“…Education can improve farmers' application of technology and improve productivity, which is consistent with the research of M. Reimers, Wu Y., and others [51,52]. Through education and training, farmers have improved their production skills and awareness of environmental protection, thus improving the efficiency of input factors and reducing the use of polluting production factors such as chemical fertilizers and pesticides, which is conducive to improving AEE [22,26]. The difference is that both HHC and MHC also have a significant promotional effect on AEE.…”

“…By educating and training farmers, their production ideas, knowledge and skills, and awareness of environmental protection will be affected, which will change their production decisions and further affect AEE. On the one hand, farmers can not only effectively improve the efficiency of technology use but also enhance their ability to absorb new technologies and knowledge by receiving vocational education and technical training [22]. This has also been proven in other regions.…”

Agricultural ecological efficiency (AEE) is an important index to measure the coordinated development of agricultural production, resources, and the environment. This study tries to explore the impact of rural human capital (RHC) on AEE, hoping to provide a reference for promoting the green development of agriculture. Data sets (2006–2021) used in this study were gathered from Official Statistics Panel data in 30 provinces in China. Firstly, the super-efficient slacks-based measure model (SBM) with non-expected output is employed to effectively measure AEE. Secondly, the entropy method is used to measure RHC in three dimensions: education, health, and migration. Finally, this study discusses the impact of RHC on AEE using the panel Tobit model and further verifies the moderating effect of Internet popularization on the effect of RHC on AEE using the moderating effect model. The results show that RHC has a significant positive impact on the promotion of AEE, and this positive impact has obvious regional heterogeneity. Specifically, RHC has a greater promoting role on AEE in the eastern and northeastern regions, while it has a smaller promoting role on AEE in the central and western regions. In addition, Internet penetration plays a positive moderating role in the mechanism of the effect of RHC on the AEE. This study may serve as a reference for improving AEE by providing theoretical guidance and policy suggestions for promoting agricultural green development.

“…Government policies can have a significant impact on multi-crop N fertilizer management in agriculture. Comparing the data on agricultural fertilizer use in Hubei Province for the last 10 years [46], we found that the implementation of the zero growth in fertilizer use policy effectively reduced the amount of fertilizer applied and reduced fertilizer nonpoint source pollution and carbon emissions, which improved the ecological efficiency of food production [47]. This phenomenon indicates that the policy also played a role in the reduction in N fertilizer application.…”

Quantifying potential reductions in environmental impacts for multi-crop agricultural production is important for the development of environmentally friendly agricultural systems. To analyze the spatial differences in the potential reduction in nitrogen (N) use, we provided a framework that comprehensively assesses the potential of improving N use efficiency (NUE) and mitigating environmental impacts in Hubei Province, China, for multiple crops including rice, wheat, maize, tea, fruits, and vegetables, by considering N and its environmental indicators. This framework considers various sources such as organic N fertilizers and synthetic fertilizers, along with their respective environmental indicators. We designed different scenarios assuming varying degrees of improvement in the NUE for cities with a low NUE. By calculating the N rate, N surplus, N leaching, and greenhouse gas (GHG) emissions under different scenarios, we quantified the environmental mitigation potential of each crop during the production process. The results showed that when the NUE of each crop reached the average level in Hubei Province, the improvement in environmental emissions is favorable compared to other scenarios. The N rate, N surplus, N leaching, and GHG emissions of grain (cash) crops could be reduced by 25.87% (41.26%), 36.07% (38.90%), 49.47% (36.14%), and 51.52% (41.67%), respectively. Overall, improving the NUE in cash crops will result in a greater proportionate reduction in environmental impacts than that in grain crops, but grain crops will reduce the total amount of GHG emissions. Our method provides a robust measure to assess the reduction potential of N pollution and GHG emissions in multi-crop production systems.

“…Correspondingly, China is the world's largest producer and consumer of fertilizers [2]. Fertilizer application in China is 328.5 kg per hectare, far exceeding the global average of 120 kg per hectare [3]. This excessive use of fertilizer has resulted in various non-point source pollution issues, such as soil compaction [4], the eutrophication of water bodies [5], and heavy metal contamination of the soil [6].…”

The overuse of fertilizers has caused significant environmental pollution. In this paper, we aim to improve fertilizer utilization and promote sustainable agricultural development. Based on panel data at the flag (county) level in Inner Mongolia from 2001 to 2020, we analyzed the spatial heterogeneity and correlation of fertilizer application intensity using a two-stage nested Theil index and Moran’s I, and employed a Durbin model to elucidate its spatial spillover effects. The results show that overall disparities in fertilizer application intensity showed a decreasing trend, with league (city) disparities being the main reason for the overall disparities. In terms of spatial patterns, there is a positive spatial correlation between flags (counties), with the western region exhibiting a “high-high” type that gradually shifts towards the eastern region, particularly the cities of Tongliao and Chifeng. The central and eastern regions exhibit a “low-low” type. Future endeavors to decrease fertilizer application intensity are mainly focused on establishing “high-high” clusters. Policymakers should leverage these spatial interactions to diminish fertilizer usage and mitigate environmental pollution. Farmers, affluence, agricultural economic development, and grain yield positively influence fertilizer application intensity while agricultural modernization and land size have negative effects. All these factors demonstrate significant spatial spillover effects.
