Summary: This study evaluates the separate effects of earthworms, casts, and mucus on peat soil chemistry, microbial community, and enzymes. The results show that earthworms and their casts have significant negative effects on peat soil dissolved organic C, microbial biomass C, pH and polyphenol oxidase. They also have positive effects on phenolic matters, hydrolase activity, bacterial diversity, and metabolic functions. The effects of mucus on soil properties were similar to those of earthworms, but different on other soil properties. This research provides evidence that earthworms change soil properties primarily through gut processes, indicates the negative effect of earthworms on peat soil C, and calls for monitoring soil fauna to protect C stocks in degraded peatlands.

Summary: The study aimed to evaluate the benefits of using biochar instead of its feedstock in improving soil quality. A pot experiment was conducted to investigate the short-term effects of two organic materials and their derived biochars on maize growth, soil properties, and microbial community. The results showed that straw decreased maize shoot biomass, while straw-derived biochar, manure, and manure-derived biochar increased it. Straw and manure had more pronounced effects on improving soil properties compared to their biochars. Straw and manure reduced bacterial alpha diversity and altered bacterial community composition, while straw-derived and manure-derived biochars had different effects on bacterial diversity and community composition. Straw-derived biochar was found to be more effective in promoting maize growth, while the choice of manure and its biochar should depend on the soil type.

Summary: Biochar-derived dissolved organic matter (BDOM) plays important roles in soil ecosystem by influencing soil properties and providing nutrients to soil microbes. BDOM can either enhance or suppress the growth of certain soil microorganisms depending on its composition and labile organic compound content. This review focuses on the impact of BDOM concentration, feedstock biomass type, and pyrolysis temperature on soil microbial functioning, community structure, and enzymatic activity. Results indicate that feedstock type and pyrolysis temperature affect BDOM characteristics and its interaction with soil microbial communities. Plant-based biochar produced at lower pyrolysis temperatures often contains more aliphatic BDOM, while higher pyrolysis temperatures yield more aromatic BDOM. BDOM from plant biochar has higher specific ultraviolet absorbance (SUVA) and humification index (HIX) compared to manure-based biochar. The SUVA and HIX of BDOM positively correlate with total fatty acid methyl ester content, but negatively correlate with abundances of actinomycetes, arbuscular mycorrhizae, and fungal communities. However, long-term experiments are needed to fully understand the environmental fate of BDOM in biochar-amended soil and its interaction with soil organic matter and microorganisms.

Summary: The study found that the cropping system has an impact on the physical-chemical properties and microbial community of paddy soil. Previous studies mainly focused on the soil 0-20 cm underground. However, there may be differences in nutrient and microorganism distribution at different depths of arable soil. This study compared the organic and conventional cultivation patterns, as well as low and high nitrogen levels, in the surface (0-10 cm) and subsurface (10-20 cm) soil. The results showed that under the organic farming pattern, the contents of total nitrogen, alkali-hydrolyzable nitrogen, available phosphorus, and soil organic matter increased in surface soil, while the organic matter concentration and urease activity decreased in subsurface soil.

Summary: The effects of polyethylene (PE) and biodegradable polylactic acid (PLA) microplastics on soil organic matter (SOM) stability and bacterial community were examined in two contrasting soils under varying temperature conditions. Results showed that microplastics addition significantly increased CO2 emissions and dissolved organic carbon (DOC) contents, with PLA being more susceptible to elevated temperature compared to PE. The presence of microplastics also altered the spectral characteristics of DOC and affected the soil bacterial community. The findings suggest the non-ignorable effect of microplastics on soil organic matter stability and the need to consider the interaction between microplastics and soil environment.

Summary: High latitude regions are experiencing winter climate change, which can affect soil microbial communities and enzyme activity. However, limited knowledge exists on how soil microorganisms in permafrost ecosystems respond to snow cover changes. This study found that the removal of snow had a significant impact on the bacterial community structure during the snow melting period and early vegetation growing season, but no cross-season legacy effects were observed. Snow removal also affected soil enzyme activities, but these effects did not persist into the vegetation growing periods. The seasonal variations in bacterial community and enzyme activity were mainly driven by changes in soil nutrient availability.

Summary: The presence of microplastics (MPs) in wastewater poses significant risks to ecosystems. Constructed wetlands (CWs) are effective in intercepting MPs, but the impact of MP accumulation on CWs' performance is not well understood. This study conducted a 370-day experiment and found that MP accumulation changed the biofilm composition, substrate porosity, and oxygen mass transfer in CWs, leading to a decline in nitrogen removal efficiency. These findings provide insights into the effects of MPs on physicochemical and microbial characteristics in CWs, which can guide the regulation of MPs in wetland environments.

Summary: This study assessed vineyard soils and management practices using soil factors and foliar diagnosis. Soil characteristics and physicochemical properties were determined annually and every four months. The study aimed to evaluate soil quality and establish necessary measures for improvement. The soils had limitations with mechanization, trafficability, and ease of tillage due to sandy loam texture. Phytosanitary treatments and fungicides caused phytotoxic contents of Cu and Zn in the soils without being detrimental to the vines. Soil factors and foliar analysis were adequate for assessing soil and vine condition and improving vineyard soil productivity.

Summary: This study used pyrolysis gas chromatography-mass spectrometry to determine the mass concentrations of microplastics (MPs) and nanoplastics (NPs) in two wastewater treatment plants (WWTPs). The results showed that the mass concentrations of total MPs and NPs decreased during the treatment process, with NPs having a lower removal efficiency than MPs. It was estimated that approximately 0.321 and 0.052 tons of MPs and NPs were released into the river each year based on the annual wastewater effluent discharge. Overall, this study provided valuable information about the pollution level and distribution characteristics of MPs, especially NPs, in WWTPs.

Summary: Agricultural nanotechnology is a powerful tool for improving crop production, but its application during germination can pose challenges. This review evaluates the effects of essential and non-essential element nanoparticles on plant germination. Factors such as dose, treatment time, application method, nanoparticle type, and plant species affect the effectiveness of nanoparticles. pH and ionic strength of the soil also play a role in nanoparticle application. Iron nanoparticles show promising results in improving nutrient uptake and germination, while excess copper and zinc nanoparticles can be toxic and negatively impact germination. Titanium and silver nanoparticles have the potential to improve nutrient uptake, but their effects depend on crop type, particle size, and concentration. Further research is needed to understand the potential environmental and health impacts of nanotechnology in agriculture.

Summary: The contribution of biofilm detachment from different pipes to water quality deterioration has not been quantified or compared. This study analyzed particles at customers' ends and traced their origins to water distribution mains and service lines. The results showed that elemental concentrations of the biofilm in mains were higher than those of service lines, both dominated by Ca. Filter bags were dominated by Fe/Mn. After introducing partial reverse osmosis (RO), Ca significantly decreased in biofilms of mains, but the released Fe/Mn arrived at customers' ends. The ATP concentrations of service lines were higher than mains, which decreased on mains but increased in service lines after introducing RO. According to source tracking results, service lines contributed more than mains to the particulate material collected by filter bags.
