Summary: Legume-based cropping systems have the potential to reduce nitrous oxide emissions in Mediterranean agroecosystems, but may not always be effective in dry years. Efficient supplementary nitrogen fertilization may be necessary to achieve reduced greenhouse gas emissions without compromising crop yields.

Summary: The study found that diverse crop rotations including canola and legume crops have the potential to store more soil organic carbon (SOC) than traditional wheat-based cropping systems in semi-arid prairies of Canada. When coupled with no-tillage (NT) and residue management, these diverse rotations can enhance crop yields and maximize SOC sequestration.

Summary: This study evaluated the ability of the DNDC model to estimate soil parameters, crop yield, and N2O emissions in long-term multi-cropping systems in Hebei, China. The model effectively simulated most of the parameters, but had some errors in estimating peak values. The results showed that optimized and alternative cropping systems reduced nitrogen fertilizer use, increased grain yield, and decreased N2O emissions compared to conventional systems.

Summary: The study evaluated the effects of nitrogen application timing and cereal rye cover crops on soil N2O emissions, finding that the combination of in-season nitrogen application with cover crop decomposition can increase N2O emissions, but the cumulative effects vary across years.

Summary: Manual sampling of N2O soil fluxes can be labor-intensive and often fails to capture daily variations accurately. This study in a highly fertilized corn system in Wisconsin analyzes N2O soil emissions over 3 years, finding that diurnal fluctuations impact emission estimates and high-emission periods contribute significantly to cumulative emissions. High temporal resolution measurements are needed to accurately estimate cumulative emissions, especially during peak emission events.

Summary: In this study, a long-term experiment was conducted in the North China Plain to evaluate different farming management practices in response to climate change. The results suggest that conservation agriculture practices, specifically no-tillage method combined with low nitrogen fertilizer and high straw addition, can enhance crop yields, increase soil organic carbon, and mitigate greenhouse gas emissions for sustainable agricultural production under future climate change scenarios.

Summary: This study evaluated the effects of different winter cover crop mixtures on CO2 and N2O emissions and soil properties, and found that cover crop treatments could increase cash crop yield and decrease N2O emissions, but had no significant effect on net greenhouse gas balance, yield-scaled emissions, and greenhouse gas intensity. Integrating cover crops into agricultural ecosystems may be a climate smart strategy for forage production.

Summary: Developing and implementing improved management practices are necessary to enhance the sustainability of organic cropping systems. This study examined the effects of different organic cropping systems on soil greenhouse gas emissions and crop yields. The results showed that the combination of chisel plough and fall-seeded green manure minimized nitrous oxide emissions without increasing yield-scaled emissions. However, a long-term assessment is still needed due to the short duration of the study and the recent conversion from conventional agriculture.

Summary: This study evaluates the global climate sensitivity of caloric yields and cropping frequency (CF). The results show a negative association between warming and both caloric yield and CF. By the 2050s, projected CF increases in cold regions will be offset by larger decreases in warm regions, resulting in a net global CF reduction. This study highlights the negative impact of warming on cropping frequency and caloric yield globally.

Summary: The study found that the Chinese milk vetch-rice-sweet potato parallel to soybean cropping system significantly reduces CH4 emissions but increases N2O emissions. Paddy-upland rotation decreases soil CH4 emissions but increases N2O emissions. The interaction between Chinese milk vetch incorporation and paddy-upland rotation enhances N2O emissions and soil nitrate content.

Summary: Crop rotation is a management practice with high greenhouse gas mitigating potential. Three long-term rotation studies in Wisconsin were selected to evaluate the temporal and spatial variability of N2O, CO2, and CH4 emissions. Results showed that 2-year corn-soybean rotation (CS) or 3-year corn-soybean-wheat rotation (CSW) can be equally effective in reducing N2O emissions compared to continuous corn (CC).

Summary: Row croppers in the Southeast United States are interested in diversifying their cropping systems and increasing revenue by growing a winter cash crop between summer crops, especially cotton and peanut. Double-cropping carinata between summer crops has potential to boost grower revenue and increase land use efficiency in the region. Research was conducted to quantify the effects of summer cropping history on the performance of carinata as part of diversified crop rotations in the SE US.

Summary: NO2 emissions from wall-mounted gas stoves used for household heating have become a significant source of indoor pollution in Chinese urban areas. The high indoor concentration of NO2 poses potential health risks to residents. It is urgently necessary to establish relevant regulations and implement emission reduction technologies to reduce NO2 emissions from wall-mounted gas stoves.

Summary: This study investigates the relationship between dissolved organic matter (DOM) and Rare Earth Elements (REEs) in sediments from Yundang Lagoon, China. The results show four distinct fluorescent components, with protein-like substances being the most prevalent. Additionally, the total fluorescence intensity and LREE concentrations exhibit a synchronized increase from Outer to Inner to Songbai Lake core sediments. The findings demonstrate a strong correlation between DOM content and pollution levels.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. 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.

Summary: In this study, inverse vulcanized polysulfides (IVP) were synthesized by reacting molten sulfur with 4-vinyl benzyl chloride, and then functionalized using N-methyl D-glucamine (NMDG). The functionalized IVP showed a high mercury adsorption capacity and a machine learning model was developed to predict the amount of mercury removed. Furthermore, the functionalized IVP can be regenerated and reused, providing a sustainable and cost-effective adsorbent.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
