Summary: The study found that afforestation with Pinus ponderosa in the Patagonian Andean Region's volcanic soils can increase organic matter content and improve soil structure, slowing down erosion processes. However, soil changes vary significantly depending on initial organic matter content and plantation age. Maintaining covered afforestation may be an effective way to control erosion.

Summary: Land management legacies and climate change have caused shifts in forest structure and fire regimes in western ponderosa pine forests. This study assesses recent fire effects in these forests and finds that severe burns lead to tree losses and vegetation shifts. The findings contribute to our understanding of the ecological outcomes of climate change and disturbance regimes, and provide guidance for land management efforts.

Summary: This study aimed to compare the microbial contribution to soil organic carbon (SOC) accumulation in Andisols and non-volcanic ash soils (Inceptisols). The results showed that microbial contribution is critical for enhanced SOC in forest Andisols, but not in agricultural Andisols.

Summary: Forest plantations with exotic species in the southern hemisphere have been extensively planted for soil conservation and shallow landslide mitigation. However, their suitability in achieving protection goals is debated. This study applied a biogeomorphic framework to analyze the link between land use, soil conservation, and natural hazards in Chilean Patagonia. The findings suggest that different land uses, such as primary and secondary forests, Pinus plantations, wildfire sites, and pastures, have varying effects on soil stability and landscape resilience.

Summary: Soil researchers analyze the properties and dynamics of soil in relation to land use change to gain a better understanding of the soil system state. Their evaluation of tilled, abandoned, and forest soils using interquartile ratio and entropy indices revealed differences in soil properties based on agrotechnics and the state of the system. The study also suggests that the interquartile ratio can be an alternative to entropy in assessing the response of soil properties.

Summary: The paper discusses the aerosol measurements taken during the volcanic eruption of Cumbre Vieja in La Palma Island, showing that the height of the volcanic plume varied significantly and steadily increased after the eruption started. The ash mass concentration was evaluated using a polarized lidar instrument, with the highest estimated concentration reaching 800-3200μg m(-3).

Summary: A new species of the genus Roholtiella, Roholtiella volcanica sp. nov., was discovered during the study of biodiversity of cyanobacteria in Gorely volcano soils. Morphological, ecological, and phylogenetic analyses were conducted to describe and classify the new species. This research contributes to the understanding of cyanobacterial diversity and taxonomy.

Summary: The productivity and sustainability of planted forest ecosystems are closely related to soil nutrients and the microbiome. This study investigates the long-term effects of land-use history on soil microbial communities and their responses to management practices. The findings suggest that past land-use can have lasting impacts on microbial communities and their ability to adapt to changes in the environment.

Summary: The study suggests that land-use changes have a negative impact on soil C content, but the stability of soil organic matter mainly depends on site characteristics rather than land use practices. The research also found that the composition of organic matter in soil is influenced by mineral components.

Summary: Land use has a significant impact on soil microbial and physico-chemical properties. Agricultural practices in the past were found to have influenced soil properties, including reduced microbial biomass and activities, increased phosphorous content and pH. However, the effects of land use did not alter the microbial and physico-chemical responses to seasonal contrasts. After at least 60 years of reforestation, the soil recovered its pristine physico-chemical and microbial functional properties.

Summary: Geopolymers have gained attention as construction materials, with this study investigating the use of volcanic ash and ground granulated blast furnace slag as replacements for portland cement to stabilize sandy soils. Predictive modeling using artificial neural networks and sensitivity analysis identified the Si/Al ratio as the parameter most affecting compressive strength.

Summary: This study investigated the relationship between permeability and microstructure of saline-alkali soil in the floodplain of southwestern Shandong Province through freeze-thaw cycles. The results showed that soil microstructure and pore size distribution play a crucial role in determining soil permeability. The increase in freeze-thaw cycles led to stronger soil permeability, with a shift towards smaller pore sizes in the soil.

Summary: Forest soils in different zones of a temperate forest in Mexico showed significant differences in soil quality index, with the zone of preserved pine forest having the highest SQI values. Linear score indices from PCA were more effective in differentiating calculated SQI values.
