Summary: Soil erosion by water is a global ecological issue that leads to land degradation. This study focuses on splash erosion caused by raindrop impact and its relation to soil aggregate characteristics in humid tropical regions. The results show that soil aggregate properties such as organic carbon, water-stable aggregate index, and mean weight diameter decrease after land-use change from tropical rainforest to rubber plantation, leading to higher splash erosion rates in the latter.

Summary: Soils in alpine ecosystems are significant carbon sinks, with soil aggregates and their pore structure playing a crucial role in carbon sequestration. This study examined the soil pore structure, carbon content, and their relationships in three typical alpine ecosystems in the Qinghai-Tibet Plateau. The results revealed the dominance of small macroaggregates and microspores in the soil aggregates, as well as the correlation between carbon content and pore characteristics. Additionally, the study highlighted the impact of soil water content and particle compositions on soil organic carbon in different alpine ecosystems.

Summary: Gas flow in shale nanopores is crucial for shale gas exploitation. Organic matter, with its gas storage ability, plays an important role in gas shale reservoirs. Existing permeability models mainly focus on specific factors such as pore diameter or mathematical distribution, rather than pore size distribution. Our research shows that the Kapp curves of organic matter exhibit transition steps from transitional flow to slip flow, with porosity, dominant pore diameter, and frequency being the main factors affecting organic matter's Kapp.

Summary: The addition of exogenous organic matter can stimulate microbial activity and shape soil structure, particularly at higher doses. The impact of the application dose of exogenous organic matter on its own mineralization and that of native soil organic carbon by mediating soil pore network structure is not well known.

Summary: The study examined the impact of soil texture and degree of compactness on total porosity and distribution of macro-, meso- and micropores. It found that total porosity and macroporosity are dependent on compactness and silt plus clay content, while meso- and micropores are mainly affected by particle size distribution. The findings suggest that increasing compactness may reduce total porosity and macroporosity, with meso- and micropores being more sensitive to changes in particle size distribution.

Summary: The study on the effects of rice husk biochar and cattle manure compost on a sandy loam rural soil in southern Taiwan showed that both amendments promoted soil aggregation and enriched soil organic carbon. The addition of compost further enhanced organic carbon enrichment in microaggregates and mesoaggregates, suggesting their potential role in enhancing carbon sequestration.

Summary: This study investigated the effects of organic amendment on soil structure and hydraulic properties. The results showed that organic amendment improved soil aggregate stability, saturated hydraulic conductivity, and gas diffusivity, while also enhancing soil aeration. Additionally, the application rate of the amendment had an influence on soil structure and properties.

Summary: The study quantified the soil particle size distribution (PSD) of sodic soils using the multifractal method, revealing an increased heterogeneity in PSD after reclamation and a decrease in major particle size. The findings suggest that reclamation treatments can improve soil physical and chemical properties, enhancing soil quality.

Summary: The dynamometer method is used to determine particle size distribution and can be applied in soil sample research. This study investigates the effect of removing organic matter using hydrogen peroxide on particle size distribution results and identifies differences in soil samples after organic matter removal.

Summary: Organic matter amendment is used to improve soil quality in agricultural and urban settings, including supporting local food production and reclaiming disturbed soils in urban regions. Compost and biochar had the greatest improvement on soil organic matter content, while biosolids had greater nutrient benefits. The application of organic matter amendments also improved chemical and physical soil quality parameters. However, there are still gaps in the literature regarding the effects of amendments in urban gardens, soil depth greater than 30 cm, and the persistence of soil organic matter.

Summary: The study demonstrated a close association between jarosite and organic matter in areas with high jarosite concentration, while the pore space near the root was almost completely filled by jarosite, encapsulating organic matter. This poor accessibility of organic matter is likely to significantly slow down the remediation processes of sulfuric soils after re-submergence.

Summary: This study investigates the changes in the pore structure and strength of loess by mixing it with organic matter. The results show that the content of organic matter and water are important factors affecting the resistivity of organic soil. The findings provide valuable references for vegetation restoration, land use, and conservation strategies in ecosystems.

Summary: Microplastics in soils, introduced through composting household waste, have been examined for their distribution and degradation in agricultural soil samples. The microplastics, mainly consisting of polyethylene, polypropylene, polystyrene, and polyvinylchloride, are present in the cultivated depth of the soil but have not migrated deeper. Advanced degradation, possibly due to composting, was observed.

Summary: This study aims to elucidate the initial aggregate formation in calcareous loess, showing that organic matter induces the formation of large macroaggregates, while microaggregates do not accumulate soil organic carbon. The findings suggest that soil aggregate formation on young calcareous soils involves both fresh soil organic matter contributing to macroaggregate formation and intrinsic cementation of loess through carbonates affecting microaggregate stability.
