Summary: This study aimed to quantify and compare soil bacterial and fungal biomass in 513 European soils under different land uses and climates. It was found that bacterial biomass was highest in grasslands, followed by croplands and forests, with the highest levels observed in temperate climates. On the other hand, fungal biomass was highest in forests and favored by colder environments. This study provides a better understanding of the combined effects of land use and climate on soil bacterial and fungal biomass in Europe.

Summary: The excessive use of nitrogen fertilizer has led to serious environmental problems in the North China Plain. This study investigated the variations in soil bacterial communities and denitrifiers in subsoils under different land-use types. The results showed that NO3--N accumulated in the deeper soil layers in apple orchards, increasing the risk of leaching. The soil bacterial community structure and denitrifier abundance varied with soil depth and land-use type, highlighting the importance of subsoils in mitigating nitrate leaching.

Summary: Climate change and land-use intensity impact soil microbial communities, with future climate conditions having less influence on soil microbes while management intensity of land-use has strong effects. Low-intensity management measures can promote soil ecosystem functions such as efficient carbon storage and nutrient cycling under different land-use and climate change scenarios.

Summary: The impact of land use and land cover change (LULCC) on soil organic carbon (SOC) stock is uncertain and largely unknown due to the choice of land use datasets. Using a process-based model, this study investigated the global SOC changes driven by six LULCC datasets and found significant differences in SOC loss estimates. These differences were mainly attributed to changes in vegetation net primary production in boreal and temperate forests and were more pronounced in low latitude regions. The accuracy of LULCC data is crucial for determining the global carbon budget, highlighting the need for harmonizing satellite observations and inventory data.

Summary: Soil microbial communities are influenced by soil types and land use. This study investigated contrasting soils of natural forest and cropped vineyard in New South Wales, Australia and found that land use affected the bacterial community distribution in the topsoil, while soil types influenced the assembly of microbial communities in the subsoil. The study also revealed a decrease in topsoil organic carbon in the vineyard compared to the forest, which was correlated with changes in C-related genes and potentially accelerated carbon loss.

Summary: The restoration of degraded lands and minimizing land degradation are important tasks in global environmental land management schemes. Soil organic carbon (SOC) is a key indicator of soil productivity and influences soil ecosystem services. Detecting changes in SOC stock within a short timeframe presents a challenge for land managers. This study aimed to identify early indicators of changes in SOC stock and their drivers by synthesizing global data on the impacts of land use change on SOC fractions and soil structural properties. The conversion of arable lands to forests and grasslands resulted in a significant increase in SOC fractions and soil structural stability. The study also found that certain SOC fractions, particularly particulate organic C and organic carbon stored in small macroaggregates, were strongly correlated with total SOC and can serve as suitable indicators of short-term changes in SOC stock. Further field studies are needed to validate the findings of this study and assess the applicability of SOC metrics under different land use change scenarios.

Summary: The study demonstrates that soil fertility in temperate fruit plantations in the Northwestern Himalayan region is lower compared to fallow fertile lands, with poorer soil physico-chemical characteristics and nutrient storage capacity. Soil organic carbon and various nutrients are less in temperate fruit plantations than in fallow lands.

Summary: Pathogenic bacteria can be transported through the subsurface environment to contaminate drinking water, with behaviors varying based on soil properties and pore networking. This study found that the transport of Escherichia coli 652T7 was significantly influenced by soil depth and structure, with breakthrough percentages increasing with depth due to decreases in organic matter content, free iron oxides, and zeta potential with soil depth. Larger breakthrough percentages from intact soil cores compared to repacked soil cores were attributed to the presence of larger macropores, lower pore connectivity density, and reduced access to attachment sites in intact soils.

Summary: This study in the semi-deciduous forest zone of Ghana found that forestland had higher soil organic carbon concentration and carbon stock compared to arable land and oil palm plantation, with arable land emitting more CO2. Soil carbon stock had a significant impact on CO2 emissions in different seasons, with soil temperature playing a major role in both dry and wet seasons.

Summary: Bacteria play essential roles in soil health maintenance, and real-time monitoring of their activity levels can provide insights into soil quality, nutrient availability, and future crop yields. A non-destructive technique for monitoring cellulase activity of microorganisms in targeted ecosystems has been demonstrated using a cellulose acetate membrane. The proposed method shows potential for in-field measurements and real-time assessment of microbial activity, with implications for precision agricultural applications.

Summary: Photodegradation contributes to similar leaf litter mass loss rates in mesic environments and drylands, despite water limitations in the latter. Our study in the Southern Appalachian Mountains showed that during the non-growing season, exposure to maximum solar radiation led to decreased proportions of oxidized lignin relative to other carbon compounds in leaf litter. This phenomenon was particularly strong on south-facing slopes with higher solar radiation levels.

Summary: This study found significant changes in biopolymers (lignin, substituted fatty acids, amino sugars) in soil after five years of aboveground litter addition or removal treatments in a temperate forest, suggesting potential impacts on soil organic carbon composition and stability. Although soil nitrogen and carbon contents were not affected, the presence or absence of aboveground litter had a selective effect on the chemical composition of soil organic carbon in different soil depths.

Summary: This study investigates the thermal runaway mechanisms of Prussian blue analogs in nonaqueous sodium- and potassium-ion batteries, revealing a new runaway mechanism that does not involve oxygen evolution, and identifying safety issues related to cyanide release and exothermic reactions with the electrolyte. Calorimetric studies at the full-cell level show mitigated heat generation but lower initiation temperature of runaway compared to conventional systems, suggesting that PBA materials cannot be considered as safe cathodes and highlighting the importance of crystal defects and trapped water content in thermal safety.

Summary: Streams and rivers integrate and transport particulate organic carbon (POC) from various sources, especially during storm events. The study in Iowa, U.S.A. identified a temporal sequence of POC inputs during storms, with significant changes in POC suspended in the water. The longitudinal evolution of the POC signal downstream has implications for understanding soil erosion and organic geochemical sedimentary records.
