Abstract: In order to study the influencing factors on soil testing and formulated fertilizer (STFF) usage and provide reference for the development of relevant technique, statistical analysis was made according to 142 valid rural residents’questionnaires from Pingyuan County in Shandong Province. The results showed that the application proportion of STFF was only 38% . From the aspect of influencing factors, male farmers had a higher application proportion of STFF than female. The elder had a lower application proportion. People, who were well- educated or had experience of village cadres and working outside, tended to choose STFF. Application proportion of formulated fertilizer increased with the increase of the area of farmland or the proportion of farming income in total income. The government powerful publicity, demonstration households setting, distribution of fertilization card and wide distribution of sale points all could improve the behavior of STFF. Information transmission between farmers was the crucial factor, and whether there were local sale points of formulated fertilizer was the key factor. From the aspect of market environment, the intensively distributed retail points of ordinary fertilizer, numerous varieties of fertilizer products and fierce competition between dealers were the objective factors on farmers’adoption of STFF. In the end, the related causes of fertilization situation were analyzed and corresponding suggestions were proposed in this paper.
