Do stones modify the spatial distribution of fire induced soil water repellency? Preliminary data
Creators
Description
Water repellency is a property of many fire-affected soils that contributes to delayed wetting rates and
shows many hydrological and geomorphological consequences. Fire-induced soil water repellency (SWR)
may be modulated by pre-fire soil and vegetation properties. Many studies have been carried out to
investigate the relationship between SWR and these properties. But, to our knowledge, no studies have
considered the effect of surface stones in the spatial distribution of fire-induced SWR. In this research, we
study the occurrence and spatial and vertical distribution of SWR and its consequences on soil structure
after experimental burning in a previously wettable soil under different stone covers (0, 15, 30, 45 and
60%). In our experiment, burning induced critical or subcritical SWR in the upper millimetres of previously
wettable soil. Fire-induced SWR did not vary with stone cover, but critical SWR was reached in inter-stone
soil areas. At stone-covered soil areas, SWR was increased, but WDPTs remained mostly below the 5 s
threshold
