“…Goforth et al (2005) obtained rather low values for white ash (0.69 and 0.39%), and relatively low values for black ash (4.83 and 6.63%) for ash, collected, respectively, after a severe wildfire in a conifer forest and in a pine-oak woodland. For different types of straw burned in the open on large metal trays, Raison and McGarity (1980) reported ash TOC values of 2.5% and 14%. Burns (2007), for ash generated experimentally in a barrel using wood from conifer trees, measured 47-66% TOC.…”

“…These changes in the soil environment may have effects on the soil temperature and consequently on the microbiological activity, since most biological reactions are related to the temperature. Warmer soils after the fire increase the rates of microbiological processes, such as organic matter decomposition and nutrient release, important to plant recovery (Badia and Marti, 2003;Dooley and Treseder, 2012;Hart et al, 2005;Raison and McGarity, 1980). The change in environmental conditions, together with the nutrient availability, rainfall amount after the fire, and warmer temperatures during the spring season, can explain the fact that 2 months after the fire vegetation recovered completely in this burned area.…”

Abstract.Fire is a natural phenomenon with important implications on soil properties. The degree of this impact depends upon fire severity, the ecosystem affected, topography of the burned area and post-fire meteorological conditions. The study of fire effects on soil properties is fundamental to understand the impacts of this disturbance on ecosystems. The aim of this work was to study the short-term effects immediately after the fire (IAF), 2, 5, 7 and 9 months after a low-severity spring boreal grassland fire on soil colour value (assessed with the Munsell colour chart), soil organic matter content (SOM) and soil water repellency (SWR) in Lithuania. Four days after the fire a 400 m 2 plot was delineated in an unburned and burned area with the same topographical characteristics. Soil samples were collected at 0-5 cm depth in a 20 m × 20 m grid, with 5 m space between sampling points. In each plot 25 samples were collected (50 each sampling date) for a total of 250 samples for the whole study. SWR was assessed in fine earth (< 2 mm) and sieve fractions of 2-1, 1-0.5, 0.5-0.25 and < 0.25 mm from the 250 soil samples using the water drop penetration time (WDPT) method. The results showed that significant differences were only identified in the burned area. Fire darkened the soil significantly during the entire study period due to the incorporation of ash/charcoal into the topsoil (significant differences were found among plots for all sampling dates). SOM was only significantly different among samples from the unburned area. The comparison between plots revealed that SOM was significantly higher in the first 2 months after the fire in the burned plot, compared to the unburned plot. SWR of the fine earth was significantly different in the burned and unburned plot among all sampling dates. SWR was significantly more severe only IAF and 2 months after the fire. In the unburned area SWR was significantly higher IAF, 2, 5 and 7 months later after than 9 months later. The comparison between plots showed that SWR was more severe in the burned plot during the first 2 months after the fire in relation to the unburned plot. Considering the different sieve fractions studied, in the burned plot SWR was significantly more severe in the first 7 months after the fire in the coarser fractions (2-1 and 1-0.5 mm) and 9 months after in the finer fractions (0.5-0.25 and < 0.25 mm). In relation to the unburned plot, SWR was significantly more severe in the size fractions 2-1 and < 0.25 mm, IAF, 5 and 7 months after the fire than 2 and 9 months later. In the 1-0.5-and 0.5-0.25 mm-size fractions, SWR was significantly higher IAF, 2, 5 and 7 months after the fire than in the last sampling date. Significant differences in SWR were observed among the different sieve fractions in each plot, with exception of 2 and 9 months after the fire in the unburned plot. In most cases the finer fraction (< 0.25 mm) was more water repellent than the Published by Copernicus Publications on behalf of the European Geosciences Union. P. Pereira et al.: Sho...
