Carbon dioxide is one of the most important greenhouse gases. Agriculture, especially soil tillage, contributes to CO<sub>2</sub> emissions significantly. The aim of the paper was the comparison of the amounts of carbon dioxide emissions released from the soil into the atmosphere depending on the controlled traffic farming (CTF) and crop residues. Three variants of the experiment were realised: before the soil tillage, immediately after the soil tillage, and seven days after the soil tillage. The soil tillage was carried out after the harvest of winter wheat by disc harrow Lemken Rubin 9 with a tractor John Deere 8230 on the loamy soil. The monitoring points were selected in parts of the field with and without the crop residues and in trafficked and non-trafficked areas. The CTF system affects CO<sub>2</sub> flux, the amounts of emissions from the non-trafficked areas being higher than those from the trafficked areas. The crop residues left on the field cause a decrease of CO<sub>2</sub> flux. The incorporation of crop residues causes an increase of CO<sub>2</sub> flux.

Today's global challenge is the increasing concentration of carbon dioxide (CO2) and other greenhouse gases in the air. The level of CO2 emissions may be significantly affected by the agriculture and, more specifically, the applied tillage method, even though to a lesser extent than industrial production. On a global scale, the CO2 emission of an agricultural area is insignificant in comparison to that of a large-scale plant in an area of the same size, but areas under cultivation, including arable land, have a large global area. In this paper, we investigated the relationship between applied soil tillage methods and carbon dioxide emissions in the case of different fertiliser treatments. In our experiment we examined four types of tillage with five different fertiliser effects. Comparing fertiliser treatments and tillage methods, it was found that their interaction significantly affected carbon dioxide emissions, the lowest value was obtained in the case of the 210 l ha-1 Nitrosol+N-LOCK – tillage radish treatment. Strip and tillage radish methods have relatively homogeneous, low value.
