Summary: This study investigated the conversion of agricultural biomass waste (specifically, spent mushroom substrate) into syngas via pyrolysis. The experimental data highlight the important role of carbon dioxide (CO2) in enhancing carbon monoxide (CO) yield through gas-phase reaction. The addition of a Ni-based catalyst further enhanced the mechanistic role of CO2.

Summary: The study aimed to investigate the functional mechanisms of spent mushroom substrate (SMS) and SMS-derived biochar on phytoremediation of soil heavy metal contamination. The results showed that additional biochar application decreased the soil's available Cd content and enhanced phytoremediation performance by increasing plant biomass. Both SMS and biochar applications enhanced microbial resistance to heavy metals and stimulated microbial activities in contaminated soil.

Summary: This study introduced a novel application strategy to turn conventional spent mushroom substrate (SMS) into renewable biochar SMS in mushroom production. The renewable SMS demonstrated greater mushroom yields and faster fruiting time compared to conventional SMS. Biochar retained substrate moisture and reduced nutrient loss, contributing to the increased mushroom yields. Further analyses confirmed the food safety of oyster mushrooms cultivated using renewable SMS. The economic analyses indicated a higher output-to-input ratio for renewable SMS compared to conventional SMS. Additionally, the basic properties of renewable SMS and its effect on mushroom growth remained consistent even after repeated use.

Summary: The study found that biochar feedstocks have different effects on CH4 and N2O emissions in soils with different water contents. MS biochar performed better in reducing N2O emissions compared to FS biochar, but increased CH4 emissions. Additional research is needed on the interactions between biochar, water content, and soil GHG emissions.

Summary: The application of spent mushroom substrate (SMS) significantly improved soil pH, organic matter content, and reduced the availability of Cd in soil, leading to decreased Cd uptake in rice tissues and increased rice production. The combined use of SMS-A and SMS-B can be a potential method for remediating Cd-contaminated paddy soil.

Summary: This study focused on converting various types of spent mushroom substrate (SMS) into fuel pellets for low-emission bioenergy production. The SMS pellets met international standards for solid biofuels except for ash content, and showed potential for utilization in waste-to-energy pathways within a circular economy. SMS from A. subrufescens grown on compost with soil casing exhibited the best properties for high-performance pelletization, emitting lower levels of CO2, NOx, SO2, and volatile organic compounds compared to reference pellets from pinewood sawdust.

Summary: This study evaluated the novel application of a mineral-rich biochar derived from a spent Agaricus bisporus substrate for the removal of Cu(II), Zn(II), and Cd(II) from aqueous solutions. The adsorption mechanisms varied with the pyrolysis temperature, with ion exchange dominant at low temperatures, coordination with pi electrons at moderate temperatures, and mineral precipitation at high temperatures. The mutual effect of minerals and heavy metals played a significant role in the sorption mechanism.

Summary: The edible mushroom industry has led to the generation of a significant amount of spent mushroom compost (SMC), which is considered as agricultural waste. In this study, SMCs from shiitake and black fungus cultivation were converted into porous biochar products through pyrolysis. The pore and chemical properties of the resulting biochar products were studied and correlated with the pyrolysis temperature. The research found that the pore properties of the biochar products increased with higher pyrolysis temperatures.

Summary: The study found that adding litter to the soil generally has positive effects, while removing litter may have different effects on soil properties, especially on soil nutrients, microbial communities, and enzymatic activities. In addition, enzymatic stoichiometry is more influenced by soil depth, and soil microbial communities and enzymatic activities exhibit asynchronous responses with increasing profile depth.

Summary: Leaf-harvesting in Cinnamomum camphora plantations potentially enhances N2O emissions from the soil, while phosphorus management mitigates this enhancement. The study provides implications for the management of leaf-harvesting C. camphora plantations in terms of soil nutrient conservation and mitigation of forest soil GHG emissions, particularly in subtropical regions with intensive leaf-harvesting and fertilization practices.

Summary: The study investigates the impact of nitrogen deposition and phosphorus addition on the mobility and equilibration of trace elements in forest ecosystems. Different trace elements showed varied responses to nitrogen and phosphorus treatments, with phosphorus having a greater influence on element mobility. Forests adapt to environmental changes by adjusting the tradeoff between capture and resorption strategies, with element mobility being dominated by phosphorus rather than nitrogen.

Summary: This study compared the effects of nitrogen and phosphorus addition on leaf traits and growth of Schima superba seedlings through field and pot experiments. The results showed that nitrogen addition had a stronger impact on leaf traits and growth in the pot experiment, while the effects were weaker in the field. The findings from the pot experiment might exaggerate the impact of nitrogen deposition on forest plants.

Summary: Urbanization increases the rate of greenhouse gas emissions, including nitrous oxide (N2O), which contributes to global warming. This study examined the effects of urban-rural gradients, nitrogen (N), and litter input on N2O emissions from Cinnamomum camphora plantation soils. The results showed that urban soil had significantly higher N2O emissions compared to suburban and rural soil. Litter removal also increased N2O emissions in all soil types. The study suggests that the retention of litter is important in mitigating N2O emissions, providing a potential strategy for reducing greenhouse gas emissions.

Summary: Changes in litter input and understory vegetation, caused by climate change and human activities, have significant effects on soil microbial communities and functions in plantation forests. This study conducted a field experiment in a subtropical Chinese fir plantation and found that aboveground litter and soil depth altered the effects of understory vegetation removal on soil physicochemical properties primarily through soil microbial biomass and enzyme activities. The study highlights the integrated feedbacks of microbial structures and functions along soil profiles in response to litter and vegetation interactions in subtropical forests.

Two studies were conducted to identify influencing factors using social cognitive theory (SCT) and grounded theory, and to analyze different configurations using the fsQCA method. The results showed that there were four configurations for the formation of academic information avoidance behavior, which were categorized into three types. This study contributes to the theory of academic information avoidance behavior and provides recommendations for young researchers and university libraries.
