COMPOSITION FOR THE TREATMENT OF PLANTS AND ITS USES

摘要

A diluted aqueous solution containing less than 80 g/l of magnesium carbonate acid of formula Mg(HCO3)2 can be used for curing plants suffering from a magnesium deficiency or, as a preventative measure, as a magnesium fertiliser complement and as a photosynthetic plant growth activator by simply being sprayed onto said plants. An aqueous magnesium carbonate acid solution Mg(HCO3)2 is prepared using, as its base, MgO, which is mixed in water; the resulting solution or suspension is then treated with gaseous carbonic anhydride, at a temperature lower than 40.degree.C and a pressure higher than 5.105 Pa (5 bars).
