Soil water repellency has important consequences for ecological and hydrological properties of soils and usually retards infiltration capacity and induces preferential flow. This phenomenon has been known to occur on a wide range of sites under a variety of climatic conditions. The objective of this study was to investigate and characterize soil water repellency on forest sites with identical substrate and climatic conditions, differing in tree age and species. In the Vester Torup Klitplantage, an area comprising a conifer dominated forest plantation stocking on sandy deposits in a coastal setting near the Jammer Bay in north-western Jutland/Denmark, four different forest plots were investigated for water repellency effects four times in 2005. To measure soil water repellency, the water drop penetration time test and the critical surface tension test were carried out. Both tests revealed a seasonal variability in water repellency, exhibiting the highest water repellency for the upper 10 cm of the soil during the summer months, whereas the variability between the different plots seems to be less significant. There was no coherence between humus forms, thickness of litter layer and water repellency.

“…Organic matter has direct impacts on reducing wetting rates or inducing water repellency in soils (Doerr and Thomas 2000;Mataix-Solera and Doerr 2004;Leelamanie and Karube 2007), where the hydrophobic organic matter has greater effect over hydrophilic organic matter. Improving aggregate stability using hydrophobic organic matter is not as simple a process as it appears to be.…”

“…Hydrophobicity can re-appear when soils become dry again. This re-establishment of water repellency is not only due to a decrease in soil water content, but is likely to be associated with the energy input during heating and new input of hydrophobic substances (Doerr and Thomas 2000).…”

“…As to the effect of water content on water repellency, there exists a critical soil water content threshold above which the soil is wettable and below which the soil becomes water repellent (Doerr and Thomas 2000). De Jonge et al (1999) found that some soils are not water repellent at the very low water contents, but become water repellent as soil water content increases.…”

The effects of kaolinite additions and drying temperature on the persistence of soil water repellency, induced by humic acids from peat, were assessed in this study. It was found that additions of 5 and 10% kaolinite (referred to as the most effective material in combating the water repellency) did not result unambiguously in a decrease of the persistence of water repellency. In case of the higher humic acids contents, an increase of the persistence of water repellency was even noticed in comparison with the samples without kaolinite. Establishment (re-establishment) of water repellency was observed for the samples wetted to 30% after drying at temperatures of 30, 60°C (in both cases 36 of the 48 samples containing humic acids became water repellent) and after drying at 210°C (a few samples with the higher humic acids contents became slightly water repellent).
