Automated unmanned sowing machines have been adopted, replacing manual seed planting ones, as a means to raise efficiency while keeping precision. The machines are supported by the BeiDou Navigation Satellite System. One can complete sowing seeds in an area of 100 mu (about 16.5 acres) a day, which promotes the level of automation and intelligence. It costs around 20,000 to 30,000 yuan (about 3,100 to 4,700 U.S. dollars) to transform an ordinary sowing machine into unmanned one.
