PRECISION FARMING

Precision farming, sometimes called site-specific farming, is an emerging technology that allows farmers to adjust for within-field variability in characteristics like soil fertility and weed populations.
Precision farming uses the global positioning system (GPS), consisting of 24 satellites that transmit signals picked up by user receivers to define the receiver's location. With this information and on-board sensors, farm equipment can monitor crop yields and guide applications of crop inputs like fertilizers and herbicides.
Precision farming has the potential to reduce costs through more efficient and effective applications of crop inputs. It can also reduce environmental impacts by allowing farmers to apply inputs only where they are needed at the appropriate rate.
