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 simulation. A total of 15 experimental microplots with ash applied were run through rainfall simulations at slope angles ranging from 10° to 30°. Results found ash eroded had no significant relation to slope angle, but there was a significant reduction in field saturated hydraulic conductivity of samples with ash after rainfall simulations. To build on the findings presented here, future research should conduct field-based studies across various ecosystems and soil types to observe post-fire soil changes over time.

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 for European arable soils. Several pesticides, including pendimethalin, mandipropamid, and azoxystrobin, were found at notably high concentrations, with some soils surpassing 5 000 µg/kg. Comparison of detection frequencies across matrices revealed diverse transport and retention behaviour: while certain legacy compounds (e.g., atrazine metabolites) were ubiquitous in both surface and groundwater, others showed strong soil accumulation with limited mobility. Irrigation water was identified as a non-negligible contamination source, particularly for persistent and mobile substances, although direct field applications remained the dominant contributor to peak soil concentrations. By integrating targeted and non-target screening, this study provides the most comprehensive assessment to date of pesticide burdens in riverirrigated agricultural soils and highlights the need for improved monitoring strategies in systems where soil and water pollution are tightly interconnected.

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 erosion and runoff conditions. Forty-eight variants were proposed. In some variants broad-base terraces were considered. It was observed that the design of the measures resulted in a significant reduction in both soil loss and surface runoff. Among the evaluated measures, strip cropping proved to be highly effective in reducing sediment transport. The combination of strip cropping (winter barley and winter rapeseed), an agroforestry system featuring 6 m wide grass belts with a slight contour deviation, and two broad-base terraces mitigated erosion by approximately 84%. Nevertheless, this management practice introduces a significant spatial footprint of grass belts and unproductive land, around 27%.

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 grass. Similarly, near-surface bare soil water contents also fluctuated. The water content under the concrete remained almost constant. While the soil under concrete paving, bare surfaces and even mown grass warmed up considerably during the day because of the absorption of solar radiation and cooled down at night due to the emission of stored heat, the soil under bark mulch and unmown grass cover showed smaller temperature fluctuations, mainly due to the low thermal conductivity of the surface layer and surface shading. The effects revealed throughout the entire soil profiles decreased with depth.

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 (CCA), and generalised additive models (GAMs). Strip cropping consistently supported higher ground beetle diversity than conventional management, while significantly higher activity density became evident after longer implementation. Furthermore, this management enhanced diversity at upper erosional positions, indicating reduced environmental stress. Species-specific analyses showed that several xerophilous and conservation-relevant species were associated with habitats promoted by strip cropping. Our findings demonstrate that the ecological benefits of strip cropping extend beyond erosion control. By increasing within-field habitat heterogeneity and improving conditions for ground beetle assemblages, strip cropping simultaneously supports biodiversity and soil conservation. These results highlight its potential as a multifunctional management practice capable of reconciling agricultural production with biodiversity conservation in erosion-prone landscapes.

China Title: Segmented characteristics of precipitation-runoff response structure relationship in the Yellow River Basin over the past 20 years Abstract: 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 relationship are discussed. The results show that from 2005 to 2024, precipitation and runoff for Lanzhou (upper reaches), Longmen (middle reaches), and Lijin (lower reaches) hydrological station of the YRB exhibited an upward trend. The wet and dry synchronous frequencies between precipitation and runoff at these three stations were 55.24%, 58.26% and 57.67%, respectively, all higher than the asynchronous frequencies, indicating that the whole basin is likely to experience synchronous wet or dry hydrological regimes. Furthermore, in the YRB, the explanatory power of precipitation on natural runoff gradually decreases from upstream to downstream. Land use and land cover change induced by grain-for-green projects and urbanisation are likely the main causes of natural runoff variation and the alteration of the hydrological response mechanism in the YRB.
