MgO 10 – 250ml


Bio Nova’s MgO is a food-grade mineral fertilizer with 10% magnesium. Magnesium is essential for photosynthesis and for the formation of reactive chlorophyll nuclei. Bionova MgO 10 should be used mainly in case of deficiencies, since the Bionova main line already contains the right amounts of magnesium.

A magnesium deficiency is manifested in chlorosis (slight discoloration) between the nerves of old leaves. An excess results in a poorly grown crop and small leaves! Plants directly absorb all food-quality minerals giving you optimal control of your crop. The magnesium in Bionova MgO 10 forms the reactive nuclei of chlorophyll, which converts light energy into chemical energy (ATP and ADP).

How Is Bionova MgO 10 Used?

  • It must be applied when deficiencies occur and to stabilize osmose water
  • It can be mixed with all Bionova fertilizers, stimulators, minerals, universals and substrates.
  • It can be used as irrigation and as a foliar spray.
