Summary: Agroforestry systems and legume sowing are considered efficient in terms of soil function, with legume-enriched pastures showing higher microbial biomass, diversity, and activity compared to control pastures. There was an increase in soil carbon stocks after sowing, which was related to legume abundance, phosphorous fertilization, and forage yield. The shift in microbial community structure and the positive legacy of increased soil carbon stocks and nutrient fixation by legumes can help enhance pasture productivity and climate-resilience, but further research is needed.

Summary: Constructed wetlands are widely used as low-cost wastewater treatment systems and provide various ecosystem services. Microorganisms in wetland soils play a fundamental role in supporting wetland functions. This study found that both bacterial and fungal abundances increased with wetland age, with bacteria dominating the soil microbial communities in all ages of constructed wetlands. The stress indices showed that microbial stress may be influenced by changes in the availability of in situ nutrients in the wetland soils.

Summary: The presence of shrubs in the Sahel region can maintain soil microbial communities and activity, especially during the dry season. Hydraulic lift and root exudates from shrub roots are likely key factors in sustaining microbial activity. This has implications for nutrient cycling in cropped fields during the dry season, enabling nutrient accumulation for uptake by crops in the rainy season.

Summary: Despite the benefits of plastics in daily life, the accumulation of plastics in the environment, especially microplastics, can cause problems and potential loss of ecosystem services. This study investigated the effects of different types of microplastics on plant growth, soil enzyme activities, and microbial communities. The results showed that microplastics had a positive impact on plant growth but suppressed soil enzyme activities, except for urease activity. Microplastics also altered the structure and metabolic status of the microbial community. It was concluded that microplastics in soil are not benign and measures should be taken to restrict their access to the soil-plant system and food chain.

Summary: This study examines the changes in microbial communities in poplar wood at different stages of succession and finds that the composition and structure of the communities change significantly over time. Bacterial diversity decreases while fungal diversity increases as succession progresses. Additionally, the study reveals that while succession does not affect the composition of microbial communities at the phylum level, specific bacterial and fungal populations become more prevalent as succession proceeds. The findings suggest that bacteria and fungi exhibit different ecological strategies in poplar wood, and understanding these strategies is vital for the biological control of wood discoloration.

Summary: The study used a simulation model to analyze the impact of continuous-cover forestry on CO2 and CH4 emissions in nutrient-rich drained peatland sites in southern Finland. Results showed that the peatland forest acted as a carbon sink with low and medium harvesting intensities, but became a carbon source with high harvesting intensities due to increased soil methane emissions and decreased tree production. The simulations highlight a significant trade-off between maintaining carbon in drained peatland forests and generating harvest revenues.

Summary: This study investigated the impact of machinery-induced soil disturbance on boreal peatland forests. The results showed that soil disturbance directly decreased moss biomass, increased sedge cover, and decreased root production. Additionally, disturbed areas had higher soil CO2 production potential, and soil CO2 and CH4 concentrations compared to control areas. While recovery rates varied, all impacted properties fully recovered within 15 years.

Summary: Climate change can affect the carbon sink function of peatlands by causing warming and drying. We studied the response of fine-root biomass production (FRBP) in two sedge fens in Northern and Southern Boreal zones to warming and drying. The results show that warming increased total FRBP and the proportional share of FRBP in deeper layers, while drying modified root chemistry and reduced the decomposition of sedge leaf litter.

Summary: The global forest carbon stock is mainly found in soil organic matter and understanding the effects of forest management practices on soil carbon stocks and greenhouse gas emissions is crucial for effective climate change mitigation strategies. This study synthesized literature on forest management practices that increase soil carbon stocks and reduce greenhouse gas emissions. Soil processes, such as nitrogen fertilization and peatland hydrology management, play a significant role in soil greenhouse gas balance.

Summary: Aerenchymatic transport plays a crucial role in plant-mediated methane emissions in peatlands, but the control of environmental factors and plant phenology remains uncertain. We investigated the factors controlling seasonal methane flux rate and transport efficiency in various wetland plant species. Our results showed that the flux rate of Carex rostrata was influenced by plant phenology and peat temperature, while other species were insensitive to the investigated environmental variables. Understanding the species-specific methane flux rate and their responses to phenology and environmental factors can greatly improve the estimation of ecosystem-scale methane dynamics in boreal peatlands.
