Auto-steer and guidance system adoption on U.S. farms increased sharply in the past 20 years, according to USDA’s Economic Research Service. Farmers indicate they use the technology on more than 50 percent of the acreage planted to corn, soybeans, winter wheat, and cotton as of 2019.
Adoption rates were 58.4 percent of acres planted to corn in 2016, 55.9 percent of winter wheat acres in 2017, 54.5 percent of soybean acres in 2018, and 64.5 percent of cotton acres in 2019. Economic Research Service researchers examined producer responses from various Agricultural Resource Management Surveys to better understand how auto-steer and guidance systems use has evolved.
Using GPS, these technologies visualize and track the position of tractors, harvesters, and sprayers in the field in real time. Autonomous steering permits automatically guided fertilizing, harvesting, and other tasks in the field with minimal involvement from the farmer, increasing field efficiency, reducing operator fatigue, and freeing up operator time in the equipment’s cab.
