The invention relates to plant conditioning compositions containing titanium, which have an increased physico-chemical and biological stability. The compositions comprise 0.1 to 15.0% by weight of a titanium- ascorbic acid chelate containing 14 to 28 g.moles of ascorbic acid related to 1 g.atom of titanium, the pH of which is adjusted to 5 to 7, 0.1 to 2.0 parts of one or more biochemically essential nutrients and/or 0.0001 to 0.001 parts of one or more phytohormones related to 1 part of titanium and at least 0.01% by weight of one or more of the compounds selected from the following group: sorbic acid and salts thereof, benzoic acid and salts thereof, p-nitro-benzoic acid and salts thereof, propionic acid and salts thereof, hexamethylenetetramine related to the total weight of solid ingredients, optionally in association with wetting agents, adhesives and/or further conventional additives. <IMAGE> |
