Xin Huang, Chunwen Wei, Lin Qiu

Soil & Water Res., 2026, 21(3):133-146 | DOI: 10.17221/76/2026-SWR  

Under a changing environment, the characteristics of precipitation-runoff hydrological response relationship and the analysis of synchronous and asynchronous encounter frequency in large river basins play a crucial role in the water resources planning and management. Under the precipitation and runoff bivariate hydrological framework, segmented joint distribution models for precipitation and runoff of the Yellow River Basin (YRB) are constructed using the copula function. The wet and dry synchronous-asynchronous encounter frequency of precipitation and runoff is quantitatively analysed, and the driving factors underlying the variations in the precipitation-runoff...

Lukáš Puch, Bořivoj Šarapatka, Ivan Hadrián Tuf

Soil & Water Res., 2026, 21(3):191-202 | DOI: 10.17221/64/2026-SWR  

Soil-conserving strip cropping is increasingly promoted as an effective measure to reduce water erosion on sloping arable land, yet its consequences for biodiversity remain insufficiently understood. We evaluated the effects of strip cropping on ground beetle (Coleoptera: Carabidae) communities during two growing seasons (2023–2024) in South Moravia (Czech Republic), comparing long-term strip-cropped fields with conventionally managed monocultures. Ground beetles were sampled using pitfall traps, and differences in diversity, activity density, and species composition were analysed using univariate statistics, canonical correspondence analysis...

Bunthorn Thet, Hana Raková, Miroslav Fér, Aleš Klement, Antonín Nikodem, Abdul Majid, Radka Kodešová

Soil & Water Res., 2026, 21(3):159-168 | DOI: 10.17221/60/2026-SWR  

Although it is known that land cover affects soil water and thermal regimes, the influence of different land covers on soil water content and temperature in urban areas is rarely explored. Five soil surface treatments were selected in this study: bare soil, concrete paving, bark mulch, mown grass, and unmown grass. Soil water contents and temperatures were measured at five depths (5, 10, 25, 50, and 80 cm) over one year. The highest water contents were recorded under mulching. Under grass, water contents were lower and showed greater oscillations due to precipitation and evapotranspiration, while under mown grass, values were higher than under unmown...

Assessing the efficacy of soil conservation measures in reducing soil loss and surface runoff

Veronika Sobotková, Lukáš Buršík, Miroslav Dumbrovský, Michal Pochop, Miroslava Plevková

Soil & Water Res., 2026, 21(3):147-158 | DOI: 10.17221/57/2026-SWR  

Historically, agricultural land in the Czech Republic was highly diverse, and fields were commonly bordered by wooded areas. However, consolidation occurred, particularly during the collectivisation phase, resulting in fields of several hundred hectares. In such a uniform landscape, the soil is threatened by water erosion. In addition, there are other negative impacts on the environment, such as a decline in biodiversity. One of the ways to enhance landscape management is to implement soil conservation measures, e.g. strip cropping, contour farming, and agroforestry systems. This article deals with the impact of soil conservation measures on...

Discovering complex pesticide pollution in river water irrigated soil/groundwater systems: From targeted analyses to non-targeted screening and back

Alina Sadchenko, Petra Nováková, Aleš Klement, Miroslav Fér, Antonín Nikodem, Vít Kodeš, Radka Kodešová, Roman Grabic

Soil & Water Res., 2026, 21(3):179-190 | DOI: 10.17221/30/2026-SWR  

Pesticides and their transformation products are increasingly detected in agricultural soils and surface waters, raising concerns about their persistence, mobility, and ecological impacts. Irrigation with river water contaminated by agricultural runoff represents a significant but understudied pathway contributing to soil pollution. In this study, we investigated pesticide occurrence across soils, irrigation water, and groundwater in three intensively cultivated river basins. Soil samples from vegetable-producing fields exhibited complex contamination profiles, with 12–40 co-occurring compounds and total residues frequently exceeding levels reported...

