A titanium-containing formulation contains complexes of titanium salts with an ascorbic acid and a citric acid, a preservative agent, and water-soluble sulfates of metals absorbable by plants, and optionally additional plant nutrients, in particular nitrogen and potassium. The titanium-containing formulation is a product of titanium complexation reaction of titanyl sulfate with a mixture of ascorbic acid and citric acid in aqueous environment alkalized with magnesium hydroxide in presence of acetic acid, at a mass ratio of magnesium, calculated as MgO, to titanium amounting from 1:1 to 20:1. Furthermore, in the titanium-containing formulation a mass ratio of the ascorbic acid to the citric acid amounts from 5:1 to 3:5, a mass ratio of the ascorbic acid to titanium amounts from 7:2 to 10:1, and a mass ratio of the magnesium hydroxide, calculated as MgO, to the acetic acid, calculated as 100% of the acetic acid, amounts from 8:1 to 3:5.
