Summary: Converting grassland to arable cropping can lead to decreased soil organic carbon (SOC) stocks, impacting soil and climate protection goals. However, using direct drilling in forage production systems like silage maize can prevent SOC stock degradation without reducing herbage yield. Long-term practices, such as a three-year grass phase followed by three years of silage maize, can help maintain SOC stocks.

Summary: The study found that conversion of wetlands to croplands, forestlands, and construction lands led to an increase in C:N ratios, a decrease in δ13C values of SOC compared to the original wetland, and faster lignin decomposition rates in wetlands. The beta values decreased from croplands to construction lands, forestlands, and wetlands, indicating faster turnover of SOC. However, SOC content and storage were significantly higher in wetlands compared to other land use types.

Summary: Global environmental change can substantially affect soil carbon storage and dynamics in agricultural ecosystems. However, there is still limited understanding of the relationship between soil organic matter (OM) composition and environmental factors. This study analyzed soil samples from agricultural sites in Canada and New Zealand and found that the preservation and degradation of specific soil OM components varied. Furthermore, different environmental constraints were observed for specific OM components in agricultural ecosystems, indicating that preservation mechanisms are not uniform across different soils and climates.

Summary: Stable nitrate isotopes and stable water isotopes were used to identify nitrogen sources and N-biogeochemical transformation in tap water sources from 11 water purification plants in South Korea. The land use type in the water supply basins influenced the contribution of different nitrogen sources and exhibited large seasonal and spatial differences. Understanding the isotope fractionation due to N-biogeochemical transformation is important for interpreting the origin and fate of NO3-. The findings provide a basis for N source control strategies to ensure tap water quality in complex land use areas.

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: This study investigated the effects of organic fertilizer (poultry manure compost), mineral fertilizer (rock phosphate), and their mixture on the transfer of organic carbon (OC) from plants to soil. It found that poultry manure compost and its mixture with rock phosphate increased root biomass and root-derived OC transfer to active pools compared to rock phosphate alone. Soil amended with poultry manure compost also had higher microbial biomass contents than soil with mineral fertilization.

Summary: Biochar aging affects its interaction with water, and physical aging has a stronger influence on water mobility and dynamics in biochar compared to biochemical aging. Physical aging leads to the disappearance of larger pores in biochar, while biochemical aging enriches oxygenated functional groups. Both types of aging increase the interaction between biochar and water, as observed through 1H NMR relaxometry.

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.
