YieldCheck by Precision Planting Inc. provides growers with a simple way to calculate and store corn yield estimates. Users can organize estimates based on client, farm, and field. Also see the location of all of your estimates on a map with satellite imagery. It is as simple as entering kernel counts for three ears of corn and revealing the amount of bushels you can expect at harvest. Subsequently, growers can use the field report feature to see just how much of a difference one additional ear per acre can mean to their operation.
