Over-using of agricultural chemical fertilizer in long term causes serious agricultural non-point source pollution. Education mechanism which aims to raise farmers’ awareness and guide farmers to consciously choose friendly environmental production behavior can control the occurrence of agricultural non-point source pollution from the source. Based on the data of 626 questionnaires in Shaanxi Province，this paper uses propensity score matching method to estimate the effect of soil testing and fertilization and Chinese and English projects on farmers’ reduction of chemical fertilizer use. The results of empirical research showed：the education guidance project for controlling agricultural non-point source pollution can affect farmers’ fertilizer input，and the influence of different information transmission routes on farmers is different.
