A joint project of the University of Nebraska and Successful Farming magazine observed the harvest operations of three corn farmers using yield-monitoring technology. Two farmers with level fields of high-yielding corn were asked to operate their combines at under-capacity (20-30% reduction in travel speed), over-capacity (20-30% increase in travel speed), and their typical travel speed. The other farmer was observed going up and down a 5-10% slope. The weight of harvested corn measured by the yield monitor was compared to a weigh wagon after each pass. The results showed that yield monitor calibration and combine operational characteristics play an important role in accurate yield monitor response.
