“…The compliance between RI class and WDPT class pairs is visually presented in the weighted agreement chart in Fig. 5b (Friendly 2015; Papierowska et al, 2018). The red squares represent the likelihood of ranking in the same class for both variables and corresponds to exact agreement in classification (for example, for class 3 the likelihood is 33).…”

The extent (determined by the repellency indices RI and RIc) and persistence (determined by the water drop penetration time, WDPT) of soil water repellency (SWR) induced by pines were assessed in vastly different geographic regions. The actual SWR characteristics were estimated in situ in clay loam soil at Ciavolo, Italy (CiF), sandy soil at Culbin, United Kingdom (CuF), silty clay soil at Javea, Spain (JaF), and sandy soil at Sekule, Slovakia (SeF). For Culbin soil, the potential SWR characteristics were also determined after oven-drying at 60°C (CuD). For two of the three pine species considered, strong (Pinus pinaster at CiF) and severe (Pinus sylvestris at CuD and SeF) SWR conditions were observed. Pinus halepensis trees induced slight SWR at JaF site. RI and RIc increased in the order: JaF < CuF < CiF < CuD < SeF, reflecting nearly the same order of WDPT increase. A lognormal distribution fitted well to histograms of RIc data from CuF and JaF, whereas CiF, CuD and SeF had multimodal distributions. RI correlated closely with WDPT, which was used to develop a classification of RI that showed a robust statistical agreement with WDPT classification according to three different versions of Kappa coefficient.

“…PWI was calculated as the ratio of the intensity of the absorption bands of hydrophobic and hydrophilic functional groups in the organic matter of bulk soil (Leue, Gerke, & Ellerbrock, 2013). It was found from the comparison of above-mentioned methods that the SWR characteristics are somewhat, but not always, well related among each other (Doerr, 1998;King, 1981;Moody & Schlossberg, 2010;Papierowska et al, 2018;Vogelmann, Reichert, Prevedello, Awe, & Reinert, 2015).…”

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

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.

“…For sessile drop method measurements, the CAM 100 goniometer (manufactured by KSV Instruments, Finland) was used. Full description of the sessile drop method can be found in Papierowska et al (2018). The instrument was connected to a computer equipped with image recording software, drop shape analysis, and CA measurement tools.…”

“…This is the reason why we suggest for future leaf wettability research to measure and to present the change of contact angle with time. This approach was sometimes applied to other fields of research: e.g., in wood studies (Rodríguez-Valverde et al 2002), in pharmaceutics (Muster and Prestidge 2002), or soil studies (Leelamanie and Karube 2009;Papierowska et al 2018). The contact angle value decrease is caused by the change of the drop shape due to water spreading on the solid surface and to water absorption by the material but also to evaporation.…”

Key message Leaf CA measurement should take into account angle variation during measurement time. Leaf wettability of common deciduous forest plants is characterized by wetting contact angles ranging from 60° to 140° with a significant variation between species of the same family. Abstract Leaf wettability is an important phenomenon that has an influence on several processes such as the hydrological cycle, plant pathogen growth, or pollutant and pesticide absorption/deposition. The main objective of this research was to investigate the leaf wettability differences of 19 species (16 trees and 3 shrubs) of deciduous plants commonly occurring in Polish forests (temperate climate). The measurements were gathered as follows: 20 undamaged leaves were selected for each species and the wettability was determined by contact angle measurements with an optical goniometer CAM 100 using the sessile drop method. The contact angle was measured with 1-s intervals during 2 min from droplet deposition on adaxial and abaxial leaf surface. Laboratory analyses were completed during the summer of 2016 during full vegetation growth. A general CA decrease with time was observed on both leaf sides. The contact angle values ranged from 60° to 140° depending on species and leaf side. Differences between contact angle values at the beginning and the end of measurement reached 23.6° and engendered changes of wetting classes for some species. In many cases, no wettability class change was observed despite a CA lowering of 20°. The abaxial side was found to be the more repellent for 14 out of 19 species. Altogether, the leaves were classified from highly wettable to highly non-wettable, probably depending on the plant-survival strategy.
