For the acid soils in the south of the country, it is more than necessary to apply calcareous amendments. Results in this sense were obtained over the years at the main crop plants in the station area. Considering the increasing importance of the soybean crop, it was considered necessary to resume these types of research, as new products based on limestone and dolomite appeared. Significant results were obtained by forming the total biomass of the plant as well as its components. In the case of the Cristina TD (00) variety, the interaction between several CaCOɜ formulations and NP fertilizers contributed as follows: plant biomass 6.46 t/ha (100%), pod biomass 4.16 t/ha (63%), and grains were 2.17 (33%). Of the two analyzed factors, NP fertilizer had the most important contribution to this variety, followed by the influence of the four CaCOɜ formulations. The interaction between the two factors was always negative demonstrating that there was some competition between the cations. The obtained correlations were in all cases positive, but of different intensities. Through the obtained results, it is recommended that new formulations of CaCOɜ be permanently used in the soybean cultivation technology on acid soils.
