In the late 1990s the advent of GPS-based location-tracking technology and computer analysis launched an agricultural revolution. U.S. farmers began using the new technology to “see” bigger variations within their fields and animals than they had ever imagined. Information became a new crop of the 21st century, making farmers more efficient and sustainable but increasingly technologically dependent.
Technology Transforms Farming
The satellite-based GPS system was first developed by the U.S. Departments of Defense in the 1970s. In the 1990s agricultural engineers began combining on-the-go crop yield readings with GPS tracking to create crop yield maps.
