“…This result is consistent with Chai et al [20] and Ke et al [57]. Existing research found that the quantity and quality of black soil in Northeast China have declined and that large amounts of pesticides and fertilizers have been invested in pursuit of high yields, resulting in agricultural non-point source pollution and a decline in soil fertility [58]. The total amount of agricultural carbon emissions in the Northeast region ranks among the top, which is mainly related to the farming method and large-scale mechanization [59].…”

In order to cope with global climate warming, measurement of the low-carbon utilization efficiency (LCUE) of cultivated land, considering carbon sink and carbon emission effects, is proposed. To address this, based on the data of 30 provinces in China, this study conducts a LCUE evaluation system by the MinDS-U-M productivity index model in order to analyze the spatiotemporal patterns and driving factors of LCUE with the geographic detector model and GTWR model. The results show the following: (1) Over the past 20 years, the average LCUE value exhibits a slow increasing trend from 2001 to 2021, which ranges from 0.9864 to 1.0272. Provinces with mid-level LCUE ranging from 1.0000 to 1.0990 account for the highest proportion in each period. (2) The annual growth rate of LCUE in the central region is the highest, where the promotion of green technology and farmland protection policies have played important roles. (3) According to the Geodetector analysis, urbanization rate (UR), irrigation index (IR), grain output value (GOV), precipitation (PR), arable land area (ALA), and environmental pollution control (EPC) are important drivers of the spatial difference of LCUE. (4) The GTWR model shows that the positive effects of ALA and SRT have always been concentrated in the main grain-producing areas over time. UR and PR have strong explanatory power for the space/time differentiation of LCUE, especially in eastern coastal regions. IR has an increasing effect on LCUE in the Western region, and the positive effect of EPC on the LCUE is concentrated in the central region. In order to coordinate regional LCUE contradictions, it is suggested to be wary of land resource damage caused by economic development, warn about the impacts of climate change, and strengthen the supervision of land remediation projects in order to achieve sustainable land management.

“…Regarding the factors influencing the decision to outsource the application process, it was found that community training and promotion of green knowledge, as well as compliance with the rules by surrounding farmers, had a significant positive impact on the choice to outsource. This may be attributed to the influence of the external environment on farmers' production behavior, as indicated by Ma et al (2023). Additionally, the traditional perception of outsourcing services was found to be favorable for green and low-carbon production.…”

Introduction: Promoting low-carbon development in agriculture is crucial for achieving agricultural modernization. One practical issue worth studying is whether outsourcing services can encourage farmers to adopt low-carbon production practices. This study analyzes the impact of pesticide outsourcing services on the low-carbon production behavior of farmers to provide China with practical recommendations.Methods: This empirical study investigates the impact of pesticide outsourcing services on farmers’ low-carbon production behavior using survey data from 450 rice growers in the Ningxia and Shaanxi provinces by endogenous switching regressions (ESR) model.Results and Discussion: Results showed that 1) outsourcing services have a significant negative impact on farmers’ manual weeding behavior, leading to a reduction in the frequency of manual weeding; 2) outsourcing services have a significant positive impact on farmers’ herbicide application behavior. In other words, participation in outsourcing leads to excessive pesticide application; 3) outsourcing services do not support a green and low-carbon production model where manual weeding replaces herbicide application. Due to the imperfect development of the outsourcing market in China, especially in the northwest region, the construction of outsourcing service system is lagging, and it is difficult for non-professional outsourcing services to play a driving role in green and low-carbon production for farmers, who will often choose the lower-cost mechanical application for maximum profit. The policy implication of this study is the need for a comprehensive and objective understanding of the impact and role of pesticide outsourcing services on farmers’ low-carbon production behavior. This understanding can help improve the market, policy, and other external environments for farmers to participate in outsourcing, ultimately promoting the sustainable development of green and low-carbon agriculture. This paper adds to the discussion of pesticide outsourcing services and farmers’ low-carbon production by drawing different conclusions from previous studies, providing a fresh foundation for policy-making.

“…The government encourages farmers to replace chemical fertilizers with organic fertilizers from the view of the quality of agricultural products and the sustainable use of soil [22], and many farmers do so, but farmers are also torn as to whether they should use animal manure for in situ composting or buy commercial organic fertilizers, a question to which policy makers are unable to give an answer. In addition, after a large amount of domestic wastewater in the watershed has been controlled, the impact of agricultural nonpoint pollution on surface water quality is becoming more and more prominent.…”

“…Previous scholars have focused on the occurrence and transport of nitrogen, phosphorus, or organic matter from agricultural surface pollution [18,[23][24][25], but have not paid much attention to estrogen accompanied by manure runoff from farmland, which is often homologous to conventional indicators of water quality pollution. The most effective control measures for agricultural non-point source pollution are source reduction and loss process control [22]. Therefore, we would like to explore the characteristics of manure field utilization and runoff to subsequently achieve the goal of control of SEs.…”

Steroid estrogens (SEs) play a significant role as endocrine-disrupting substances, and one of their major sources is animal manure. However, there is limited information available regarding the loss of SEs in farmland soil after the application of commercial composted animal manure or fertilizers. To address this gap, our study aimed to simulate rainfall and flood irrigation scenarios and investigate the loss characteristics of SEs, as well as Chemical Oxygen Demand (COD), Total Nitrogen (TN), and Total Phosphorus (TP) in runoff from soil–manure mixtures. The results demonstrated that the loss concentrations of SEs (73.1 ng/L of the mean E2β active equivalent factor) presented a potential environmental risk. Additionally, substituting composted manure with commercial organic fertilizers lead to a significant reduction in TP (maximum 56%) and TN (maximum 24%) loss. Consequently, the application of commercial organic fertilizers offers considerable advantages in maintaining nitrogen and phosphorus fertilization efficiency while controlling SEs loss. Furthermore, our study explored the synergistic pollution mechanism among these pollutants and observed significant correlations between SEs and TN, TP, and COD loss concentrations, indicating the simultaneous occurrence and migration of these pollutants in agricultural non-point source pollution. These results provide valuable insights into the environmental risk associated with SEs from agricultural non-point sources.
