Precision agriculture

Definition

Precision agriculture is an innovative farming management concept that uses technology to monitor and manage field variability in crops. This approach integrates data from various sources, such as GPS, sensors, and satellite imagery, to optimize field-level management regarding crop farming. By doing so, it enhances resource efficiency, reduces waste, and improves overall yield while considering the environmental impacts of agricultural practices.