Nana Afua Gyau Frimpong, Jacob Huerta, Ryan Webb

Soil & Water Res., 2026, 21(3):169-178 | DOI: 10.17221/26/2026-SWR  

Wildfires can greatly impact the hydraulic properties of soil. This study aims to utilise laboratory experiments to simulate burned soil conditions under a range of slope angles and rainfall intensities to address the research question: How does the presence of ash after the first rainfall event impact the hydraulic properties of burned soil in complex terrain? Sandy loam soils for this study were sourced from a mixed conifer forested area in the San Juan Mountains of southern Colorado, USA. Measurements of soil hydraulic properties in experimental microplots were taken (1) before burning, (2) after burning, and (3) 24 hours after a rainfall...

Radka Kodešová, Alina Sadchenko, Martin Kočárek, Miroslav Fér, Helena Švecová, Aleš Klement, Antonín Nikodem, Jindřich Zelinka, Marek Kučírek, Lenka Pavlů, Vít Kodeš, Roman Grabic

Soil & Water Res., 2026, 21(2):67-77 | DOI: 10.17221/35/2026-SWR  

Sorption of organic contaminants in soils and sediments is a crucial factor affecting their mobility in the vadose zone environment. Freundlich sorption isotherms were evaluated for six micropollutants identified in areas irrigated with river-water and sixteen soils. The highest Freundlich sorption coefficients, K_F, were obtained for 1,3-diphenylguanidine (11.6 ± 5.0 cm^3/nμg^1−1/n/g) followed by triethyl citrate (4.57 ± 4.91), 4-acetamidoantipyrine (1.43 ± 0.24), 6 : 2 fluorinated telomer sulfonate (1.18 ± 0.42), benzo(d)thiazole-2-sulfonic acid...

Spatial assessment of potential wind-driven soil loss using the Wind Erosion Equation

Josef Kučera, Martin Blecha, Jana Podhrázská, Jan Szturc, Hana Středová, Tomáš Středa, Petra Fukalová

Soil & Water Res., 2026, 21(2):78-88 | DOI: 10.17221/17/2026-SWR  

Wind erosion represents a locally significant soil degradation process in the Czech Republic, particularly in intensively farmed lowland regions. While areas susceptible to wind erosion have been previously identified, spatially explicit quantification of potential soil loss expressed in t/ha per year at the national scale has so far been lacking. This study presents a comprehensive assessment of potential wind-driven soil loss across the Czech Republic using the Wind Erosion Equation (WEQ). Special attention is given to the soil erodibility index (I), which was derived from extensive laboratory analyses of soil aggregates and evaluated using...

Use of agricultural wastes to reduce toxicity effect of tetracycline on soil nematode community

Shuang Zhong, Ting-Ting Song, Yan QIN, Yun-Hui Li, Xue-Yuan Bai

Soil & Water Res., 2026, 21(2):98-106 | DOI: 10.17221/148/2025-SWR  

In order to remove soil tetracycline residue and identify the effect of tetracycline on soil nematode community, agricultural waste returning was applied in a maize monocropping field, northeast China. The results showed that plant parasites were the dominant genera in high concentration of soil tetracycline; however, bacterivores were the dominant genera in all organic matter amendments. Maturity index, structure index and enrichment index showed the highest values in biochar and compost mixed amendments and these treatments had the highest tetracycline removal rate and the highest concentration of macro-aggregates, total organic C and available...

Jan Skála, Daniel Žížala, Robert Minařík

Soil & Water Res., 2026, 21(2):89-97 | DOI: 10.17221/128/2025-SWR  

Machine learning makes geochemical mapping highly adaptable, as its data-driven nature allows predictions to evolve with new information. In this study, topsoil nickel (Ni) data were compiled from various sources, each with different sampling times and analytical methods. To effectively use such imbalanced data into spatial modelling, it was necessary to test how the data uncertainty propagated through the final maps. A comprehensive benchmark of the quantile random forest algorithm was conducted to identify conditions under which the model performs optimally. Predictive maps of topsoil Ni at a 20-metre resolution were subsequently generated and compared...

