Rapid socio-economic changes in China, such as land conversion and urbanization etc., are creating new scopes for application of precision agriculture (PA). It remains unclear the application effective and economic benefits of precision agriculture technologies in China. In this study, our specific goal was to analyze the impact of precision seeding and laser land leveling on winter wheat yield, grain quality, residual soil nitrogen, benefit/cost ratio and net return. Three treatments was carried out in a winter wheat of the central plains of China, namely, precision seeding, integration of precision seeding and laser land leveling, and local large-scale conventional farming, respectively. Our results showed that: (1) winter wheat yield was increased by 7.8 % in the single precision seeding treatment while significantly increased by 23.2 % through the integration of precision seeding and laser leveling technologies. There was no significant difference of the winter wheat protein content among the three treatments. (2) Both the single technology and the integrated technologies reduced the concentration of soil nitrate nitrogen and ammonium nitrogen at the depths of 60 cm, but, the significantly reduction was only found in soil ammonium nitrogen. (3) Compared with conventional farming, applying precision seeding improved the benefit/cost ratio by 5.9 %, and the integrated technologies improved by 16.6 % and 7.9 % under the two scenarios of "having" and "not having" laser leveling subsidies. These results clearly indicated that the application of precision agriculture technologies can significantly enhance the yield, reduce the residual soil nitrogen and improve the economic benefits, without affecting the winter wheat quality. Supporting policies can significantly promote the popularization and application of precision agriculture technologies in China.
