Summary: Major changes in China's agricultural factor input structure have affected fertilizer input. Both capital and labor input have a positive correlation with chemical fertilizer input, while factor substitution elasticity plays a negative moderating role. The increase in capital input and its substitution for labor are the main drivers of fertilizer input increase.

Summary: The cultivation of energy crops aims to produce renewable energy, substitute fossil resources, and make a substantial contribution to energy supply. Maize is the most commonly grown energy crop in Germany due to its high energy yields, but the debate over its impact on agro-ecosystems raises the question of alternative energy crops. Research shows that while some combinations of crops may have higher yields than maize, maize remains the most efficient energy crop in terms of energy output compared to energy input.

Summary: Small Island Developing States (SIDS) are highly vulnerable to marine litter and plastic waste pollution, but often lack the infrastructure for waste treatment. This research focuses on quantifying the plastic footprint of Seychelles using an Environmentally-Extended Input-Output Analysis (EEIOA) and multi-regional input-output (MRIO) approach. The study finds that SIDS may have the same level of plastic use and waste per capita as high-income countries, emphasizing the need for joint actions to reduce plastic pollution in these regions.

Summary: The evolution of resistance in winter wild oat is mainly attributed to the Ile-2041-Asn mutation, resulting in seeds with high adaptability and germination capabilities. There were no significant differences in germination responses between resistant and susceptible seeds under various environmental conditions, indicating a lack of fitness cost at the seed level. This suggests that controlling resistant winter wild oats is more challenging due to the absence of fitness cost, emphasizing the need for crop and herbicide rotation to delay further resistance evolution.

Summary: Healthy agroecosystems are essential for providing ecosystem services, but the lack of information regarding their health degree leads to their unsustainability. To assess the health status of agroecosystems, a spatial analysis-based model was developed using GIS media, surveyed data, and field monitoring. The study found that factors such as proper tillage methods, appropriate weed control, optimal consumption of high-quality pesticides, high soil organic matter, and yield above 2.6 ton ha(-1) were key contributors to the health of agroecosystems. In contrast, low-quality pesticide use, inappropriate tillage tools and machinery, insufficient knowledge of farmers regarding pesticide and fertilizer usage, and weed resistance to herbicides were identified as the main reasons for non-health status in surveyed barley agroecosystems.

Summary: This paper proposes a grey box model for fuel consumption prediction of wing-diesel hybrid vessels based on feature construction. By using both parallel and series grey box modeling methods and six machine learning algorithms, twelve combinations of prediction models are established. A feature construction method based on the aerodynamic performance of the wing and the energy relationship of the hybrid system is introduced. The best combination is obtained by considering the root mean square error, and it shows improved accuracy compared to the white box model. The proposed grey box model can accurately predict the daily fuel consumption of wing-diesel hybrid vessels, contributing to operational optimization and the greenization and decarbonization of the shipping industry.
