The effect of different doses of amphibolite rock dust on selected physical and chemical properties of poor podzolic forest soils after 100-day incubation of soil samples was studied in laboratory conditions. The rock dust with 42 % rate of fractions under 0.05 mm was used in the test. The tested rock flour showed a wide range of positive ameliorative and fertilizing effects: reduction of soil acidity, import of mineral nutrients, especially Ca and Mg, increase of basic cations content, increase of adsorption exchange capacity and base saturation percentage, support of biological activity affecting humification and nitrification of organic matter, etc.
