metadata.value: Soils 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.
