“…Despite simplifications in reflecting field conditions (e.g., the lack of vegetation), the obtained results indicate the direction of changes in the rainfall-runoff relationship when the phenomenon of water repellency occurs. Water repellency was characterized by seasonality, which was also observed by Buczko et al [17,18], Leighton-Boyce et al [26], and Hewelke et al [11,15]. On the analyzed site, the soil was wettable in the period of early spring, whereas the phenomenon of water repellency occurred after a longer period without rainfall.…”

“…The reasons behind water repellency are being identified to an increasingly wider extent and are related to the occurrence of organic carbon, especially humic and fulvic acids, as well as waxes and lipids of different origins [2][3][4][5][6]. Water repellency also occurs following forest fires and the burning of grasses [7][8][9][10][11] as well as soil contamination with crude oil derivatives [12][13][14][15]. Water repellency is of a seasonal nature and is strictly connected with soil moisture content [16][17][18][19][20][21].…”

Soil water repellency can significantly degrade its agricultural utility and bring aboutnegative environmental consequences (i.e., reduced infiltration capacity, enhanced overland flow,increased erosion rates, and water infiltration occurred in irregular patterns). The presented studyaimed to establish whether excluding albic Podzols from agricultural production and theirspontaneous inhabitation by a pine tree stand affected their hydrophysical properties. Studies withthe application of the water drop penetration time (WDPT) test showed that a change in the landuse increased the potential water repellency of the surface layer (horizon A) and caused itschangeover from strongly repellent class (Class 2) to extremely repellent (Class 5). The relationshipbetween soil moisture content and wettability made it possible to determine the critical soil moisturecontent (CSMC) for the occurrence of the phenomenon of water repellency. It was confirmed thatthe CSMC value increased along with a change in use. For the site under arable use, it was 9–10vol.%, whereas for the site formerly under arable use and currently covered predominantly by apine tree stand, a value in the range of 14–16 vol.% was reached. A laboratory experiment on surfacerunoff of the soil formerly under arable use showed that over half of the rainfall may be transformedinto surface runoff as a result of occurring water repellency. This means that exceeding the criticalsoil moisture content makes the recharge of soil retention difficult and may significantly influencethe water balance of soil, as well as increasing its susceptibility to drought.

“…However, this streak was broken by the years 2015 and 2016, both of which were characterized by mild and snowless winters and a relatively unfavourable distribution of rainfall times. Additional details of the meteorological conditions in 2015/2016 and the study area had been published in an earlier work [53]. These two years did not reverse the general tendency, but the levels of groundwater in 2015/2016 were the lowest in the history of measurements after 2003.…”

Progressing climate change increases the frequency of droughts and the risk of the occurrence of forest fires with an increasing range and a dramatic course. The availability of water and its movement within an ecosystem is a fundamental control of biological activity and physical properties, influencing many climatic processes, whereas soil water repellency (SWR) is a key phenomenon affecting water infiltration into the soil system. Focusing on wide-spectrum effects of fire on the soil system, the research was conducted on a pine stand (Peucedano-Pinetum W. Mat. (1962) 1973) in Kampinos National Park located in central Poland, affected by severe and weak fires, as well as control plots. The main aim of the study was to examine the regeneration of the ecosystem 28 months after the occurrence of a fire. The effect of SWR and soil moisture content, total organic carbon, nitrogen and pH, and gain an understanding of the environmental conditions and processes that shaped the evolution of the species structure of soil microorganism communities (fungal vs. bacterial) have been examined. The Water Drop Penetration Time (WDPT) test was used to assess spatial variability of SWR in 28 plots. Soil bacterial and fungal communities were analysed by Illumina’MISeq using 16S rRNA and Internal Transcribed Spacers 1 (ITS1) regions in six selected plots. After a relatively wet summer, elevated hydrophobicity occurred in areas affected by a weak fire as much as 20 cm into the soil depth. The severe fire and subsequent increase in the richness of the succession of non-forest species contributed to the elimination of hydrophobicity. SWR was more closely linked to the structure and diversity of soil microbial communities than soil physicochemical properties that took place in response to the fire. A statistically significant relationship between the relative occurrence of microorganisms (≥ 1.0% in at least one of the samples) and SWR was established for the following fungi and bacteria species: Archaeorhizomyces sp., Leotiomycetes sp., Byssonectria fusispora, Russula vesca, Geminibasidium sp., family Isosphaeraceae and Cyanobacteria (class 4C0d-2, order MLE1-12). Insight into the functional roles of the individual identified microbial taxa that may be responsible for the occurrence of hydrophobicity was also presented.

“…The occurrence and development of preferential flow in the soil are closely related to water, transport, and the accumulation of nutrients in the soil [57,58]. In this study, we used SPSS to calculate the soil nutrients and characteristic parameters of preferential flow to study the correlation between preferential flow and the accumulation of soil nutrients ( Table 7).…”

Preferential flow is an important water infiltration phenomenon in karst regions. The response of preferential flow to vegetation restoration requires urgent investigation due to the special soil structure of karst regions. In order to study the effect of vegetation restoration on water movement in karst regions, four kinds of ponded water infiltration experiments were carried out in Pinus Yunnanensis plantation forestland, secondary forestland, and natural grassland. A brilliant blue dyeing experiment was conducted to visualize the distribution of water infiltration in soil (a total of 150 stained images from vertical soil slices). Results showed that the average depth of matrix flow in natural grassland was approximately six times those in plantation and secondary forestlands. An increase in matrix flow will have a negative effect on the development of preferential flow. Water transported in preferential flow paths affects the distribution of nutrients and organic matter in the soil. However, preferential flow in grassland can promote the accumulation of available nutrients, and preferential flow in plantations can inhibit the loss of organic matter. Preferential flow in grasslands and forest plantations is less than that in native forests soils. Preferential flow increases the percolation of water in soils. The effect is that preferential flow can obstructs water uptake by the roots under low rainfall conditions, and decreases surface runoff before soil saturation under high rainfall conditions. In the process of nutrient element migration, preferential flow has a good contribution, which is conducive to the migration and accumulation of elements required for surface vegetation growth. The contribution of preferential flow needs to be considered in studies on vegetation restoration planning and land degradation.
