GPS Meets Agriculture for Precision Farming

mskfisher writes "NASA Science News is reporting a story on a NASA project called Ag20/20, which involves farmers using GPS-aided crop and field analysis to improve accuracy and yields. Instead of blanketing the whole area with a set level of pesticide or fertilizer, they can now vary it via computer, based on IR and soil data gathered from aircraft, satellites, and tractor-mounted sensors."

John Deere is already selling GPS-receiver equipped tractors (marketed as "StarFire receivers") that look about the size of a palm.