Ni Made Trigunasih, Moh Saifulloh, Ida Bagus Putu Bhayunagiri, Zulkarnain Zulkarnain

Soil & Water Res., 2026, 21(2):107-120 | DOI: 10.17221/96/2025-SWR  

Reliable indicators of early soil biological change remain limited in tropical agroecosystems, where soil organic carbon (SOC) stocks may respond more slowly than microbial processes. We evaluated whether seasonal vegetation dynamics derived from Sentinel-2 fractional vegetation cover (FVC) are associated with spatial variation in SOC stock and microbial indicators in Jembrana, Bali, Indonesia. We mapped seasonal FVC from 2019 to 2024 and derived site-level metrics of mean cover and temporal variability (standard deviation, anomaly, coefficient of variation, and a temporal stability index). In July 2023, we sampled topsoil (0–30 cm) at 12...

Lenka Pavlů, Marek Kučírek, Václav Tejnecký, Ondřej Drábek, Petra Vokurková, Luboš Borůvka, Martin Valtera, Věra Fadrhonsová, Radek Novotný

Soil & Water Res., 2026, 21(1):43-51 | DOI: 10.17221/119/2025-SWR  

This research focuses on the effects of large-scale clearcuts resulting from salvage logging after spruce (Picea abies) forest dieback caused by an extreme bark beetle infestation, and on the effect of logging residues management (chopping vs. clearing) on the distribution of potentially toxic elements (PTEs) in soil. Pseudo-total contents of Cd, Cr, Cu, Ni, Pb and Zn were determined in soil samples collected separately from the organic (F+H) and mineral (0–10, 10–20, and 20–30 cm depths) soil layers. The distribution of elements was influenced mainly by sampling locality and position in the soil profile. In general, the contents...

Haowei Xu, Yuhong Tong, Li Zhou, Huizhen Li

Soil & Water Res., 2026, 21(1):34-42 | DOI: 10.17221/91/2025-SWR  

Alpine meadows, one of the most widespread and important vegetation types on the Qinghai-Tibet Plateau, are facing severe degradation. This study examines how degradation affects soil medium and trace elements in the eastern Qinghai-Tibet Plateau, along with their relationships with plant traits and soil properties. Results indicate that alpine meadow degradation significantly reduces vegetation coverage, height, biomass, soil water content (SWC), and the levels of soil organic carbon (SOC), nitrogen (N), and phosphorus (P), while increasing soil bulk density (BD), pH, and potassium (K) content. Soil Ca, Zn, and Mo decrease with degradation, whereas...

Xu Fan, Wei Hu, Zhongzheng Ren, Yuan Chen, Qingsong Shen, Xingyi Zhang

Soil & Water Res., 2026, 21(1):9-19 | DOI: 10.17221/39/2025-SWR  

Rainfall is a major contributor to water erosion of sloping cropland in Northeast China. Identifying how rainfall and slope gradient (S) influence runoff depth (RD) and sediment yield (SY) is crucial for preventing water erosion. Field measurements from runoff plots were collected from 2023 to 2024, and K-means clustering was applied to clarify the rainfall patterns. Response of RD and SY to the rainfall pattern and S were analysed. Key factors impacting RD and SY were explored. The results showed that three rainfall patterns were identified for 34 erosive rainfall events: A (41.2%, medium...

Aleš Vaněk, Maria Vaňková, Vojtěch Ettler, Martin Mihaljevič, Bohdan Kříbek, Petra Vokurková, Tereza Zádorová, Vít Penížek, Ondra Sracek, Benjamin Mapani

Soil & Water Res., 2026, 21(1):1-8 | DOI: 10.17221/143/2025-SWR  

In this study, we present a detailed geochemical characterisation and stable isotope systematics of silver (Ag) in a mining waste facility at the Namib Lead & Zinc mine in Namibia (Africa). We examined a series of flotation tailings and ore minerals to address two principal questions: (1) the distribution, chemical form and leachability of Ag, and (2) the local Ag isotopic signature(s) and its variability in relation to Ag speciation in the solid phase, as well as the fate of stable Ag isotopes. Our findings reveal a significant correlation between Ag and Pb concentrations, indicating that galena is the primary Ag carrier. Most importantly, all...

