How & Why Do Farmers Use GPS in Farming?

Technology seems to have invaded every area of modern life. Farming is no exception to this rule. Just as tractors replaced draft horses as the main energy source to drive planting and harvesting equipment, global positioning systems have replaced human eyes and experienced guesswork in tractor guidance, field location, leveling and a number of other tasks.

Precision Plowing

Prior to the wide availability of GPS, tractor operators relied on visual cues to keep furrows aligned. Whether these were straight or following the contour of the field, making efficient use of the available land required constant attention when guiding the plow. GPS, along with other modern guidance technology and automatic steering systems, can place furrows in a field with millimeter precision.
