Summary: Agroecosystems have a large potential for soil carbon sequestration, and cover cropping is an effective management practice that can enhance soil carbon while providing other ecological and agronomic benefits. However, the distribution of added carbon across different soil organic carbon fractions is still not well understood. A meta-analysis of 49 studies showed that cover cropping significantly increased both particulate organic carbon (POC) and mineral-associated organic carbon (MAOC) concentrations and stocks, with POC being more responsive than MAOC. This information can guide future efforts in carbon sequestration and sustainable agriculture.

Summary: This study examines the effects of phosphogypsum application on the physicochemical properties and microbial community of saline-alkali soil. The results demonstrate that phosphogypsum significantly improves soil properties, reducing salinity and alkalinity while enhancing nutrient structure and increasing the utilization efficiency of carbon, nitrogen, and phosphorus. Phosphogypsum also significantly improves fungal community diversity, primarily influenced by soil water content, total organic carbon, soil organic matter, total nitrogen, and sodium ion. The findings indicate that combining rice planting with phosphogypsum application effectively modifies saline-alkali soil, regulates fungal community structure, and enhances long-term soil health.

Summary: The study found that irrigation in New Zealand significantly reduced soil carbon and nitrogen stocks, with greater losses observed at greater durations of irrigation and lower aridity levels. The impact of irrigation on soil C and N was negatively related to aridity, with increasingly significant carbon losses observed at sites with higher precipitation levels. The results suggest that a new equilibrium may be reached with lower carbon stocks in irrigated grasslands compared to unirrigated grasslands.

Summary: Population growth and increasing food demand contribute to soil degradation and decrease in soil organic carbon (SOC) stock in agriculture. Agroforestry systems like alley cropping are gaining attention for their potential to maintain and increase SOC in agroecosystems. This study aimed to expand knowledge on SOC in alley cropping systems by conducting a meta-analysis and evaluating the impact of introducing trees into agricultural landscapes. Results suggest that beneficial effects on SOC are observed approximately ten years after adopting alley cropping practices. Moreover, the effect of alley cropping is more pronounced in regions with lower initial SOC concentration and in tropical regions compared to temperate zones.

Summary: The way chemicals affect soil biological properties, including enzymatic activities, can reveal the soil's potential to maintain biochemical processes and soil fertility. This research investigated how soil type and depth, as well as the rate and application time of the pretilachlor herbicide, influenced soil biological properties in paddy fields in Babol, Iran. The results showed that soil organic matter content played a role in mitigating the herbicide's effects on soil biological activities and that deeper soil depths had lower biological activities. The use of the herbicide generally increased soil biological activities, except for urease activities, and was linearly related to soil depth. Soil microbial biomass was found to be a more suitable indicator for estimating soil microbial respiration. Soil organic matter can reduce the toxicity of pretilachlor on soil biological activities.

Summary: Cover crops play a crucial role in increasing soil fertility and mitigating climate change through nutrient recycling and organic matter buildup. A study on the short-term effects of incorporating winter vetch into a cover crop mixture found that higher soil fertility led to a significant reduction in relative net phyllo- and rhizodeposition, despite an increase in cover crop biomass. Adjusting for unrecovered root fragments significantly reduced the estimated phyllo- and rhizodeposition, highlighting that many previous estimates may have been overestimated. Autumn cover crop usage provides a key opportunity for carbon storage, with both aboveground biomass input and belowground carbon investment being important factors.

Summary: Viruses are abundant and important in ecosystems, and the two methods of whole genome shotgun metagenome and viral-like particle enriched metagenome sequencing are commonly used for comparing viruses in different environments. In this study, both methods were applied to investigate the stool virome in HCC patients and healthy controls, and they both successfully identified altered viral profiles in HCC patients. Ultra-deep sequencing recovered more viruses, and VLPM method can detect RNA viruses. Using both methods would capture different parts of the total virome and identify shared and specific viral signatures.

Summary: This study utilized melt-extrusion 3D printing to prepare biodegradable composite scaffolds, containing bioactive glass, calcium sulfate hemihydrate, and polylactic acid. The compressive strength of scaffolds was comparable to that of human bone tissue, and in vitro and in vivo experiments demonstrated good biocompatibility. The scaffold maintained biomechanical stability of bone defects for 20 weeks without causing liver or kidney damage in animal experiments. Scaffold degradation was accompanied by trabecular bone and vessel neogenesis. The PLA-CSH-BAG group exhibited satisfactory bone defect repair effect compared to the PLA and control groups. In conclusion, the biodegradable porous scaffold is proposed as a safe and effective approach for bone defect repair.