Economic evaluation of conservation grassland as a measure to control soil erosion in the Czech Republic

Ivo Horák, Marek Litzman, Petr Marada, Lubor Lacina, Miroslav Dumbrovský, Jan Vavřina, Michal Pochop

Soil & Water Res., 2025, 20(4):274-284 | DOI: 10.17221/33/2025-SWR  

Conservation grassland significantly reduces soil erosion risk in agricultural landscapes, as shown by a nationwide analysis of over 1.9 million Farmer’s blocks (DPBs) records from the Czech Republic (2016–2022). A logit regression model revealed that grassland establishment lowers the likelihood of erosion events by about 64%, with erosion risk strongly influenced by altitude, land use, and management practices. Spatial mapping and soil suitability classification identified nearly 240 00 hectares – mainly along 33 000 concentrated runoff pathways – as suitable for targeted grassland conversion. Despite its soil-protective function,...

Michal Dohnal, Jana Votrubová, Rebeka Mazúchová, Miroslav Tesař

Soil & Water Res., 2025, 20(4):265-273 | DOI: 10.17221/24/2025-SWR  

Ground heat flux (G) is often an overlooked component of the surface energy balance, and its accurate determination remains challenging. In the present study, the accuracy of various G estimation methods is examined using long-term measurements from the Central European mountain meadow. The impact of different G approximation on calculated evapotranspiration by the Penman-Monteith method (ET) is analysed. Soil heat flux measurements and surface temperature data were used to determine G, while net radiation was used to approximate G. Neglecting G led to an overestimation of ET in the daily timestep....

Determination of soil loss on agricultural land based on field measurements in the Czech Republic

Jiří Kapička, Věra Kolbabová, Miroslav Bauer, Tomáš Dostál, Petr Kavka, Josef Krása, Alla Achasova

Soil & Water Res., 2025, 20(4):253-264 | DOI: 10.17221/22/2025-SWR  

The current erosion protection set up in the Czech Republic (CZ) is based on the long-term soil loss due to water erosion using the Universal Soil Loss Equation (USLE). The range of recommended values of tolerable soil loss by water varies among different authors and approaches, depending on the specific area and its parameters. It is, therefore, important to ask the following questions. What is the real range of soil loss by water erosion in CZ. To determine the range of soil loss, a model extrapolation was carried out. The model extrapolation was based on the results from two main experimental measurements. Both from the evaluated volume soil loss...

Possibilities of agricultural soils evaluation in the Czech Republic

Věra Ürge, Pavel Formánek, Jan Vopravil

Soil & Water Res., 2025, 20(4):243-252 | DOI: 10.17221/66/2025-SWR  

In this study, the evaluation of soil quality was realised using the Analytic Hierarchy Process, and the obtained values were integrated with Evaluated Soil Ecological Units (BPEJs). Different maps of the Czech Republic were elaborated with BPEJs classified into five soil protection classes based on the obtained model values (with or without the values for production potential), the ratio of 80% (production potential values) to 20% (model values) or 60% (production potential values) to 40% (model values) and 40% (production potential values) to 60% (model values). The evaluation of BPEJs based on the mentioned criteria showed differences in their classification...

