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: This study investigated the changes in soil bulk density (BD) and saturated hydraulic conductivity (Ks) along a 500 km transect on the Chinese Loess Plateau, finding that variations in BD and Ks were significantly influenced by land-use types, seasonal changes, sampling time, and soil water condition. Understanding these temporal variations and their dominant factors will help to optimize hydrological models more accurately at a regional scale.

Summary: Plastic pollution has adverse effects on soil health, but assessing the impact and trends of plastic-induced changes in soil properties is complicated due to the heterogeneity of plastic and soil characteristics. This study quantified the effects of different plastic characteristics on soil physical properties and found that different types, shapes, and concentrations of plastics significantly modified the analyzed soil properties.

Summary: This study compared the root performance of different rotation crops and their effects on soil hydraulic properties, revealing that the productivity of clayey Utisol in southern China is limited by poor soil hydraulic properties. All crops contributed to improving soil hydraulic properties, with fine roots playing a key role in forming aeration and active capillary pores.

Summary: Loess content has significant effects on soil hydrological properties in coarse-textured soils, especially in subsoils with low SOC contents. However, for coarse-textured topsoils, SOC content plays a dominant role in affecting soil hydrological properties.

Summary: Biochar is a porous carbonaceous material that can improve the physical properties of soils. However, there is uncertainty about the effects of biochar application on soils, limiting its acceptance. Biochar affects the physical functions of soil, and factors such as feedstock, pyrolysis conditions, particle size, and rate of amendments influence its effectiveness. The chemical properties and interactions between biochar and soil interface also play a significant role in its impact.

Summary: This study aimed to assess the suitability of image analysis for estimating gas and liquid transport in resin-impregnated soil blocks. By measuring various soil properties, it was found that morphometric parameters of soil structure derived from image analysis were related to the saturated hydraulic conductivity and air permeability of the soil. The total volume of soil pores was identified as the key factor influencing soil infiltration, with other parameters such as macroporosity and pore path length also playing important roles in characterizing the soil pore system.

Summary: Global land use change has led to an increase in pasture and cropland at the expense of woodlands. The impact of this change on soil hydraulic function and its feedback to the hydrological cycle is still unclear. The study found that predictive methods for soil hydraulic conductivity provide reasonable results for cropland, but underestimate this property in grassland and woodland. The difference in soil hydraulic conductivity can be attributed to variations in bulk density and compaction caused by heavy grazing.

Summary: This study aims to provide practical guidance for woodchip selection from a hydraulic design perspective. Relationships between particle size, porosity, bulk density, and saturated hydraulic conductivity were established for 20 commonly available woodchip types. The study found that woodchip types with a diameter in the range of 13.5-16.8 mm are suitable for standardized denitrifying bioreactor designs.

Summary: This study develops a simple water retention model for dual-porosity soils that considers the self-similar characteristics of the pore size distribution (PSD) between macropore and micropore regions. The model simulates the macropore PSD using the differential VG model, which is then shifted and scaled to capture the micropore PSD. The results show that the proposed model can accurately predict the water retention behavior and hydraulic conductivity of dual-porosity soils.
