Summary: Large-scale afforestation on the Loess Plateau of China may lead to increased soil moisture deficit and SOC loss, especially in downslope areas. Natural grassland, on the other hand, exhibits low water depletion and high SOC sequestration. Therefore, a vegetation restoration strategy involving afforestation of downslope patches within a contiguous grassland matrix may be an effective approach.

Summary: This study utilizes a UV-Vis submersible spectrophotometric probe to measure the concentration of nitrate nitrogen in a high-elevation pond. Through continuous measurements and analysis of stable isotopes, meteorological data, and water temperature, the study examines the dynamics of nitrate in response to changes in meteoclimatic conditions. The results highlight the significant influence of summer precipitation, snow melt, and temperature on nitrate concentration, with short-duration meteorological events causing rapid variations. Additionally, the study reveals the important role of in-pond biological processes and the impact of heavy rainfall events on nitrate trends in high-elevation ponds.

Summary: This study develops a probabilistic framework combining imbalance handling and ensemble machine learning for landslide susceptibility mapping. It overcomes limitations of existing landslide susceptibility maps and successfully develops India's first national-scale machine learning-based landslide susceptibility map. The framework demonstrates high accuracy, robustness, and generalizability, and identifies new landslide susceptible zones in India.

Summary: Mud volcanoes in northwestern Colombia are used by local people as affordable recreational and wellness centers, particularly for pelotherapy. This research aims to determine the potential therapeutic value of the solid and liquid fractions of the muds sampled from these volcanoes through geochemical and mineralogical analysis. The study found that the muds are suitable for use by the local population due to their extremely low levels of contaminants harmful to human health.

Summary: Agricultural intensification has led to severe degradation of croplands in China. Converting degraded croplands to grasslands can increase soil organic carbon and nitrogen content, but may decrease soil pH and available phosphorus. The duration of conversion and mean annual precipitation are major factors influencing soil changes.

Summary: By studying soil samples from different slope directions along an elevational gradient in a mountain ecosystem, we found that soil bacterial diversity and microbial functions exhibit distinct elevational patterns, which are consistent across slope directions. The bacterial diversity shows a hump-shaped pattern, while microbial functions exhibit a linear increasing trend. Additionally, the beta diversity pattern of soil bacteria is significantly influenced by elevational distance decay relationships. Soil bacterial diversity patterns are determined by transitions in community assembly processes, whereas microbial functions are mainly influenced by bacterial community composition.

Summary: This study investigated the effects of soil arthropod communities from cereal-based agroecosystems on wheat plant growth and above-belowground interactions. The results showed that wheat grown in soils with arthropod communities had better growth and defense against aphids, compared to wheat grown in soils without arthropod communities.

Summary: This study investigates the effects of erosion degradation and long-term manure fertilization on soil properties and crop yield in Northeast China. Results show that erosion degradation and manure fertilization have lasting impacts on soil physical structure throughout the soil profile, while their effects on soil nutrient properties are focused in shallow layers. Manure fertilization significantly improves soil functional index (ISI) and maize yield for degraded soils. Erosion degradation has a greater influence on ISI and maize yield than manure fertilization.

Summary: The spatial variations in soil aggregate stability and erodibility in the Mollisol region of northeast China are influenced by soil properties, particularly total nitrogen, soil organic carbon, and bulk density. Factors such as available potassium, saturated conductivity, and soil texture also play important roles in driving the variations of soil aggregate stability and erodibility.

Summary: The intensification of agricultural systems, such as vegetable production, to meet the global food demand has led to increased soil compaction and changes in soil physical properties. This study investigated the effects of vegetable cropping systems on highly weathered Oxisols in the Brazilian Cerrado biome. The results showed that these systems promoted soil compaction, reduced soil porosity, and negatively impacted soil functions and ecosystem services. Improving soil management strategies is crucial for restoring soil functionality and ensuring the long-term sustainability of food production.

Summary: Large amounts of calcium carbonate nanofibres were found in buried archaeological stratigraphy made of recarbonated lime, which could be associated with the manufacture or use of lime products. The phenomenon is widespread, occurring in examples from UK, Latvia, and related nanosized material from Spain. However, the reason for nanofibrous crystallisation in these situations is not currently understood.

Summary: This study investigated the soil organic carbon (SOC) stocks in seasonally frozen ground (SFG) in the Tibet Autonomous Region, China, in 2020 and 2021, and explored the effects of various factors on SOC using partial least squares structural equation modeling (PLS-SEM). The results showed that C inputs exerted the greatest control on SOC, and the influence of these factors decreased with increasing soil depth. Additionally, timely spatial SOC estimates were found to be important for assessing carbon stocks in the context of environmental changes.

Summary: This study compares weathering profiles developed on granite and basalt rocks under different climatic conditions in India. The results show the significance of climate conditions and lithology in controlling weathering advancement. The distribution of major oxides and trace elements is influenced by weathering intensity and formation of secondary minerals. The principal component analysis reveals three components that account for a significant portion of the variance, related to weathering intensity, lithology, and location-specific factors.

Summary: This study tested different methods for generating accurate SOCD maps in the Yangtze River Delta, using soil samples and published literature. Artificial neural network (ANN) and multiscale geographically weighted regression (MGWR) performed well in capturing the spatial pattern and accuracy measures, respectively. Fusion models improved the accuracy compared to individual methods, with the MGNW_F model performing the best. Additional soil samples and method fusion have the potential to enhance the accuracy of SOCD mapping.

Summary: Semi-arid regions in Central Asia are experiencing wind erosion due to steppe conversion and unsustainable farming practices. A study conducted in Kazakhstan used a mobile wind tunnel to assess soil erodibility under real conditions. The results showed significant differences in soil erosion based on initial conditions and mechanical stress, emphasizing the importance of proper soil management to prevent severe events.
