Abstract: Experiment was carried out in the Experimental Station of Aleksandras Stulginskis University in 2012-2013. The soil type Calc (ar) i-Endohypogleyic Luvisol. Factor A of the experiment – weed control methods: 1) Thermal (T); 2) Mechanical (M); 3) Suppression (S). Factor B - biological methods: 1) Used biological preparations (With BP); 2) Not used biological preparations (No DB). All examined non-chemical weed control methods had no significant effect on the activity of saccharase. The urease activity was significantly higher in plots where thermal weed control method was used compared with this in plots where mechanical weed control method and weed suppression was used. The tendency of higher soil enzymes activity was established in plots without biological preparations. The mechanical weed control method substantially reduced CO2 emissions. Significantly lower CO2 emission was investigated in plots with mechanical weed control. Significantly higher CO2 emission was investigated in plots without biological preparations
