Summary: Fertilization and soil environmental factors play a role in the niche differentiation of ammonia-oxidizing microorganisms and affect the ammonia-oxidation process. In this study, the effect of manure, chemical fertilizer, and manure combined with biochar on soil properties and the abundance, diversity, and structure of ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB) in the rhizosphere were investigated. The results showed that chemical fertilizer and manure combined with biochar increased the potential nitrification rate (PNR) and AOA amoA gene abundance, while manure combined with biochar decreased PNR and AOA amoA gene abundance. The population structure of AOA and AOB was influenced by pH, available phosphorus, carbon-to-nitrogen ratio, soil moisture content, nitrate nitrogen, and ammonium nitrogen in the rhizosphere. The ammonia oxidation process in the acid purple soil was dominated by AOA in the presence of chemical fertilizer and pig manure combined with rice husk biochar.

Summary: Brachiaria humidicola (syn. Urochloa humidicola) has been recognized for controlling soil nitrification through releasing nitrification inhibitors (NI), termed as biological nitrification inhibition (BNI), which can reduce net nitrification rates by 50 to 85%. Adjustment of soil pH and microbial background has little influence on BNI performance, while the decrease in net nitrification rates mainly depends on microbial N immobilization and efficient plant N uptake.

Summary: This study found significant shifts in potential ammonia oxidation rates (PARs) and gene abundances of ammonia-oxidizing bacteria (AOB) and ammonia-oxidizing archaea (AOA) along different salinity gradients. The PARs were higher under high salinity conditions, and the AOB gene abundance was greater than AOA under moderate and high salinity. This has important implications for nitrogen cycling in estuarine sediments.

Summary: This study investigated the emission characteristics and relative contributions of ammonia-oxidizing archaea (AOA) and bacteria (AOB) and other microbial processes to nitrous oxide (N2O) production in greenhouse vegetable fields in the middle and lower reaches of the Yangtze River. The results showed that the ammonia oxidation process is the dominant contributor to N2O production, regardless of soil pH. AOA-driven N2O emission rates were consistently higher than AOB-driven rates, and both were positively correlated with soil pH.

Summary: An aerobic N-15 microcosmic experiment was conducted to compare the inhibitory effects of the biological nitrification inhibitor (BNI), methyl 3-(4-hydroxyphenyl) propionate (MHPP) and the synthetic nitrification inhibitor 3,4-dimethylpyrazole phosphate (DMPP) on the gross nitrification rate and the abundance and community composition of ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB) in contrasting soils. The results showed that the two inhibitors had different effects on nitrification rates and the response of AOB to the inhibitors was more sensitive.

Summary: The effects of biological nitrification inhibitors on nitrogen loss and fertilizer N recovery efficiency in staple food crops are not well understood. This study investigated the effects of the biological nitrification inhibitor MHPP and/or urease inhibitor NBPT on NH3 volatilization, N leaching, and fertilizer N recovery efficiency in rice growth experiments. The results showed that the fertilizer N recovery efficiency significantly increased in the MHPP and NBPT+MHPP groups in calcareous soil, and the rice yield increased in the NBPT+MHPP treatment. However, these effects were not significant in acidic soil. MHPP had a significant effect on soil ammonia oxidizers, with the response depending on the soil type.

Summary: The study used high throughput sequencing, real-time quantitative PCR, and allylthiourea to differentiate between the contributions of ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB) to ammonia oxidation. Results showed that AOB were the major contributors to ammonia oxidation, with Nitrosomonas being the predominant genus. Aeration favored AOB ammonia oxidation, while Ca(NO3)(2) injection increased AOA contribution and influenced the growth of ammonia oxidizers.

Summary: Anthropogenically-driven climate change has impacted the growth of phytoplankton in global lake systems, leading to widening differences in waterbody gross primary productivity (WGPP). Median WGPP in global inland lake systems has significantly decreased, with high control by chrysophytes in high-latitudinal regions and dominance by diatoms, cyanobacteria, and chlorophytes in low-latitudinal regions. The contribution of dominant and sub-dominant phytoplankton communities is crucial to WGPP. Regulating environmental conditions to promote phytoplankton community diversity and competition is important for maintaining ecological balance, environmental health, and the carbon cycle in global lake systems.

