Following recent research, the positive influence of calcium on soybean plants, especially on varieties with improved genetic qualities, was found. The results obtained on the plants were significant both on the total biomass of the plants and its components. In our ecological conditions with stagnant white luvic soil (pH = 5.0-5.5) different types of CaCO3 were used to primarily improve the chemistry of the plant culture medium. In the case of the variety Isa TD (group 00), the interaction between CaCO3 and NP fertilizers contributed to a maximum increase of 5.48 t/ha total biomass, 3.44 t/ha pod biomass and 1.47 t/ha of biomass grains. Of the two factors, the new formulations of CaCO3 had the greatest influence, and the interaction with NP was in all cases negative. The correlations obtained between the studied characters were significantly positive, except for the mass of one thousand grains (MTG). The obtained results invite the promotion of soybean crop technology, including the amendment system regarding this type of soil.
