| Summary: | Two fire-affected soils were studied using
micromorphological methods. The objective of the paper is to assess and
compare fire effects on the micropedological organisation of soils in a forest-steppe zone of central Russia (Volga Basin, Togliatti city). Samples
were collected in the green zone of Togliatti city. The results showed that
both soils were rich in quartz and feldspar. Mica was highly present in soils
affected by surface fires, while calcium carbonates were identified in the
soils affected by crown fires. The type of plasma is humus–clay, but the soil
assemblage is plasma–silt with a prevalence of silt. Angular and
subangular grains are the most dominant soil particulates. No evidence of
intensive weathering was detected. There was a decrease in the porosity of soils affected by fires as a consequence of soil pores filled with ash and
charcoal. |
