Summary: This paper investigates the impact of petroleum hydrocarbon contamination on soil water sorptivity and hydrophobicity. It is found that contamination with petroleum hydrocarbons reduces soil water sorptivity and increases soil water repellency. The results suggest that the interrelationship between contamination level, water sorptivity, soil water repellency, and soil moisture is crucial in predicting the environmental effects of petroleum hydrocarbon contamination.

Summary: Soil water repellency is a dynamic property of soil that depends on factors such as climate warming and increased frequency of droughts. Studies have found that on sandy soil, pine sites exhibit more persistent and severe water repellency compared to regions with a warmer climate, potentially playing a key role in identifying soil drying risks.

Summary: Water-repellent soils experience water flow impedance and progressive increase of infiltration rate during wetting process, which current infiltration models cannot describe. The modified BEST-WR method provides a new approach for hydraulic characterization of soils at any stage of water-repellency, introducing a new index to assess soil water repellency.

Summary: Rainfall-induced slope failures are mainly caused by infiltrated rainwater reducing soil shear strength. This study proposes a method for estimating the hydraulic conductivity function (HCF) of unsaturated soil during the wetting process based on the drying soil-water characteristic curve (SWCC). The estimation considers ink-bottle and rain-drop effects on the hysteresis of SWCC and was verified using experimental data from published literature.

Summary: The study investigated the changes in soil hydrodynamic properties after soil tillage through rainfall simulation trials in central Italy. The experiments aimed to build a representative database of natural situations. The collected data were used to determine the saturated soil hydraulic conductivity, sorptivity, and flow-weighted mean pore size. The results showed a reduction in both sorptivity and hydraulic conductivity due to wetting and drying cycles, with the decrease in hydraulic conductivity being related to the energy dissipated at the soil surface.

Summary: Water redistribution has a profound impact on the function of dryland ecosystems. Biological soil crusts (BSCs or biocrusts), which cover a large portion of arid land soil surface, have conflicting effects on water redistribution at a regional scale. This study clarified the effects of different biocrusts on soil hydraulic properties in the Tengger Desert. The results showed that biocrusts significantly altered soil hydraulic properties, including water holding capacity, soil hydrophobicity, water sorptivity, and unsaturated hydraulic conductivity. Understanding the role of biocrusts in hydraulic properties can help improve our understanding of soil water distribution, movement, and retention in the area.

Summary: This study investigates the determination of soil saturated hydraulic conductivity (K-s) and soil sorptivity (S) using three different methodologies for eight different soils. The results suggest that the relative errors in predicting S were generally smaller than those of K-s. The nonlinear optimization procedure using the Valiantzas equation provided the best prediction of S and K-s, while the two-term approximate expansion of Haverkamp had the highest relative errors for both parameters. The various forms of the Haverkamp equation and the Latorre method showed good predictions of S and K-s for fine-textured soils.

Summary: This study examined how slope position interacts with plant mucilage to influence soil physical stability. Changes in soil physical stability due to plant mucilage have seldom been considered with respect to slope position. Interactions between mucilage and soil particles resulted in greater physical stability on the midslope compared to the footslope.

Summary: The study found that deep non-inversion and minimum tillage practices led to higher soil organic carbon levels compared to conventional ploughing in rotational systems, while conventional ploughing had higher soil organic carbon levels than plough compaction, minimum tillage, and zero tillage in a monoculture system in Scotland. Bulk density was also higher in the soil surface of conventional plough compared to minimum tillage after harvest. Overall, the study suggests that there is limited benefit in using shallow minimum tillage and zero tillage practices in the UK to increase soil carbon storage.

Summary: The study uses four artificial neural networks to analyze and simulate the spatial patterns of crop yield for seven crop species in Guizhou Province, China, revealing that most high-yield regions are located in the central-north area. Factors such as temperature, radiation, soil moisture, fertilization of N and P have the largest contribution to crop yield spatial distribution. The research suggests the potential application of neural networks in identifying environmental controls on crop yield and modeling spatial patterns of crop yield for sustainable development and crop production goals.

Summary: Global nitrogen deposition to forests can alleviate ecosystem N limitation, but better quantification of nitrogen fluxes is needed to predict the consequences. Studies in central Europe reveal that dissolved N losses in streams are related to nutrient stoichiometry, while soil N storage is linked to iron and aluminium content. Gaseous N losses are influenced by forest floor N:P ratio and dissolved N losses, and a relationship between gaseous and dissolved N losses can explain N loss rates in tropical and subtropical catchments, driven by nitrate abundance. Extrapolating globally, current gaseous N losses from forests are estimated to be 8.9 Tg N yr(-1), representing 39% of current N deposition to forests.

Summary: This study in the Czech Republic focused on the changes in element fluxes in semi-natural forest ecosystems and their relationship with anthropogenic acidification recovery, finding reductions in sulphur and nitrogen deposition. Changes in stream chemistry were influenced by nitrogen and sulphur deposition, with soils acting as a net source of sulphur in most catchments. Stream nitrate concentration decreased more than nitrogen deposition, and was closely related to the stream dissolved nitrogen to phosphorus ratio.

Summary: The study compared several interception modelling approaches and found that a simple method of subtracting a constant value from each rainfall event was the most efficient. While there was a slight increase in RMSE for discharge and groundwater level, soil moisture did not show significant differences. The overestimation of transpiration rate was around 3-5% on average, highlighting the efficiency of simple interception models in hydrological modelling tasks focused on specific water fluxes in forested catchments.

Summary: There is great potential to utilize plant traits at the root-soil interface, such as rhizodeposition and root hairs, to improve soil structure, enhance carbon storage and resource utilization, enhance resistance to climate stresses, and promote a healthy microbiome. These traits are present in modern crop varieties, but there is room for further improvement as they vary significantly across genotypes and respond to environmental conditions. Future research should focus on studying the impacts of selecting these traits on both plants and soils, from model plants to commercial genotypes, and determining if the effects observed in greenhouse studies can be replicated in the field.

Summary: A better understanding of factors controlling the distribution of soil organic matter (SOM) in different stabilized pools in soils during ecosystem development is essential for efficient soil management as a carbon sink and to aid in mitigating global warming. This study found that bio-physicochemical soil properties are the best predictors for both C and N stocks, while plant litter production and succession age have minor importance. The relevance of biotic and abiotic factors shifts from free particulate organic matter (fPOM) and various aggregate fractions to mineral-associated organic matter (MAOM), indicating that sites dominated by MAOM may have slower responses to management interventions. Secondary successions were associated with higher C and N stocks in aggregate fractions compared to primary successions, suggesting better conditions for soil structure formation in the former.

Summary: Sustainable farming systems provide food for humans while balancing nutrient management. The inclusion or exclusion of livestock has significant implications for nutrient management. Plant-based diets are becoming more popular due to perceived environmental benefits. This study found that combining synthetic fertilizers with organic amendments significantly increased production while balancing nutrient management. Legume-supported rotations without livestock produced more protein, starch, and sugar. Nutrient balances and use efficiencies were more sensitive to management changes than purely food production.

Summary: Temporary storage areas (TSAs) are nature-based solutions that can store and attenuate surface runoff, providing additional storage during flood events in a catchment. The implementation of small-scale TSAs in headwater catchments is gaining momentum, but further evidence is needed on their effectiveness during flood events. This review examines the role of small-scale TSAs in flood risk management and explores their potential benefits in integrated catchment management. Factors influencing TSA functioning and effectiveness are discussed, along with considerations for future design and management.
