Popis:	Changes in soil properties, soil organic C (SOC) and total nitrogen (TN) stocks associated with different heating temperatures from 50, 100, and 150 kg/m dry biomass that provided for different heat intensities were compared with natural soil temperature of continuous cultivated arable land adjacent to the burnt plots. Soil samples were collected in three replicates from control and burnt plots and soil temperatures were measured with fire resistance soil thermometer placed at surface and sub-surface layers, while gases emission were measured with sensitive gas dictators. The induced temperatures were highly variable at the soil surface whereas below 15cm depth, the temperature rise was not more than 37C. The passage of fire promoted SOC and TN stocks, mean weight diameter, the aggregation of 2 mm stable structures which become even more resistant to disrupting action of water. Air quality measurement revealed that NO2, SO2 H2S and CO2 were above the Federal Ministry of Environment & Protection (FME&P) permissive limits indicating air pollution through these activities.
