Yield Monitor Calibration

Corn  harvest has been underway in my area for over 4 weeks, but it is progressing slowly.  Lots of people have not started yet.  We are going to be harvesting grain under a wide range of conditions this year.  In order to get accurate data, good calibration is a must.  Yield monitors should be calibrated under a wide range of conditions.  Some years we need to simulate those conditions.  This year it will be necessary to actual take readings in the best and worst parts of fields and in areas in between.  Don't over calibrate either.  Adjusting after every load will not help unless conditions change drastically.  The Ohio State University has advice for calibration.  Use your search engine to find other information on calibration.
