The presence of crop residue on the soil surface has an impact on evaporation, water storage, soil temperature and soil heat flux. Consequently, changes the energy transfer in the soil-atmosphere system. The objective of this work is study the influence of crop residues in the soil thermal variables. It was concluded that the thermal effect of a straw layer is large, leading to surface temperature differences around 10°C. With depth increasing, the effect of straw coverage decreases, leading to a temperature difference to 4°C of 5cm depth. The most important consequence of higher temperature on bare ground is an increase of soil heat flux. In stable weather conditions, this difference can reach 29 W/m2.
