Abstract: The model field experiments carried out in Experimental Station of Aleksandras Stulginskis University in 2015–2016. Researches aim to identify and assess the impact of biological preparations and organic fertiliser (slurry) on soil properties (temperature and electrical conductivity) and CO2 emissions after different periods of time: 1) after measures application (beginning of experiment); 2) after 2 months (in autumn); 3) after 7 months (in spring). It was estimated that at the beginning of the model field experiment biological preparations and organic fertiliser application had no significant effect on soil temperature and CO2 emissions in autumn at the beginning of the experiment and after 2 months of measures application. In spring, after 7 months of measures application soil temperature was significantly higher in treatment where organic fertiliser with biological preparation (SBio2) was used to compare with control and soil treated with biological preparation (Bio1). Soil electrical conductivity at the beginning of the model field experiment after measures application was significantly lower, but CO2 emissions was significantly higher in the treatments were organic fertiliser was applied with (SBio2) and without biological preparation (S) to compare with control and soil treated with biological preparation (Bio1). In spring, after 7 months of measures application soil electric conductivity was significantly higher in treatment where organic fertiliser with biological preparation (SBio2) was used to compare with other treatments. CO2 emissions were higher in treatments where biological preparations were used to compare with control and slurry (S). Evaluating all experimental period was estimated correlation between the CO2 emissions rate and temperature after 2 (r=0.45) and 7 (r=0.66) months of measures application
