Summary: This study investigated the performance of Fe-Mn-modified biochar for long-term soil remediation and its impact on Cd accumulation in rice plants. The results showed that the biochar effectively decreased the exchangeable Cd fraction in soil and reduced Cd bioaccumulation in rice, especially in the grain, ensuring food safety. Ferromanganese modification and application of biochar can maintain soil redox status, increase root Fe plaques, and enhance the stability of biochar, contributing to its high remediation efficiency over time.

Summary: A novel Chitosan-modified Mimosa pigra biochar (CMPBC) was found to have higher efficiency in removing hexavalent chromium (Cr(VI)) from aqueous systems compared to pristine biochar. The sorption of Cr(VI) was heavily dependent on pH, with the highest adsorption occurring at pH 3.0. The results suggest the potential use of CMPBC as an easily available, environmentally sustainable, and inexpensive sorbent for the decontamination of Cr(VI) from water.

Summary: This study evaluated the sorption/desorption behaviors of mixed chlorobenzenes on fresh and aged biochar at different heat treatment temperatures. The findings showed differences in sorption capacities and changes in the main sorption mechanism. Introduction of oxygen-containing polar moieties on aged biochar surfaces may reduce the sorption suppression of mixed chlorobenzenes. Additionally, biochar aging may lead to a decrease in desorption kinetics.

Summary: The differences in endodermal differentiation and Cd radial transport between japonica and indica subspecies of rice were characterized in this study. Japonica subspecies had earlier formation of Casparian strips and suberin lamellae, leading to higher lignin/suberin content and stronger inhibition on Cd radial transport compared to indica subspecies. The findings provide insights for genetic modification to develop rice with low Cd-accumulating ability.

Summary: Agricultural intensification driven by land-use changes has caused continuous and cumulative soil acidification throughout the global agroecosystem. This study used metagenomic analysis to investigate the microbial community composition and function associated with soil acidification in rice-wheat and rice-vegetable rotations. The results showed that the conversion to rice-vegetable rotations resulted in decreased soil pH and increased acid saturation ratios. The microbial community composition in rice-vegetable rotations was enriched in taxa exhibiting dehydrogenation functions and was more dependent on hydrogen, aluminum, and nitrate nitrogen.

Summary: Persistent microbial symbioses can offer advantages to plants in unfavorable conditions. This study focuses on the core microbiomes that consistently inhabit the rhizosphere of certain plants and explores their influence on plant growth and metal tolerance. The research reveals the existence of a conserved core rhizosphere microbiota in Cd hyperaccumulators and accumulators, and suggests that these core microorganisms play a crucial role in plant fitness and Cd accumulation. The findings provide a foundation for using root microbiomes to restore metal-disturbed soils.

Summary: This study analyzed the influencing factors of cropland soil acidification using the example of cropland in the Sichuan Basin of China. The results showed that precipitation was the main factor causing soil acidification. Additionally, soil pH decrease was primarily buffered by soil carbonates and secondarily by soil CEC, with soil carbonates becoming the main buffering agent when their content exceeded 36.76 g kg(-1). These findings emphasize the importance of formulating precipitation-based optimizing agronomic management practices to prevent or mitigate cropland soil acidification.

Summary: The impact of atmospheric deposition of cadmium (Cd) in cereal crops has raised global concerns. In this study, the effect and mechanism of rice in response to leaf Cd exposure were investigated using stable isotopes and a lignin-increased rice mutant. The results showed that enhanced lignin content effectively inhibited Cd transportation in plant tissues, leading to higher Cd tolerance and increased grain yield. These findings provide valuable insights into the molecular and physiological mechanisms of enhanced lignin regulating foliar Cd absorption and yield in rice.

Summary: This study investigated the effects of crop domestication on root functional traits and trait plasticity in response to neighboring plants. The authors found that wild barley had higher root functional traits and acid phosphatase activity, but lower root exudation of carboxylates and mycorrhizal colonization compared to domesticated barley under low P supply. Wild barley exhibited larger plasticity in root traits, while domesticated barley showed greater plasticity in root exudates and mycorrhizal colonization. The combination of wild barley and faba bean showed higher P uptake benefits under low P supply. These findings provide valuable insights for barley breeding and species selection to enhance P uptake.

Summary: In this study, the combined effects of ferromanganese modified biochar and flooded-aerobic water management on the remediation of Cd-polluted soil and its impact on rice production were investigated. The results showed that the modified biochar increased the sorption capacity of Cd and reduced the availability of Cd in soil under flooded-aerobic water management. This combination effectively decreased the Cd concentration in rice and improved the biomass and yield of rice.

Summary: This research aimed to uncover the detoxification mechanisms of rice in response to Cd stress through physiological, transcriptomic, and molecular approaches. The results showed that Cd stress inhibited rice growth, caused Cd accumulation, H2O2 production, and cell death. Transcriptomic sequencing revealed that glutathione and phenylpropanoid were the major metabolic pathways under Cd stress. Physiological studies demonstrated increased antioxidant enzyme activities, glutathione, and lignin contents under Cd stress. q-PCR results showed upregulation of genes related to lignin and glutathione biosynthesis, and downregulation of metal transporter genes in response to Cd stress. Further pot experiment confirmed the causal relationship between increased lignin and reduced Cd in rice.

Summary: Biochar is a useful method for increasing soil carbon sequestration and nitrogen supply in continuous monocropping. This study investigated the effects of different biochar placement methods on soil carbon and nitrogen. The results showed that biochar application significantly increased soil organic carbon and carbon pool management index, especially for dissolved organic carbon, readily oxidizable carbon, and microbial biomass carbon. Single biochar placement methods had different impacts on soil carbon and nitrogen contents, depending on the depth of placement. Overall, biochar application improved soil carbon and nitrogen pools and inorganic nitrogen supply through nitrogen remobilization.

By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.
