Summary: In crop production systems, the use of high rates of fertilizer application leads to significant losses of nitrogen (N) and phosphorus (P) to the environment, causing air pollution and water body eutrophication. Quantifying daily N and P losses and their drivers in rice-rapeseed growing systems revealed significant trade-off relationships between daily uptake and surplus for N and P during the entire growing stages. Water input and leaching loss were found to contribute most to N and P loss in rice and rapeseed systems.

Summary: Ammonia concentrations in Europe have not shown significant decreases despite management efforts, as indicated by a study in Switzerland and Liechtenstein. Trends analysis showed that 91% of the sites experienced no change or increasing NH3 concentrations. This conflicts with the reduction in NH3 emissions reported in the Swiss emission inventory.

Summary: This study quantified annual changes in nitrogen and phosphorus river loads and nutrient balances at the Mississippi River outlet. It was found that the river load response to watershed nutrient balances shifted between 1975 and 2017. The impacts of legacy nutrients and other latent factors on river nutrient load trends were evaluated, showing the potential importance of factors such as best management practices and changes in watershed buffering capacity.

Summary: The aim of this study was to investigate the changes in macrophyte community along the Izica River over time. The researchers surveyed the distribution and abundance of macrophyte species in 1996, 2000, and 2016, and calculated the River Macrophyte Index (RMI) to assess the ecological status of the river. The results showed significant changes in the species composition of the macrophyte community over the years, which could be attributed to environmental factors and human activities.

Summary: Global agricultural ammonia emissions have increased significantly in the past four decades, with cropland and livestock emissions playing a major role. Wheat, maize, rice, cattle, chicken, goats, and pigs are identified as the main contributors to ammonia emissions. The lack of regulations on ammonia emissions has led to increased reduced nitrogen deposition, particularly in hotspot regions such as China, India, and the United States, where nitrogen overuse is prevalent. Reducing agricultural ammonia emissions is crucial for future efforts to reduce nitrogen deposition.

Summary: The use of synthetic nitrogen fertilizers in Spanish agriculture has led to significant increases in GHG emissions, particularly in the Mediterranean region. The doubling of direct N2O EFs was driven by the expansion of irrigation, synthetic fertilizers, and liquid manure. Despite large energy efficiency gains in industrial fertilizer production, these benefits were offset by changes in the fertilizer mix and a tenfold increase in downstream N2O emissions.

Summary: The study aimed to investigate the effects of continued use of a blend of biodiesel and petroleum diesel fuel on engine performances and exhaust gas emissions. Results showed a decrease in maximum engine power, an increase in specific fuel consumption and CO emission, and a reduction in CO2 emission after 1000 hours of operation. The worsened engine performance was likely caused by deposits on the injector tip due to thermal oxidation of unsaturated fatty acids in the biodiesel raw material. Statistical analysis indicated significant changes in the obtained data.

Summary: Water quality challenges related to non-point source pollution persist in agricultural landscapes, despite previous efforts by farmers and landowners. Future climate projections will introduce new challenges to landscape hydrology and its impact on water quality. This study investigated nutrient trends and mitigation measures in different catchments with varying agro-climatic and environmental conditions.

Summary: Phosphorus usage in agriculture is important but excessive use can lead to wastage of resources and soil surplus. Asian countries, particularly in urbanized coastal areas, have higher levels of agronomic soil phosphorus surplus than the global average. Anthropogenic factors, such as population growth and increased fertilizer usage, have greatly contributed to phosphorus loading and soil surplus. However, efforts in wastewater treatment and reduction in agricultural land have helped improve the environmental situation since the 1980s. Factors such as soil properties, fertilizer usage, precipitation events, and crop types all affect soil phosphorus balance. It is important to consider the non-point source loss due to precipitation to avoid overestimating soil phosphorus surplus.

Summary: The erosion, deposition, and transport processes of sediment in the Yellow River Basin have been significantly impacted by climate changes and human activities, leading to a decreasing trend in sediment loads. Human activities have played a dominant role in explaining the reduction trend of sediment loads, while precipitation and temperature are the predominant meteorological factors affecting sediment variations. This study provides important insights for the ecological restoration and sediment management of the Yellow River Basin.

Summary: The study found that long-term application of pig manure+urea can increase corn yield, but compared to adding pig manure+superphosphate, the Olsen-P content is lower. Adding pig manure can increase P compounds related to microbial processes, while adding synthetic fertilisers can promote the accumulation of IHP.

Summary: The optimization of nitrogen (N) fertilization is crucial for achieving high crop yields and high N use efficiency (NUE) with low environmental risks. This study conducted long-term observations in the North China Plain, and found that stable high wheat yield could not be achieved without sufficient N inputs. The optimal N application for high yield, NUE, and low environmental risks was determined to be 180 kg N ha-1 based on the findings.

Summary: Biochars have the potential to provide agricultural and environmental benefits, but their long-term effects in boreal regions are still unknown. This study collected data from Finnish field experiments and found that biochars can increase crop yield, reduce greenhouse gas emissions, and have implications for nitrogen fertilizer management.

Summary: Optimized fertilization is an effective strategy for improving nitrogen use efficiency and maintaining high crop yield. This study investigated the long-term impacts of different nitrogen rates on maize yields and soil nitrogen and carbon dynamics. The results showed that the optimum nitrogen rate and combined organic-inorganic nitrogen rate can achieve similar yields as the farmers' nitrogen rate. Furthermore, substituting 20-30% manure for inorganic fertilizer under the optimum nitrogen rate could help reduce soil nitrogen losses and increase soil organic carbon stock for sustainable agriculture.

Summary: The biota of European rivers are influenced by a variety of stressors, with alterations in hydro-morphology, nutrient enrichment, and toxic substances being the most significant factors. The interaction between these stressors plays a crucial role in influencing the ecological status of the rivers. This highlights the importance of implementing comprehensive management strategies at the catchment scale to achieve good ecological status in European surface waters.
