Precision agriculture delivers localized crop production management through a number of different technologies. One of them, variable rate technology (VRT), adapts machinery and field operation equipment—such as sprayers and seeders—to automatically control input flow rates.
Farmers can even use VRT to plant different types of seeds at different locations with a single pass of the tractor. However, installing and maintaining equipment with VRT capabilities comes at a relatively high cost. Empirical estimates showed that, in 2010, VRT still improved profits on corn farms by about 1 percent.
Between 2010 and 2013, VRT adoption also reached about 20 percent of planted acres in corn, soybean, rice, and peanut production. This chart appears in the ERS report Farm Profits and Adoption of Precision Agriculture, released October 18, 2016.
