In the 1940s in agricultural practice the agrotechnical measure of weed flaming was introduced (Lague et al., 1997). In many studies flaming has proven effective for weed control in field corn (Ellwanger et al., 1973), cabbage (Bond and Grundy, 2001), carrots and onions (Rifai, 1994). The aim of this paper was to determinate the effect of different propane dozes in weed flaming in soybean and corn crop on the number of systemic group of microorganisms in soil. The soil samples for microbial analysis were taken between the rows, from 2cm depth, 1h and 24h after flaming. Determination of systemic group of microorganisms was done by the method of colony forming unit (CFU) on selective nutrient mediums (Jarak i Đurić, 2006). The most sensitive group of microorganisms on weed flaming, as an agrotechnical measure, was the group of bacteria, the most tolerant were fungi in both investigated crops.
