“…SWR is caused by organic compounds derived from living or decomposing plants or micro-organisms, wildfire ash and treated wastewater application Schacht et al 2014;Tinebra et al 2019). It is influenced by soil temperature (Novák et al 2009), moisture (Oostindie et al 2017;Leelamanie and Nishiwaki 2019), texture (Benito et al 2019), pH (Diehl et al 2010), soil organic carbon (SOC) and clay (mainly kaolinite) content (Lichner et al 2002). SWR generally increases during dry summer conditions, while it is reduced or completely eliminated after prolonged and/or heavy precipitation (Taeumer et al 2006;Orfánus et al 2016).…”

Evaporation from soils of different texture covered by layers of water repellent and wettable soils

Water repellent soils are able to channel water deep into the soil profile by fingered flow, minimising water storage in the water repellent top layer where water is most susceptible to evaporation. To date, the effect of water repellent or wettable surface layer on evaporation from wet sublayer has only been reported for coarse materials, and an increase in water repellency led to a greater delay in water evaporation. The objective of this study was to assess the effect of water repellent vs. wettable top layers with different thickness on water evaporation from coarse and fine texture subsoils that were pre-moistened. Clay loam soil samples were taken from Pinus pinaster woodland of Ciavolo, Italy, and sandy soil samples from Pinus sylvestris woodland of Sekule, Slovakia. Evaporation from soil samples was determined from the loss of weight in laboratory conditions. Water in the clay loam soil from Ciavolo was held for a longer period due to slower evaporative loss than in the sandy soil from Sekule, and the impact of the water repellent layer on the loss rate over time is related to its thickness. Over 550 hours, about 90% of the initial stored water was evaporated from the 1 uncovered clay-loam soil sample from Ciavolo. In the same time, the 0.3, 1, and 2 cm-thick duff layers, respectively, saved about 23, 34, and 58 % of water from evaporation, and evaporation of 90% of water took over 780, 1100, and 1450 hours. It means that the clay loam soil cover with the 0.3, 1, and 2 cm-thick duff layers resulted in prolonging the evaporation by 10, 23, and 37.5 days, respectively. As to the sandy soil from Sekule, 98% of water was evaporated from the uncovered soil sample over 240 hours. In the same time, the 0.3, 1, and 2 cm-thick water repellent soil layers, respectively, saved about 7, 45, and 59 % of water from evaporation, and evaporation of 98% of water took over 330, 606, and 774 hours. It means that the sandy soil cover with the 0.3, 1, and 2 cm-thick water repellent soil layers resulted in prolonging the evaporation by about 4, 15, and 22 days, respectively. It can be concluded that water repellent surface layers, created by pine trees, are able to delay evaporation significantly for both coarse and fine textured soils, which may be particularly beneficial for plants during hot and dry periods in summer.

“…Vegetation change can also induce soil water repellency (SWR), which parameters are influenced by soil temperature (Novák et al, 2009), moisture (Leelamanie and Nishiwaki, 2019;Oostindie et al, 2017), texture (Benito et al, 2019), pH (Diehl et al, 2010), soil organic carbon (SOC) and clay (mainly kaolinite) content (Lichner et al, 2002). SWR may affect soil properties with depth (Orfánus et al, 2016;Sepehrnia et al, 2017) and time (Orfánus et al, 2014;Moret-Fernandez et al, 2019), and has positive effects on the stability of soil aggregates (Fér et al, 2016).…”

Abandonment of agricultural lands in recent decades is occurring mainly in Europe, North America and Oceania, and changing the fate of landscapes as the ecosystem recovers during fallow stage. The objective of this study was to find the impact of secondary succession in abandoned fields on some parameters of acidic sandy soils in the Borská nížina lowland (southwestern Slovakia). We investigated soil chemical (pH and soil organic carbon content), hydrophysical (water sorptivity, and hydraulic conductivity), and water repellency (water drop penetration time, water repellency cessation time, repellency index, and modified repellency index) parameters, as well as the ethanol sorptivity of the studied soils. Both the hydrophysical and chemical parameters decreased significantly during abandonment of the three investigated agricultural fields. On the other hand, the water repellency parameters increased significantly, but the ethanol sorptivity did not change during abandonment. As the ethanol sorptivity depends mainly on soil pore size, the last finding could mean that the pore size of acidic sandy soils did not change during succession.

“…On the other hand, SWR can be a potential driver of vegetation dynamics in coastal dunes (Siteur et al, 2016) and has positive effects on the stability of soil aggregates (Fér, Leue, Kodešová, Gerke, & Ellerbrock, 2016;Goebel, Bachmann, Woche, & Fischer, 2005), thereby reducing evaporation (Bachmann, Horton, & van der Ploeg, 2001;Rye & Smettem, 2017). SWR can develop in soils of varied textural composition, but it is most common in sandy substrates (Lichner et al, 2010;Oostindie, Dekker, Wesseling, Geissen, & Ritsema, 2017;Wang, Zhao, & Horn, 2010;Woche et al, 2005).…”

Effect of vegetation and its succession on water repellency in sandy soils

et al. 2018

Vegetation and its succession can change the parameters of soil water repellency (SWR) due to the change in amount and composition of soil organic matter. This hypothesis was tested in natural and agricultural environments in Germany, Hungary, and Slovakia. The parameters investigated were the extent (determined by the repellency indices RI, RIc, and RIm) and persistence (determined by the water drop penetration time and water repellency cessation time) of SWR, as well as the potential wettability index of organic matter in sandy soils. The SWR parameters and soil organic carbon (SOC) content increased in the course of primary succession at Mehlinger Heide, Germany, and Sekule, Slovakia. Dye tracer experiments undertaken at Sekule revealed contrasting flow patterns: (a) preferential flow in water‐repellent soil under biological soil crust and grass and (b) piston flow in wettable soil that consists almost of pure quartz sand. The effective flow cross section decreased, and the degree of preferential flow increased in the course of primary succession at Sekule. No consistent trend of the SWR parameters and SOC was observed in the course of secondary succession at Csólyospálos, Hungary. This is the first time that differences between trends in SWR parameters due to primary and secondary successions were observed and related to the composition of SOC and extracellular polymeric substances. It can be concluded that dynamics of soil organic matter composition during the succession controls SWR.
