Abstract: The aim of the present study was to evaluate the use of Phytotoxkit biotest to determine the effect of humic and mineral soils fertilization with variable doses of calcium-organic Biocal preparation. To verify the effect of fertilizer the analysis of Biocal impact on physicochemical properties was executed. An increase of calcium content, decrease of hydrolytic acidity and increase of sorption capacity in both soil samples was ascertained. The research of seed germination index SG showed that only small doses of fertilizer (up to 0,5 g) had a positive effect on the test plants. In comparison to non-fertilized soils the 0,5 g dose of Biocal in humic soil and 0,25 g in mineral soil was beneficial with respect to root growth stimulation, as RI index reached negative values.
