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.
In 2011, Mosiac released a new App called “Nutrient Removal” for both the iOS and Android. This application provides nutrient removal rates for a wide variety of crops and in some cases by crop yield. ... more
