Fire-induced changes in soil properties depend on age and type of forests

Abstract Wildfires affect different physical, chemical, and hydraulic soil properties, the magnitude of their effects varies depending on intrinsic properties wildfire characteristics. The objectives this study are: to estimate impact heating temperature (50–900°C) sandy (Arenosol) taken in 1) coniferous forests (Scots pine Pinus sylvestris ) ages (30 100 years); 2) deciduous (alder Alnus glutinosa same age years). are located central part Borská nížina lowland (western Slovakia), treated were organic carbon content (SOC), pH, water repellency (measured terms drop penetration time, WDPT). It was found that is great depends both type forest. SOC value decreased unevenly with all three soils, it higher 30-year-old forest than soil. pH increased monotonously from 200 °C, 100-year-old WDPT Results obtained (decrease SOC, disappearance SWR after 400 increase °C) bring important information for post-fire vegetation restoration management Central European established
