Summary: The study found that silver nanomaterials did not significantly impact the density, activity, function, and diversity of soil microbial communities. However, the positive ionic silver treatment showed suppression of microbial activity and an increase in specific microbial populations, indicating a need for further investigation.

Summary: Microbial inoculants have gained popularity for regulating plant traits and productivity in the past decade as a sustainable and gentle alternative to fertilizers, pesticides, and genetic modification. However, the potential for microbial invasions poses a risk, leading to the need for measures outlined in the TREE approach to prevent such invasions and stimulate proactive discussions on best practices.

Summary: The use of reclaimed water in agriculture is a promising alternative to alleviate pressure on freshwater supplies, but may introduce micropollutants into the environment. Studies have shown that an antihypertensive drug has both dissipation and accumulation effects in soil-earthworm microcosms.

Summary: Copper oxide nanoparticles can be used as an alternative to conventional copper in agriculture, but they have negative effects on soil organisms, particularly in clay-rich soils, where the interactions between nanoparticles and clay are believed to be responsible for the observed toxicity.

Summary: The study proposes a function-first framework to predict how microbial communities influence ecosystem functions, linking microbial function to community composition and structure. It describes the dependence of microbial functions on environmental factors and combines functional response curves with current environmental conditions to predict the contribution of the whole community to ecosystem function. Ultimately, indicator taxa may be used as a diagnostic tool to enable predictions of ecosystem function from community composition.

Summary: Evidence suggests that controlled irrigation (CI) and biochar application (BA) have an impact on soil microbial genes related to nitrogen conversion in paddy fields. The application of biochar increases the abundance of nitrogen-fixing bacteria, leading to higher levels of ammonium and nitrate in the soil. Moreover, biochar treatment also increases the microbial diversity in the paddy field. The combined use of CI and BA affects soil nitrogen content, temperature, pH, and electrical conductivity, which in turn affect microbial genes related to nitrogen transformation.

Summary: This study evaluated the ecotoxicology of silver nanocomposites in films and investigated their antimicrobial properties. The results showed that the addition of silver nanoparticles and titanium nanoparticles did not contaminate the environment and did not interfere with embryonic development.

Summary: This study investigates the effects of silver and hematite nanoparticles on common bean plants and soil bacterial communities. The application of nanoparticles did not significantly impact plant growth, but did alter the levels of certain heavy metals in plant tissues. The diversity, structure, and functional profile of the soil and rhizosphere bacterial communities were minimally affected by the nanoparticles.

Summary: This study compared the effects of direct exposure to AgNPs or indirect exposure via sewage sludge contaminated with AgNPs on earthworms and soil microbial communities. Results showed that direct exposure to AgNPs led to a decrease in potential carbon respiration in the soil, while the addition of sewage sludge had a greater impact on soil microbial diversity. The formation of Ag sulfides in sewage sludge reduced the impact of AgNPs on earthworms and soil microorganisms compared to direct addition.

Summary: Mining activities can cause long-lasting residue pollution in the surrounding environment. A study on a 100 year-old mine showed that potentially toxic elements have ecotoxicological impacts on microbial activity and diversity. Furthermore, assessing the relationship between physicochemical properties and microbial diversity and activity can help stakeholders define appropriate management strategies.

Summary: This study investigated the effects of water-treatment residuals (WTRs) on soil ecology through a 7-week outdoor mesocosm trial, finding that WTRs had impacts on earthworm growth and soil respiration, but overall disturbances to soil ecology were minimal.

Summary: This study analyzed the impact of environmental properties on the taxonomic and functional diversity of microbial communities in Antarctic soils. It found that elevation is the key factor affecting the structure and composition of soil prokaryotic communities, with higher elevations harboring less diverse communities with distinct genomic attributes and life-history strategies. This study highlights the importance of studying community shifts across environmental gradients to improve our understanding of microbial diversity and adaptation strategies in extreme environments.

Summary: Considering the increasing global land degradation and desertification, understanding the modulation of soil microbial communities by these drivers is crucial in mitigating these processes. This study assessed the effects of land degradation, restoration, and native forest on soil microbial communities in a semi-arid region in Northeastern Brazil. The results showed that land degradation led to changes in microbial community composition and decreased microbial diversity. However, the restored area exhibited more resilience, suggesting that microbial communities can recover their functions through sustainable practices. Furthermore, degraded lands resulted in a loss of functions related to carbon dynamics in the system. This study provides important evidence that land restoration practices can recover soil functions and is relevant for further research on sustainable practices in global degradation hotspots.

Summary: This study investigates the toxicity of silver nanoparticles (AgNPs) on endogeic earthworms. The results demonstrate that high concentrations of AgNPs have negative effects on earthworm biomass and mortality, while silver sulphide does not have a discernible effect. Additionally, earthworms show a preference for soil without AgNPs or silver sulphide. These findings have important implications for the application of AgNPs in agricultural fields.