Rainfall induced changes in soil moisture: A comparative study of conventional and strip tillage

Vojtěch Štros, David Kincl, David Kabelka, Jan Vopravil

Soil & Water Res., 2025, 20(4):234-242 | DOI: 10.17221/56/2025-SWR  

Strip tillage is a very popular form of conservation tillage that is used in places with a higher risk of soil erosion. It is commonly accepted that strip tillage reduces the effects of water erosion; however, the exact way this effect is produced is very hard to quantify. This study focuses on the way strip tillage influences soil moisture and the way it changes with different intensities of rainfall, in comparison with conventional tillage. This study was conducted near Petrovice, Středočeský kraj, Czechia, over the course of four years (2021–2024). The conditions of all four test sites were comparable, both in terms of slope and soil type...

Alternative solution for determining the irrigation water quantity: ET_Gauge

Ismail Tas, Fatih Cem Kuzucu

Soil & Water Res., 2025, 20(4):219-233 | DOI: 10.17221/25/2025-SWR  

Measuring the reference evapotranspiration (ET₀) is difficult and costly. Some regions can have variable microclimates and these can often be quite far from climate stations. Therefore, it is optimal to use local measurements rather than a regionally calculated ET₀. In this respect, one piece of equipment that provides cheap and reliable measurement results is ET_Gauge equipment. In this study, ET₀ values measured with ET_Gauge equipment were compared with daily and monthly ET₀ values calculated by five different commonly used empirical methods (Thornthwaite_Adj, Blaney-Criddle,...

Effects of variable rate fertiliser application on selected macronutrients leaching from the ploughed layer

Jan Vopravil, Pavel Formánek, Ondřej Holubík, Pavel Svoboda, Tomáš Khel

Soil & Water Res., 2025, 20(3):206-217 | DOI: 10.17221/28/2025-SWR  

In this study, the effects of standard fertilisation versus variable fertilisation with mineral and organomineral fertilisers on N, P, K, Ca and Mg leaching from the ploughed layer and yields of winter wheat and spring wheat (Triticum aestivum L.) and spring barley (Hordeum vulgare L.) were studied. The losses of calcium were the highest, and phosphorus from phosphates was the lowest of all studied nutrients when simulated rainfall and lysimeters were used after the crops were harvested. The use of variable rate fertilisation reduced nitrates leaching in all the studied plots. Nevertheless, leaching of calcium, which is present in higher...

Comparison of the cadmium and lead removal from three soils by electrokinetic remediation

Mei Zhang, Chengdong Duan, Xinfu Wang

Soil & Water Res., 2025, 20(3):195-205 | DOI: 10.17221/140/2024-SWR  

This study investigated, for the first time, the efficacy of citric acid (CA) and ethylenediaminetetraacetic acid (EDTA) as electrolytes in electrokinetic remediation (EKR) for removing lead (Pb) and cadmium (Cd) from three distinct soils (Anthrosols soil, AT; Acrisols soil, AC; and Chernozems soil, CH). Under a voltage gradient of 2 V/cm and a remediation duration of 4 days, EDTA proved most effective for Anthrosols, achieving removal rates of 17.8% for Cd and 12.8% for Pb-lower than those observed for Acrisols and Chernozems, likely due to AT’s high pH background. These results suggest that combining EKR with other remediation techniques could...

Weikang Chen, Ling Xiong, Qiqian Wu, Petr Heděnec, Yan Peng, Zemin Zhao, Chaoxiang Yuan, Ji Yuan, Xiangyin Ni, Fuzhong Wu, Kai Yue

Soil & Water Res., 2025, 20(3):164-177 | DOI: 10.17221/7/2025-SWR  

Forest headwater streams serve as critical interfaces between terrestrial forests and downstream aquatic ecosystems, playing essential roles in the storage and movement of carbon (C) and nutrients. However, despite their importance, our understanding of the dynamics of plant litter calcium (Ca) and magnesium (Mg) stocks within these streams remains limited. In this study, we conducted a quantitative analysis of the spatiotemporal dynamics of plant litter Ca and Mg concentrations and stocks in a subtropical forest headwater stream from March 2021 to February 2022. We found that: (1) the average concentrations of litter Ca and Mg were 9.9 and 0.7 mg/g,...
