Yield Monitoring

Yield monitors use GPS, GIS, a computer, and sensor technologies to accurately measure the amount of crop harvested at a specific location and time.  Yield monitors are installed on harvesting equipment and are used on a variety of crops including corn, wheat, soybeans, sugar beets, potatoes, and cotton.  In addition to measuring yield, these systems allow for the recording of crop moisture, elevation, variety, and a number of other harvest variables.  Yield monitors use sensors to measure the crops’ mass or volume and are found to be accurate to +/- 3% of actual harvested amounts, but require routine calibration to maintain accuracy.  The volume or mass measurements are recorded in the on-board computer to produce indirect yield measurements.  GPS provides the field location for each measurement.  The location and yield data are recorded onto a storage device and transferred to a desktop AgGIS package for processing, viewing, and analysis.  Maps depicting yield variations across fields can be developed and used to provide farm management decisions to improve crop productivity.
