“…The soil at this site is a Sparta sand, a mixed, mesic Entic Hapludoll (Soil Survey Staff, 2013). The soil texture is sand, and drainage is excessive (Hart et al, 1994;Flores-Mangual et al, 2013). The climate is humid continental, with high seasonal temperature variations.…”

“…Also in Australia, the results from multiple studies in deep sandy soils have shown that wetting fronts move significantly more slowly in soils under pine plantations than in soils under shrubs (Le Maitre et al, 1999). Another effect of vegetation on soil water is the formation of soil water repellency in some vegetation types (Buczko et al, 2005;Doerr et al, 2009;Flores-Mangual et al, 2013).…”

“…Scott (2000) found that native grassland soils in South Africa were less hydrophobic than indigenous forest and pine plantations. Likewise, in Wisconsin, it has been documented that there is greater soil water repellency in areas planted with pines than in prairie soils (Richardson and Hole, 1978;Flores-Mangual et al, 2013).…”

“…In particular, in the LWRV there was an increase in soil water repellency intensity in areas converted from prairie to pine plantation (40-yr-old plantation) (Flores-Mangual et al, 2013). The pine plantation exhibited extreme soil water repellency (water drop penetration time [WDPT] average of 3308 s) at the soil surface, significantly greater than the prairie (WDPT average of 1907 s).…”

Vegetation can directly affect soil water dynamics through rainfall interception and evapotranspiration. Vegetation type probably is one factor that causes soil hydrophobicity, and hydrophobicity can influence water infiltration and groundwater recharge. Surfactants can be used to alleviate non-wetting conditions. The objectives of this study were to determine the effects of vegetation type on soil water content and groundwater recharge and to explore if a soil-applied surfactant can increase both conditions. The research was located in the Lower Wisconsin River Valley (LWRV), on Sparta sand with three different vegetation ecosystems: prairie, pine plantation, and mixed prairie and forest (mixed vegetation); hydrophobicity has been found to be pronounced under pine plantations in the LWRV. Soil water content was monitored at three depths (5, 25, and 70 cm) with time domain reflectometry. Groundwater recharge was assessed by monitoring wells equipped with pressure transducers. Rain gauges and weather stations were installed to measure precipitation and air temperature. Soil core samples were collected for tests of saturated hydraulic conductivity (K s ) and bulk density (D b ). Surfactant was applied on half of the plots after collecting several years of background data. There was significantly less soil water under the pine plantation than the prairie and mixed vegetation. Groundwater recharge did not vary among vegetation types, probably because differences were obliterated due to high aquifer transmissivity. The pine plantation had less profile drainage; however, the surfactant did not increase profile drainage. There were no differences in K s and D b . The conversion from prairie to pine plantation resulted in reduced soil water content and drainage.

“…It has been very frequently reported in literature over the last years that coniferous forest litter causes the strongest levels of SWR (e.g. de Blas et al, 2013;Flores-Mangual et al, 2013;Lozano et al, 2013), most probably due to high content of hydrophobic resins, terpens, and waxes.…”

Soil sorptivity is considered a key parameter describing early stages of water (rain) infiltration into a relatively dry soil and it is related to build-up complexity of the capillary system and soil wettability (contact angles of soil pore walls). During the last decade an increasing water repellency of sandy soils under pine forest and grassland vegetation has been frequently observed at Mlaky II location in SW Slovakia. The dry seasons result in uneven wetting of soil and up to hundredfold decrease in soil sorptivity in these vegetated soil as compared to reference sandy material, which was out of the reach of ambient vegetation and therefore readily wettable. As far as water binding to low moisture soils is governed by adsorption processes, we hypothesized that soil water repellency detected by water drop penetration test and by index of water repellency should also influence the water vapour adsorption parameters (monolayer water content, W m , specific surface area, A, maximum adsorption water, W a , maximum hygroscopic water M H , fractal dimension, D S and adsorption energies, E a ) derived from BET model of adsorption isotherms. We found however, that the connection of these parameters to water repellency level is difficult to interpret; nevertheless the centres with higher adsorption energy prevailed evidently in wettable materials. The water repellent forest and grassland soils reached less than 80% of the adsorption energy measured on wettable reference material. To get more conclusive results, which would not be influenced by small but still present variability of field materials, commercially available homogeneous siliceous sand was artificially hydrophobized and studied in the same way, as were the field materials. This extremely water repellent material had two-times lower surface area, very low fractal dimension (close to 2) and substantially lower adsorption energy as compared to the same siliceous sand when not hydrophobized.
