Understanding and Cleaning Yield Monitor Data
- R. Khosla and

Yield monitoring enables farmers to quantify small areas of spatial and temporal variability, giving them the opportunity to manage crop inputs when and where they are needed. However, accuracy of yield monitors can vary significantly with the scale or magnitude of harvesting, and since precision farming is focused on managing at a smaller scale, the identification and correction of these errors is critical. Yield monitoring errors can occur in the instantaneous measure of yield, the area over which the measurement is taken, and the location of the measurement within the field. Many software packages correct yield data, including those that come with the yield monitoring systems. We present specific methods to clean yield monitor data. Examples are provided for specific software, but general information with formulas is given so users of various software packages can understand the cleaning process. Users who become familiar with these procedures will become better at mapping, analysis, and decision making.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
