In the past 15 years，Chinese farmers have made great progress in scientific fertilization due to the contribution of formula fertilization by soil testing. The purpose of this paper is to summarize the results of the project in building the basic database of soil and crop fertilizer efficiency，promoting the popularization of fertilizer technology，and improving the level of scientific fertilization of farmers. The project is divided into three phases including Scale expansion phase(2005～2009)，Integral construction promotion phase(2010～2014)，and Green development phase(2015～2019). To summarize progress，the data collected from national formula fertilization by soil testing management system were used. The research we have done suggests that in the past 15 years，the project has collected 20.467 million soil samples，1.526 million plant samples，analyzed 18.339 million soil samples，1.299 million plant samples，conducted 403000 experiments，767000 field demonstrations，released 311000 fertilizer formulas，and trained 326 million farmers. In 2019，the amount of fertilizer application for the country and per hectare decreased by 10.3% and 10.1% from the peak，respectively，the nitrogen use efficiency increased by 11.7 percentage point，and the area covered by soil testing and formula fertilization technology reached 138 million hectares. The achievements of the project were obviously，however，there were some problems in management and technology. It is recommended to focus on the agricultural green development，consolidate the basic work of formula fertilization by soil testing，strengthen the promotion of fertilizer technology，and serve the implementation of the rural revitalization strategy.
