Summary: This study provides scientific evidence for the rational use of crop straw to replace chemical potassium inputs. Long-term field experiments showed that integrating straw return with potassium fertilization improved soil potassium supply and balance, increasing exchangeable and non-exchangeable potassium content in the soil and preventing depletion of non-exchangeable potassium pool under intensive cropping. Additionally, straw return contributed to higher soil available potassium, slow available potassium, and sustained potassium supplying ability of soils.

Summary: The rhizosphere microbiome is crucial for plant growth and acts as an important interface for resource exchange between plants and the soil environment. This study analyzed the variations of bacterial and fungal communities in the rhizosphere of four crop species during successive cultivation and found that specific microorganisms that benefit plant growth decreased in abundance over time, while potentially pathogenic fungi increased. The co-occurrence network analysis showed that bacterial and fungal communities under maize were more stable than those under other crops. The findings highlight the importance of indigenous soil flora in determining plant growth and suggest the potential use of critical microorganisms to control crop growth and yield.

Summary: Straw returning combined with compound fertilizer was found to enhance soil structure, carbon and nitrogen contents, and the richness of soil bacterial diversity. It increased the content of larger aggregates (> 2 mm) and decreased the content of smaller aggregates (0.053-0.25 mm). Straw returning also increased the activity of urease in soil aggregates, while decreasing the activities of phosphatase and invertase. The relative abundances of Chloroflexi and Nitrospirotain in soil aggregates also increased with straw returning.

Summary: This study investigated the effects of wheat or maize straw incorporation on bacterial and fungal communities under wheat-maize rotational farming practices. The results showed that straw returning reduced bacterial density and increased their diversity before corn planting, but had no effect on fungal diversity. However, before wheat planting, returning wheat and corn stalks increased the diversity of soil bacteria and fungi, whereas returning corn stalks reduced the diversity of fungi and other microorganisms. The study also found that straw return had different effects on the relative abundance of specific microbial taxa.

Summary: This study compared enzymatic stoichiometry, microbial necromass, and microbial community between rice-crayfish co-culture and rice monoculture systems. The results showed that after conversion to the co-culture system for about three years, the availability of ammonium nitrogen increased, leading to a decrease in relative N-acquiring enzyme production. Microbial necromass content increased approximately twofold in the co-culture system, with microbial necromass contributing up to 46.72% of soil nitrogen. The elevation in NH4+ decreased N-acquiring enzyme production, while a more effective C acquisition likely promoted microbial necromass retention and production in the co-culture system. This study highlights the modification of the N pool in the surface paddy soil by the rice-crayfish co-culture.

Summary: Biochar amendment is a promising agricultural approach to combat climate change by enhancing soil carbon sequestration. It was found that biochar addition increased soil ligninase activity targeting complex phenolic macromolecules, but suppressed cellulase activity degrading simpler polysaccharides. These shifts in enzyme activities explained variations in soil carbon sequestration in different conditions, and the ligninase:cellulase ratio correlated negatively with soil C sequestration. Short-term biochar addition reduced cellulase activity and increased soil organic C sequestration, while long-term addition enhanced ligninase activity and ligninase:cellulase ratio, resulting in a smaller increase in soil organic C sequestration. This research provides evidence for the diminished long-term soil C sequestration with biochar addition.

Summary: Adsorption of heavy metals by biochar adsorbents can be enhanced by appropriate biodegradation processes before biochar preparation. The biochar (LBC) prepared from compost collected in the later biodegradation process showed a 50% higher adsorption capacity compared to the biochar (EBC) prepared from compost collected in the early phase. LBC had more oxygen-containing functional groups, ion exchange sites, and carbonate ions, leading to a 100% improvement in adsorption capacity compared with virgin biochar (IBC).

Summary: A novel heterotrophic nitrification and aerobic denitrification (HN-AD) bacterium, identified as Pseudomonas nicosulfuronedens D1-1, was able to remove 97.24%, 97.25%, and 77.12% of 100 mg/L NH4+-N, NO3- -N, and NO2- -N, respectively, with corresponding maximum removal rates of 7.42, 8.69, and 7.15 mg & BULL;L-1 & BULL;h-1. The bioaugmentation of strain D1-1 enhanced the NO3- -N removal efficiency in a woodchip bioreactor, with an average efficiency of 93.8%. The study also found that bioaugmentation increased bacterial diversity and predicted genes for denitrification, DNRA, and ammonium oxidation, while reducing local selection and network modularity. These findings suggest that bioaugmentation with HN-AD bacteria can improve the stability of NO3- -N removal performance through functional redundancy.

Summary: Heavy metal contamination of soils is a global environmental issue threatening food security and human health. Little research has been done on the impact of elevated temperatures on the migration and distribution of heavy metals in soils. This study reveals that higher temperatures increase the solubility and transformation of copper (Cu) in soils, with proteinaceous components playing a significant role in the dissolution of Cu. The findings provide a better understanding of the fate of Cu in soils and its implications for risk assessment and remediation in the context of global warming.

Summary: Climate change and human activities have led to the gradual salinization of inland waters worldwide, impacting prokaryotic plankton communities and biogeochemical cycles. This study analyzed the prokaryotic plankton communities of 11 lakes in northwest China and found that salinity was the most important driver of beta-diversity. Under low salinity, prokaryotic plankton employed diverse halotolerant strategies, while under high salinity, only organisms with energetically favorable halotolerant strategies survived. High salinity decreased taxonomic diversity and impaired functional diversity related to substance metabolism. The study also revealed a precarious microbial network with increasing salinity.

Summary: The interactions between soil components have significant effects on the speciation, bioavailability, and transformation of heavy metals, however, these interactions have not been well considered in multi-surface models. A study was conducted to investigate the impact of mineral-organic interactions on lead (Pb) speciation and confirm the validity of the multi-surface model for Pb in soils. The results showed that metal oxides and soil organic matter were the main scavengers for Pb, and the introduction of straw promoted the activation of metal oxides, while the competition from Fe/Al/Ca ions reduced the binding of Pb by soil organic matter. Incorporating organic-Fe/Al/Ca interactions improved the accuracy of the multi-surface model for predicting Pb speciation distribution.

Summary: Agricultural ecosystems contribute significantly to atmospheric emissions of soil nitrous oxide (N2O), which exacerbate environmental pollution and contribute to global warming. Glomalin-related soil protein (GRSP) stabilizes soil aggregates and enhances soil carbon and nitrogen storage in agricultural ecosystems. Our findings showed that GRSP content increased with the increase in soil aggregate size, and potential N2O fluxes were highest in microaggregates (250-53 mu m), followed by macroaggregates (2000-250 mu m), and lowest in silt + clay (<53 mu m) fractions. The study also revealed a significant correlation between denitrifying microbial community, soil aggregate GRSP fractions, and potential N2O fluxes.
