Progressive growers know that they need to be able to differentiate their harvested crop in the market. By knowing the quality of every combine tank load, the control of that quality is in the hands of the farmer. Whether the decision is to segregate loads or blend loads, the grower is making the decisions instead of waiting to see what is offered at the elevator.
Quality characteristics such as protein have a strong link to nitrogen use. Knowing where that protein varies in the field is a powerful tool in deciding where and how much nitrogen fertilizer to apply, with the result of improving nitrogen utilization and optimizing maximum economic yields. Profitability maps are more meaningful with quality and yield information and on farm testing such as strip trials become useful.