Summary: This study proposes a Natural Language Understanding-Based Deep Clustering (NLU-DC) approach for global meta-analysis of lake topics. By analyzing a large literature dataset, it is found that lake topics have become more abundant and concentrated towards central ones over the century. Six evolution patterns are identified, and it is observed that emerging topics in the past twenty years attract less attention while the dependency between topics is receiving more attention.

Summary: This study developed a new modeling framework called Process-guided Hybrid BBNs (PH-BBNs) to bridge the gap between Process-based Watershed Models (PWMs) and uncertainty-based BMP planning. The findings suggest that PH-BBNs can effectively capture the critical pathways of water, sediment, and Total Phosphorus (TP) loss, and highlight the vulnerability of watersheds to climate change. The implementation of parallel terraces and filter strips is recommended for reducing TP loads with high compliance confidence.

Summary: Eutrophication is a global challenge, and Lake Dianchi in China is an example of the difficulty in restoring a highly eutrophic freshwater lake. By using a probabilistic water quality model, it is found that a minimum 50% reduction in pollution load is required to maintain the current water quality state in Lake Dianchi. To improve water quality, at least a 60% reduction in nutrient load is needed. However, the system stabilizes quickly after about 10 years, which may explain the limited results from previous restoration efforts.

Summary: Balancing clean water and economic growth remains a challenge for achieving the Sustainable Development Goals (SDGs) set by the United Nations. This study proposes a new watershed management framework (WAM-SDGs) that integrates water quality impacts and cost-effectiveness analysis of catchment actions. The method was tested in two catchments in China, showing improved cost-effectiveness and reliability compared to traditional methods. Priority should be given to urban catchments for water quality improvement, while agricultural catchments are more cost-effective.

Summary: China has made significant efforts in controlling industrial pollution, but the synergistic effects among different industrial sectors and their changes with environmental policies remain unclear. This study addressed this knowledge gap by compiling a dataset called WatSim-CIEPE, which includes 1.28 million individual enterprise data. The findings showed a power function decreasing trend for emission per unit output value, with synergistic effects of load reduction at different stages and earlier inflection points in coastal cities. The spatial evolution of pollutant emission and gross industrial output value (GIOV) exhibited completely opposite patterns due to the migration of chemical and metal sectors to western China. The time gap between national development strategy implementation and the break-point of GIOV gravity center variation implies a hysteresis effect of development policies. Three risks in China's industrial pollution control were identified: (a) increasing NH pollution in western regions, (b) potential dominance of the food sector as a pollution source, and (c) further aggravation of the imbalance between industrial development and pollution control.

Summary: Human activities and climate change are posing threats to the water quality of rivers in China. By using stacking machine-learning models, we simulated the monthly concentrations of various pollutants in the nation's major river basins from 1980 to 2050 based on a 16-year monitoring dataset. The results showed significant improvement in water quality, except for the concentration of total nitrogen (TN), which may be attributed to the lack of control targets and assessment systems for TN. Anthropogenic factors were found to play a bigger role than climatic and geographical drivers in determining the concentrations of TN, total phosphorus (TP), and ammonia-nitrogen (NH3-N).

Summary: Negative-emission technologies, including bioenergy with carbon capture and storage, may hinder land-based Sustainable Development Goals while being necessary for China's carbon neutrality. A scenario analysis reveals the potential impacts of bioenergy deployment in China and how measures like free trade and food system efficiency can mitigate sustainability concerns. Modelling shows that domestic bioenergy production with food self-sufficiency restrictions could decrease China's calorie intake and increase food prices, while removal of these restrictions or implementing measures like reducing food loss and waste and narrowing crop yield gaps can effectively mitigate these impacts.
