Precision Agriculture -- Best Management Practices for Collecting Accurate Yield Data and Avoiding Errors during Harvest

Combine yield monitoring technology has been in use since the mid-1990s in the United States. Many users focus on the in-cab display as the “yield monitor.” However, a yield monitoring system is made up of several sensors that provide the data to the in-cab display for yield estimation and map generation. The impact plate mass flow sensor located at the top of the clean grain elevator is the most widely used sensor for monitoring grain flow. The goal of this publication is to provide a basic set of best management practices for combine operators to collect accurate yield data during harvest.
