Summary: This research aimed to investigate the effects of crop diversification on N2O emissions in the irrigation systems of the Ebro valley. The results showed that double-cropping with legumes and maize could reduce N fertilizer use and mitigate N2O emissions. Additionally, adopting a no-tillage system combined with medium N fertilization rates in the double-cropping mode could effectively reduce both soil N2O emissions and improve crop yields.

Summary: No-tillage management significantly decreased CH4 emissions in paddy fields, but showed a slight non-significant tendency to increase emissions in maize-cultivated fields. Factors like climate, soil, and years since conversion to NT management had weak regulation on CH4 emissions, with a slight reduction tendency in humid subtropical climate. Climate effects were often confounded by crop choice and should be interpreted cautiously.

Summary: Understanding the nitrogen transformations in soil with different tillage practices is crucial for efficient nitrogen use and environmental protection. This study found that application of wheat straw significantly increased organic nitrogen content in soil and promoted fast nitrogen mineralization. Under long-term no-tillage conditions, the straw N remained mainly in the particulate organic matter nitrogen pool, providing a theoretical basis for improving straw N use efficiency.

Summary: The emission of nitrous oxide (N2O) is a major challenge in modern agriculture and is significantly contributing to global warming. This study analyzed the effects of different soil managements, crop rotations, and edaphoclimatic factors on N2O emissions in the Cerrado biome. The results showed that conventional management and no alternating crop sequences intensify soil N2O emissions.

Summary: The interaction mechanism between CO, CO2, and NO gas molecules and Pt-n-SnS2 (n = 1-3) and Pt-n-MoTe2 (n = 1-3) is analyzed using density functional theory calculations. While Pt-2-SnS2 and Pt-3-SnS2 are unsuitable for the detection and adsorption of CO2 and the three gases, Pt-SnS2 exhibits almost unchanged conductivity after CO adsorption. Pt-doped MoTe2 substrates show enhanced adsorption capacity for the target gases, except for Pt-2-MoTe2 and Pt-3-MoTe2 which undergo significant deformation upon NO adsorption and weak interaction with CO2. This study provides a theoretical basis for developing gas sensors for automotive and industrial emission gases.

Summary: This study reports on three years of turbulent CO2 fluxes measured above Vienna using an eddy covariance system. The study found that the seasonal variation of CO2 fluxes was influenced by temperature and wind direction, as well as the urbanization level of the area. The weekday-weekend patterns of CO2 fluxes correlated with local traffic counts, but the correlation was weaker on weekends and public holidays. Vegetation fluxes also influenced CO2 fluxes during certain periods, indicating a partial decoupling between turbulent exchange and surface fluxes. The study provides evidence that accurate estimates of urban CO2 fluxes can be obtained using tall tower eddy covariance.

Summary: Understanding the roles of natural drivers and anthropogenic activities in greenhouse gas emissions of arable fields is crucial for adopting appropriate agricultural management practices. This study found that the impact of mouldboard ploughing and no-tillage on CO2 emissions did not differ significantly over a full year, but varied in different sub-periods. No-tillage had a higher impact on both CO2 and N2O emissions compared to mouldboard ploughing.

Summary: Understanding the impact of soil management choices on yield stability is crucial for agricultural resiliency in the face of global temperature increases and regional climate changes. Long-term studies are needed to assess the potential benefits of no-till and conservation tillage, as their effects on crop yields vary depending on the crop and location. Findings from a 28-year tillage study in the southeastern U.S. piedmont region suggest that surface residue management may be more important than overall soil health in determining system performance.

Summary: This study assessed the power-energy requirements and soil tillage quality parameters of conventional and conservation implements for preparing an optimal seedbed for wheat planting. Field tests on flat, silty-clay soil using instrumented tractors showed significant differences in operative performances between the two types of machines powered by the tractor's PTO, with rotary tillers exhibiting higher fuel consumption and power requirements. However, a decrease in these parameters was observed when transitioning from conventional to more conservation tillage implements, with rotary tillers providing a better quality seedbed.

Summary: The study aimed to understand the differences in grain protein content of 706 rice accessions in different regions and rice subtypes. The influencing factors of grain protein content differences were analyzed from the perspectives of genetic characteristics, environment, rice subtypes, and breeding process. The results showed that the grain protein content of indica rice in most countries and regions was higher than that of japonica rice. From the perspective of the rice breeding process, the protein content of modern varieties in japonica was lower than that of landrace varieties. In most countries, modern varieties of indica rice had higher protein content than landrace varieties did.

Summary: Nitrogen fertilizer application affects the structure of rice protein and starch, reducing the eating quality of rice during cooking. High nitrogen fertilizer increases protein content, inhibiting starch gelatinization. Additionally, rice protein with high nitrogen fertilizer has more beta-sheets, slowing water entry into starch molecules and preventing short-range ordered structure destruction.

Summary: The taste quality of rice is a crucial factor affecting its marketing and distribution, as rice with high taste quality is more favored by consumers and commands a higher price. Accurate and rapid determination of rice protein content plays a vital role in assessing taste quality and facilitating marketing. In this study, NIR spectra combined with partial least squares regression (PLSR) were utilized to model protein content in 84 rice samples, while different selection algorithms (CARS, MC-UVE, RF) based on key wavelengths were employed to evaluate the accuracy of NIR spectra in predicting rice protein content. The results demonstrated that the CARS algorithm achieved excellent performance in predicting rice protein content.

Summary: Integrated rice-crayfish farming system (RCS) is popular in China, but the impact of trench on greenhouse gas (GHG) emissions has been ignored. This study compared GHG emissions between rice monoculture (RM) and RCS, finding that RCS had lower CH4 emissions due to lower mcrA abundance and higher pmoA abundance. However, the trench resulted in higher CH4 emissions and lower N2O emissions compared to the RCS field. Overall, RCS does not mitigate global warming potential (GWP) compared to RM, unless the area ratio of the trench to the system is controlled below 13.9%.

Summary: Climate warming during the reproductive stage has a significant impact on rice quality, leading to increased chalkiness and protein content and reduced eating and cooking quality. This study evaluated the response of rice starch properties to high temperature and found that high seasonal temperature (HST) negatively affected rice quality by altering starch structure, total starch and protein content. These factors accounted for the variations in pasting properties, taste value, and grain chalkiness degree. Therefore, it is important to improve rice resistance to high temperature during the reproductive stage to enhance rice starch structure.

The results showed a decrease in NO2 concentrations, especially in urban and high-traffic areas. However, socially vulnerable populations still experienced higher levels of NO2 exposure. The study suggests that reducing NO2 disparities, particularly racial inequity, can be achieved through continued regulatory actions targeting traffic-related NOx emissions.

Summary: This study investigates the chemical composition and oxidative potential of PM10 particles in the Po Valley, Italy, and demonstrates the impact of high levels of atmosphere ammonia. The rural area had significantly higher ammonia concentrations compared to the urban site, resulting in higher levels of secondary inorganic aerosol. Although the SIA components did not contribute significantly to the PM10 oxidative reactivity, they were correlated with the oxidative potential measurements. This suggests that the contribution of SIA to PM oxidative toxicity cannot be ignored.
