Summary: The effectiveness of leaf- and root-derived ester-bound lipids as biomarkers is highly species dependent and their concentration changes during degradation without a linear trend, suggesting a dependency on species. This variation may be due to differences in the structure and arrangement of individual monomers in cutin and suberin per species.

Summary: Different tillage and nitrogen fertilization practices have significant effects on soil carbon dynamics. Conservation tillage increases specific soil organic matter components, such as long-chain acyclic lipids, cyclic lipids, and simple sugars. Conservation tillage also preserves cutin- and suberin-derived compounds, while lignin-derived compounds are lower compared to conventional tillage. The effects of nitrogen fertilization on soil organic matter compounds and fungal community composition are observed only under conventional tillage, suggesting that the control of nitrogen fertilization on soil organic matter dynamics may depend on the type of tillage practices.

Summary: Conservation agriculture practices such as conservation tillage and crop rotation can significantly impact the composition and turnover of soil organic matter (OM) at the molecular level. Long-term conservation tillage was found to result in changes in soil OM composition, affecting organic carbon concentrations and molecular-level composition, with microbial degradation and OM inputs from crop residues playing key roles. Additionally, interactions between diverse crop rotations and conservation tillage were found to reduce differences in specific groups of compounds, highlighting potential benefits for agricultural soil management.

Summary: Forest ecosystems as global soil carbon reservoirs are affected by climate change factors that change carbon inputs. This study integrated molecular composition data sets of soil organic matter and microbial communities to investigate the effects of detrital input and removal treatments on forest soil carbon dynamics. The results showed that long-term litter additions did not increase soil carbon content, while litter reductions negatively impacted soil carbon concentrations. This highlights the sensitivity of soil carbon biogeochemistry to changes in litter deposition.

Summary: In this study, the dynamics and biodegradation mechanisms of dissolved organic matter (DOM) in eroding agricultural landscapes were investigated. The results revealed that the content of dissolved organic carbon (DOC) was higher in the mid-slope compared to the down-slope, especially at depths of 40-100 cm. The chemical characteristics of DOM differed along the slope, with the up-slope soil containing more microbial-derived substances and the depositional positions rich in humic-like materials.

Summary: This study aimed to investigate the impact of different methanolysis conditions on the depolymerization and monomer release of cutin in cork oak leaves, in order to establish protocols for cutin content determination and composition profiling. Results showed that the reactivity of cutin ester bonds is not uniform and the composition of cutin extracts varies with depolymerization extent. The molar composition of cutin suggests a macromolecular assembly based on glycerol linked to lipid oligomeric chains with moderate cross-linking.

Summary: The experiment showed that microbial activity is lower in the subsoils of Andisols, with decreased SOC persistence at depth. While native SOC mineralization was observed in subsoil horizons after the addition of labile organic carbon and nutrients, the topsoils did not display this behavior, indicating differences in carbon turnover rates between top- and subsoil horizons. This suggests that the physicochemical soil characteristics evolving during pedogenesis play a crucial role in controlling SOC stabilization and destabilization processes in Andisols under temperate old-growth rain forests.

Summary: Adding biochar to compost as a soil amendment is increasingly popular, but little is known about the evolution of material properties of biochar-compost mixtures after exposure to physical weathering. This study found that biochar-compost interactions can reduce mass loss and retain fixed carbon, leading to positive effects on plant growth. As weathering progresses, carbon mineralization of biochar-compost mixtures increases, potentially benefiting plant growth.

Summary: Alley cropping agroforestry systems were found to improve soil quality compared to monocropping systems, especially in terms of microbiological soil quality indicators. The introduction of tree rows in the system led to spatial heterogeneity in chemical indicators, microbial biomass, activities, and community structure at the plot scale. The overall soil quality index of the entire alley cropping plot significantly increased relative to the monocropping plot after 21 years of agroforestry practice.

Summary: This study assessed the fate of C and N compounds during the composting process of cattle and pig slurry anaerobic digestates. It found that there was no isotopic discrimination during composting, indicating the previous stabilization of the manure. Additionally, the composts increased N values and delta N-15 soil values, and the plants grown on compost-amended soils showed higher N and delta N-15 abundance compared to control and inorganic fertilized plants. Overall, the delta N-15 abundance of anaerobic digestate composts could be a useful tool for detecting the type of fertilizer used in agricultural production.

Summary: This study examined the biosynthesis and characterization of selenium nanoparticles (SeNPs) using two endophytic selenobacteria. The results showed that both strains were suitable for producing SeNPs with different properties. The SeNPs were surrounded by the proteins, lipids, and polysaccharides of bacterial cells, and the functional groups present in SeNPs from one strain were higher in number than in the other strain. The findings support the potential of these endophytic strains as biocatalysts for producing high-quality Se-based nanoparticles, and future efforts should focus on evaluating their bioactivity and determining how the different features of each SeNP modulate their biological action and stability.

Summary: It is estimated that if all legal active mining sites in Brazil are exploited over the next decades, it could result in the emission of 2.55 Gt CO2eq, largely due to the loss of vegetation and soil. To offset these emissions, the construction of soils from mine and other wastes (Technosols) is proposed, which could potentially offset up to 60% (1.00 Gt CO2eq) of soil-related CO2 emissions and restore important soil-related ecosystem services.
