Petro 3-6-12 + 2 MgO is an organo-mineral fertilizer that arises from the processing of fine raw materials carefully selected to determine a planned nutrient release. In fact, they are characterized by net mineralization rates. Petro 3-6-12 + 2 MgO provides more Potassium and Sulphur, two fundamental elements that perform important nutrient and metabolic functions: Potassium regulates cellular osmotic pressure while Sulphur is a natural acidifier that “unblocks” soil nutrients and improves soil chemical-physical characteristics. Finally, Petro 3-6-12 + 2 MgO is enhanced by the presence of Magnesium, an element that improves the photosynthetic efficiency of the crop, and by RyZea, an exclusive technology that enriches the product of phytostimulant molecules.
