Summary: Agricultural practices have a significant impact on soil fauna abundance and diversity. This study examines the response of soil macroinvertebrates to different rice farming pathways, showing that wetland conversion to rice paddies can affect macroinvertebrate richness and diversity. The results also highlight the importance of soil environment in influencing the distribution of macroinvertebrates.

Summary: Lime application has been shown to improve crop yield in Australian farming systems. A meta-analysis of 86 field trials revealed an average 12% increase in yield with a range from 0 to 185%. Sites with lower pH levels showed greater benefits from liming, and the best results were seen when lime application exceeded 2.5 t ha(-1) and had been applied for over three years, with maximum response occurring after four to eight years.

Summary: The hydrological response of a subtropical catchment in Serra da Mantiqueira, Brazil, and its four sub-catchments were investigated. Baseflow played a vital role in sustaining streamflow during the dry and wet seasons. Soil moisture did not synchronize with streamflow, showing increases in early wet season followed by streamflow increase and decreases in late wet season followed by streamflow decrease. The study provided consistent estimates of flows and threshold behaviors, contributing to understanding runoff generation at the catchment scale.

Summary: Metal-rich fumes released during ore smelting result in widespread anthropogenic contamination. Environmental archives such as lake sediments provide records of deposition on lake and terrestrial surfaces from ancient mining and smelting activities. However, little is known about the buffering effect of soils in remobilizing metals through runoff and erosion, leading to persistent contamination long after metallurgical activities have ceased. This study focuses on assessing long-term remobilization in a mountainous catchment area.

Summary: By using a random forest classification method, selected input data layers including potential solar radiation, distance from the closest streambank, streambank slope gradient, topographic wetness index, flow accumulation, and vegetation cover were able to accurately predict areas prone to soil piping in semiarid regions. The study also found that potential solar radiation and tree shading contribute significantly to soil cracking and piping development, while tension cracks in steep streambanks are also closely related to the formation of soil pipes. These findings have important implications for future research.

Summary: This study investigates the soil-plant interaction and the impact of different land use types on plant stress and soil parameters using field measurements and satellite-based data. The results show significant effects of land use types on plant stress and soil parameters. The comparison between field measurements and satellite-based data demonstrates a strong correlation between the two methods.

Summary: Climate change affects nutrient exports in catchment stream water through high-discharge events. Colloidal exports of N, S, and P vary between late winter and spring. Phosphorus is mainly transported by colloids in spring, while nitrogen and sulfur are predominantly dissolved during both seasons.

Summary: Computer-based coupled soilscape-landform evolution models can estimate the erosion potential of a landform over geological timescales and help understand soil-landform relationships. This study used the SSSPAM and CAESAR-Lisflood models to simulate the evolution of a natural catchment and compared the results with field measurements. Both models accurately predicted erosion rates and produced similar geomorphological patterns. The findings demonstrate the ability of SSSPAM to predict erosion and soil distribution at the catchment scale, providing confidence for Soilscape predictions in various landscapes.

Summary: Ephemeral gullies are important erosion features that lead to significant soil loss and sediment production, mainly influenced by rainfall, slope, tillage, and crop management. Cross-slope cultivated areas are more susceptible to severe erosion compared to areas cultivated up and down the slope, with soybean fields experiencing more serious erosion than corn fields.

Summary: SWC is a key variable in land surface processes and can be studied using CRNS technology. This study presents a new methodology for exploring SWC dynamics in humid environments at the catchment scale and its value in rainfall-runoff modeling calibration. The study combines static CRNS data with snapshots at key soil-land use units to generate SWC time series and examines the suitability of CRNS calibration in different soil types.

Summary: This study examines erosion processes and their impacts on forest management in the hilly terrains of the Crveni potok catchment in southeastern Serbia. The study identifies different erosion types and discusses the factors influencing erosion, such as soil density, slope, rainfall, and vegetation characteristics. Various remote sensing and geospatial techniques are used to assess erosion factors, and conversion models are used to estimate soil erosion rates. The study provides valuable insights into prioritizing soil conservation and implementing site-specific remediation measures for sustainable forest management.

Summary: Soil acidification is a major global issue. This study examined soil pH changes in data from 1162 papers published in China between 1996-2000 and 2016-2020, using Geodetector to analyze the influencing factors. The results showed that 58.4% of the collected data pairs exhibited significant acidification. Certain soil types, such as Alfisols, desert soils, primarosols, semi-aqueous soils, and aqueous soils, experienced significant acidification. Soil pH decreased by 0.39 on construction land and 0.12 on cultivated land, while forest land and grassland did not show significant pH changes. Nitrogen deposition, precipitation, sulphur deposition, temperature, and vegetation planted in the soil were found to have a significant impact on soil acidification. This study provides important scientific insights into soil pH changes and offers suggestions for soil remediation measures.

Summary: Managing phosphorus is a global priority for environmental water quality. A study in Western Australia's Fitzgerald River catchment found that dissolved phosphorus transport was dominant, with physical filtering methods like riparian vegetation proving ineffective in restricting phosphorus transport into streams. Evidence-based fertiliser advice could help reduce dissolved reactive phosphorus losses without yield loss.
