摘要 Chemical fertilizer plays an important role in increasing food production in China. Nevertheless, excessive nitrogen fertilizer use in China has resulted in severe environmental problems. The goal of this paper is to examine the impacts of an improved nitrogen management (INM) training experiment on farmers’ chemical nitrogen (N) use behaviors in maize production in China. Based on household data collected from 813 maize farmers in Shandong, China, this study finds that while INM training can significantly reduce farmers’ N fertilizer use, an INM training is not sufficient to change farmer’s practices significantly, and farmers only partially adopted the recommended INM. This study reveals that China faces challenges to transform its agriculture to a low-carbon one. The research also sheds light on China’s extension system and future technologies in meeting the objectives of reducing the excessive nitrogen fertilizer use in agricultural production.
