achieve a planned release of nutrients. They are characterised by different net mineralisation rates. Petro 850 + 2 MgO Fast provides Calcium and Magnesium, two key nutrients for plant metabolism. Calcium has both a nourishing action and improves the chemical-physical characteristics of the soil, thanks to which Petro 850 + 2 MgO Fast has a ‘desalinising’ and ‘unblocking’ effect on nutrients. Moreover, Magnesium improves the photosynthetic efficiency of the crop. Finally, Petro 850 + 2 MgO Fast is enhanced by the presence of RyZea, a unique technology that enriches the product with phytostimulant molecules that improve root development, the rate of nutrient uptake and crop productivity.
