“…Studies suggest that the impact of subcritical WR on water sorptivity, conductivity and infiltration rates is underestimated (Hallett et al, 2001(Hallett et al, , 2004Lamparter et al, 2006;Orfánus et al, 2008) and Lamparter et al (2006) found subcritically water repellent soils to reduce infiltration rates by a factor of 3 to 170. Overall, the degree of WR mainly depends on the soil texture, quantity and quality of soil organic matter (SOM) and the soil water content (Bisdom et al, 1993;Dekker et al, 2001;Graber et al, 2009;Mataix-Solera et al, 2013;Mirbabaei et al, 2013;Nadav et al, 2013;Woche et al, 2005). These factors influence the amount of soil particle surfaces coated with hydrophobic or amphiphilic organic substances, as well as their orientation (Diehl, 2013;Doerr et al, 2000;Graber et al, 2009).…”

“…alkyl chain length, alkyl chain saturation, ionized molecules). This may explain the inconsistent results on whether or not the amount of soil organic matter (SOM) has an influence on the occurrence or severity of WR (Aelamanesh et al, 2014;Eynard et al, 2006;Hajnos et al, 2013;Mataix-Solera et al, 2013;Mataix-Solera and Doerr, 2004;Mirbabaei et al, 2013;Varela et al, 2005;Vogelmann et al, 2013;Woche et al, 2005) and the findings of pronounced differences in the effects of a range of organic molecules on WR (de Blas et al, 2013;Doerr et al, 2000;Fischer et al, 2013;Simkovic et al, 2008). WR can be assessed by means of the water drop penetration time (WDPT) test (e.g.…”

Abstract:The biological soil crusts (BSCs) in the NW Negev cause local water redistribution by increasing surface runoff. The effects of pore clogging and swelling of organic and inorganic crust components were intensively investigated in earlier studies. However, the effect of water repellency (WR) was not addressed systematically yet. This study investigates subcritical WR of BSCs in three different study sites in the NW Negev. For this purpose, three common methods to determine soil WR were used: (i) the repellency index (RI) method (ii) the water drop penetration time (WDPT) test and (iii) the Wilhelmy plate method (WPM). Furthermore, the potential influence of WR on local water redistribution is discussed and the applied methods are compared. We found the BSC to be subcritically water repellent. The degree of WR may only affect water redistribution on a microscale and has little influence on the ecosystem as a whole. The RI method was clearly the most appropriate to use, whereas the WDPT and the WPM failed to detect subcritical WR.

“…But SWR is also present in unburned soils. Recent studies have discussed the origin and characteristics of SWR in unburned forest soils from Iran (Mirbabaei et al ., ), NE Spain (Badía et al ., ), volcanic soils from the Canary Islands (Spain; Neris et al ., ) and Mexico (Jordán et al ., ; Jordán et al ., ), and cropped solis (González‐Peñaloza et al ., ; García‐Moreno et al ., ) and biological soil crusts in Slovakia (Lichner et al ., ) and Israel (Kidron et al ., ).…”

“…In recent years, noteworthy progresses have been carried out in understanding factors affecting SWR. Water repellency is conditioned by soil properties such as organic matter content and quality (Leelamanie and Karube, ; Atanassova and Doerr, ), texture (Roberts and Carbon, ; Giovannini and Lucchesi, ; Mataix‐Solera et al ., ), aggregates (Zavala et al ., ; Jordán et al ., ; Mataix‐Solera et al ., ), acidity and mineralogy of the clay fraction (Dlapa et al ., ; Mataix‐Solera et al ., ; Zavala et al ., ; Mirbabaei et al ., ), microbial activity (Savage et al ., ; Jex et al ., ), water content Poulenard et al ., ; Regalado and Ritter, ; Lichner et al ., ; De Jonge et al ., ) and seasonal variations (De Jonge et al ., ; Doerr and Thomas, ; Leelamanie and Karube, ; Zavala et al ., ; Czachor and Lichner, ).…”

Although fire-induced soil water repellency (SWR) and its effects on soil hydrology and geomorphology have been studied in detail, very few studies have considered the effect of rock fragments resting on the soil surface or partly embedded in soil. In this research, we have studied the effect of rock fragments on the strength and spatial distribution of fire-induced SWR at different fire severities. A fireaffected area was selected for this experiment and classified into different zones according to fire severity (unburned, low, moderate and high) and rock fragment cover (low, <20% and high, >60%). During 7 days after fire, SWR and infiltration rates were assessed in the soil surface covered by individual rock fragments and in the midpoint between two adjacent rock fragments (with maximum spacing of 20 cm). SWR increased with fire severity. Rock fragments resting on the soil surface increased the heterogeneity of the spatial distribution of fire-induced SWR. SWR increased significantly with rock fragment cover in bare areas under moderate and high fire severity, but quantitatively important changes were only observed under high fire severity. In areas with a low rock fragment cover, water repellency from soil surfaces covered by rock fragments increased relative to bare soil surfaces, with increasing SWR. In areas with a high rock fragment cover, SWR increased significantly from non-covered to covered soil surfaces only after low-severity burning. Rock fragment cover did not affect infiltration rates, although it decreased significantly in soil surfaces after high-severity burning in areas under low and high rock fragment cover.

“…Other factors, like fire, may have no impact, destroy or enhance soil WR (Doerr et al ., ; Jordán et al ., ; Pereira et al ., ). Consequently, different authors have investigated the natural soil WR background in different areas as USA (Pierson et al ., ; Doerr et al ., ), Iran (Mirbabaei et al ., ), Mexico (Jordán et al ., ), Spain (Rodríguez‐Alleres et al ., ; Zavala et al ., ), South Africa (Scott, ) or Australia (Blackwell, ).…”

Spatial Gradients of Intensity and Persistence of Soil Water Repellency Under Different Forest Types in Central Mexico

et al. 2016

Organic residues release hydrophobic compounds to the soil that may induce soil water repellency (WR), which may inhibit infiltration and increase runoff and soil loss rates. Although there are many studies on soil WR through the world, very few investigations have been conducted in Mexican areas. This paper studies the natural background of soil WR in soils from central Mexico under representative forest types, analyzing the spatial distribution of soil WR in relation with tree canopy, vegetation cover and main soil chemical (pH, CaCO3, organic C content and exchangeable cations) and physical properties (texture). The water drop penetration time and the ethanol tests were used to assess persistence and intensity of soil WR, respectively. Although soil WR was not related with soil properties, it decreased strongly from soil below the canopy of conifers to soil below oaks. When different types of vegetation cover were considered, the proportion of water‐repellent soil increased following the sequence: bare soil < shrubs and herbaceous plants < shrubs < trees from fir, fir‐pine‐oak and pine‐oak forest. We found an inverse relation with distance to the tree trunks, contributing to create a patchy pattern of soil WR, with soils under the canopy of conifers showing the most severe WR levels. The spatial distribution of soil WR is also conditioned by microclimatic gradients, as persistence and intensity of soil WR were usually lower in shaded areas (upslope transects from the tree trunks), where soil moisture content is expected to be higher on average through the year.
