In recent years, a growing body of literature has explored the determinants and impacts of sustainable agricultural technologies. However, little is known about the relationship between agricultural socialized services that have reshaped the smallholder agricultural system and promoted scale operation in rural China and environmentally friendly agricultural innovation adoption of the farm. Our study examines the effects of agricultural socialized services on the adoption of sustainable agricultural practices (SAPs). In this study, we capture the number of SAPs adopted, unlike most existing studies that analyze the dichotomous decision of agricultural technology adoption. We apply an endogenous-treatment Poisson regression model to analyze using a national representative farm-level survey data set with 1357 farm households from 132 villages in China. The results show that socialized service use has a significantly positive effect on the number of SAPs adopted. Our results suggest that agricultural socialized services can promote the adoption of sustainable agricultural technologies among smallholders, and thus help transform conventional agriculture into sustainable agriculture.

Although it has been widely recognized that land fragmentation has increased chemical fertilizer application, little is known about the role of technology adoption in mitigating these adverse effects. To empirically examine the relationship between land fragmentation, technology adoption and chemical fertilizer application, we developed a mediation model. We applied our analysis to a survey data set encompassing 1388 farm-level samples collected in 14 Chinese provinces in 2019. Our study demonstrated that land fragmentation can not only directly increase chemical fertilizer application but also indirectly increase it by hindering the adoption of agricultural mechanization technologies (AMT’s) and soil testing fertilization technologies (STFT’s). Both are recognized as potent drivers of fertilizer use reductions. Moreover, the adoption of information and communications technologies (ICT’s) can help mitigate the negative effects of land fragmentation on technology adoption, thus reducing chemical fertilizer application intensity (CFAI). However, the direct effects of land fragmentation on CAFI was unaffected by ICT’s. Our findings suggest that ICT’s have revolutionized farmer recognition, promotion and adoption of agricultural technologies by increasing awareness and diffusion of agricultural technology information.

Although various previous studies have explored the relationship between agricultural service adoption and its economic impact, little is known about how it may affect environmental quality, especially chemical fertilizer application. Our study examines the effects of agricultural production services (APSs) on chemical fertilizer use, as well as the effects mediated by farm size, using a national representative survey data set comprising 1321 farm households from 132 villages in China. We show that farms adopting APSs tend to decrease the usage of chemical fertilizer and, thus, have less deviation from optimal chemical fertilizer application. Farms with large sizes are more likely to reduce the usage of chemical fertilizer. Moreover, farm size has a significant mediating effect on the relationship between APS adoption and chemical fertilizer use. In particular, farms adopting APSs are more likely to expand farm size, resulting in chemical fertilizer reduction. Our results suggest that APSs contribute to promoting the scale operation and environmental quality in agriculture.
