dc.description.abstractSoils affected by forest wildfires in Russia in 2010 were studied in postfire and unburned plots near Togljatty city, Samara region. The microbial biomass, basal respiration of the soil, and the ash composition dynamics were investigated under the effect of forest fires during the 3 years at the site of a surface forest fire, a crown forest fire site, and a site unaffected by fire as a control (unburned). Soil samples were collected at 0–15 cm. The analytic data obtained showed that wildfires led to changes in the chemical composition of soil horizons and increased their ash content. Fires led to the accumulation of nutrients (P and K) in the fine earth of the soil. Thus, when the upper horizons are burned, the ash arriving on the soil surface enriches it with nutrients. The calcium content was also increased, leading to an alkaline pH of the upper soil horizons. The values of nutrients decreased as a result of leaching out with a precipitation during the second year after the fire. The unburned soils were characterized by the greatest values of microbial biomass carbon in the top horizon and the biggest values of basal respiration, whereas both parameters decline in postfire soils. Nevertheless, this influence did not extend to depths [10 cm. Thus, the effects of fire on soils were recognized as a decrease of microbiological activity.en_GB
