Precision Agriculture

Precision agriculture is a farming method that uses the global navigation satellite system (GNSS), sensors on the ground, and drones in the air to study individual farm fields. With these tools, farmers can fine-tune their approaches to planting, harvesting, and maintaining crops to save themselves time and money. Minnesota farmers have used the technology since the early 1990s to improve crop yields while protecting the health of their soil.
