Controlled Release of Magnesium
CR-MAG™ is the only magnesium controlled-release magnesium fertilizer according to the plant’s needs. Its specific formulation containing 60% MgO combines a very high bioavailability and limited magnesium leaching while offering perfect stability in blends. The release is controlled by the plants which, during the growth phase, release organic acids into the soil which cause the degradation of CR-MAG™ into Mg2+ ions assimilated by the roots.
