Summary: Nitrogen fertilization is the main source of nitrous oxide (N2O) emissions in agricultural soils, but the reasons for the varied response of N2O emissions to N fertilizer are not clear. This study investigated the effects of ammonium-based fertilizers and nitrification inhibitors on N2O emissions in upland agricultural soils in northern China. The results showed that the variations in N2O emissions were strongly correlated with soil nitrite dynamics, and that alkaline soils had higher ammonia oxidation potential and higher N2O emissions.

Summary: This study conducted a field trial to investigate the impact of biochar-based fertilizer on soil N2O emissions in a subtropical Moso bamboo plantation. The results showed that biochar decreased N2O emissions by lowering WSON concentration and N-cycling enzyme activity in soils. These findings suggest that biochar application could be an effective strategy for mitigating N2O emissions in subtropical plantation soils.

Summary: Through a 20-year chronosequence study of perennial ramie cropping, it was found that the soil carbon sequestration rate increased over time due to the accumulation of organic carbon in the topsoil, particularly in the 20-40 cm soil layer. Ramie cropping led to a significant increase in organic input of residues and fine roots, enhancing soil nitrogen nutrition and microbial catabolic functions.

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: The introduction of cover crops in winter shows positive effects on rice yield, soil quality, and gaseous emissions, but may increase methane and nitrous oxide emissions. Considering the balance between environmental concerns and productivity, Chinese milk vetch-rice with cover crop residue return is the most practical and sustainable choice.

Summary: Cover crops play a crucial role in increasing soil fertility and mitigating climate change through nutrient recycling and organic matter buildup. A study on the short-term effects of incorporating winter vetch into a cover crop mixture found that higher soil fertility led to a significant reduction in relative net phyllo- and rhizodeposition, despite an increase in cover crop biomass. Adjusting for unrecovered root fragments significantly reduced the estimated phyllo- and rhizodeposition, highlighting that many previous estimates may have been overestimated. Autumn cover crop usage provides a key opportunity for carbon storage, with both aboveground biomass input and belowground carbon investment being important factors.

Summary: This study examined the effects of biochar-based fertilizer treatment on soil greenhouse gas emissions in a bamboo plantation. The results showed that biochar-based fertilizer treatment reduced soil nitrous oxide emissions, while chemical fertilizer and mixed fertilizer treatments increased emissions. Additionally, biochar-based fertilizer treatment and mixed fertilizer treatment increased soil methane uptake, while chemical fertilizer treatment had no significant effect. The study also found that different treatments affected greenhouse gas emissions by changing soil carbon and nitrogen pools.

Summary: In this study, an on-farm field experiment was conducted in northeastern Thailand to investigate the effects of different eucalyptus biochar (BC) application rates on upland rice and sugarcane crops. The results showed that the BC2 treatment decreased soil mineral nitrogen content during the upland rice period but increased it during the sugarcane period. Additionally, the BC2 treatment significantly reduced methane and nitrous oxide emissions during the upland rice period.

Summary: The study found that increasing soil pH has significant effects on reducing N2O emissions and lowering N2O emissions from denitrification and heterotrophic nitrification. Different acid-neutralizing materials, such as quicklime and pig manure, have varying effects on N2O emissions in acidic soils. Therefore, careful consideration of pH-raising substrates is needed to avoid adverse effects when implementing pH amelioration practices.

Summary: This study applied various footprinting approaches to comprehensively evaluate the environmental impacts and economic benefits of organic rice farming and conventional rice farming. The results showed that organic rice farming can mitigate greenhouse gas emissions, but has a lower yield compared to conventional rice farming. Despite the lower yield, organic rice farming has a higher economic return.

Summary: Simulation of future climate changes in the Ishikari River basin in Hokkaido, Japan was conducted using global climate models. The selected models showed a significant correlation with temperature measurements but did not accurately represent precipitation features. The findings suggest that the northern part of the basin is more likely to become hotter with heavier precipitation in the future.

The EU Common Agricultural Policy (CAP) includes nature conservation programs to promote sustainable agriculture, but farmers face barriers such as lack of information and complicated procedures. NatApp is a digital tool that can assist farmers in choosing, applying, implementing, and documenting nature conservation measures, providing unique features compared to other digital farming tools.

Summary: The study investigated soil properties and soil erodibility after fire in rotational shifting cultivation (RSC) practiced by hill tribes in Thailand. The results showed that soil nutrients and erodibility increased after burning and remained higher than pre-burning levels for at least 2 years. The levels of soil organic carbon and total nitrogen decreased after burning, and their recovery varied among different fallow fields.

Summary: Fodder maize cultivation under low mountain conditions in Central Europe is challenging for organic dairy farmers due to low temperatures and high precipitation values in spring, which delay the growth of maize and result in lower and fluctuating yields. A comparative experiment in Germany showed that ridge-row cultivation of maize significantly increased soil temperature, positively impacted plant development and starch content, and resulted in higher dry matter yield and protein yield compared to flat surface cultivation.

Summary: This study aims to estimate the spatiotemporal variation in water runoff and soil loss in the Tokoro River watershed in Hokkaido, Japan. Simulation results showed that croplands, especially sloped croplands, were the primary source of stream sediment load. Soil loss mainly occurred in early spring and late summer, and surface runoff when the soil was frozen was considered an important driver of soil loss.

Summary: This study aims to investigate the impact of fire on soil properties and soil surface loss in rotational shifting cultivation, finding that older fallow fields tend to accumulate more soil organic carbon and soil organic nitrogen. The combustion of organic matter during the fire releases soil nutrients, leading to an increase in soil nutrients. The highest soil surface loss was observed 9 months after the fire on the upper slope. Slope also has a significant impact on soil properties.

Summary: The addition of 2% biochar significantly enhances the growth of purslane and increases soil microbial activity. It also alters the abundance of P-cycling-related bacteria and increases the concentrations of nitrogen, phosphorus, and carbon in the soil. These findings suggest that biochar has potential for improving the reclamation of degraded saline soil.

Summary: Successful conservation efforts have led to the recovery of large mammals in central Europe. However, the return of these species is controversial and can lead to conflicts. Involving the public in monitoring and managing wildlife can be effective in mitigating these conflicts. A survey conducted in wildlife parks in Germany found that visitors had high knowledge of wolves but lower knowledge of bison and moose. Exposure to the species and demographic variables influenced visitors' knowledge. Younger participants and those with higher knowledge were more willing to participate in citizen science activities. These findings provide insights for effectively recruiting citizen scientists for wildlife conservation.
