Acre Quotes
Is it always economical to shoot for maximum yield? Research has shown that it's not. It may take the same amount of nitrogen to reach 179 bushels per acre as it does to only reach 170 bushels per acre. It's impossible to determine at what point the nitrogen level is reached to where it is no longer a benefit to gain more yield without a nitrogen rate trial in every field.

Across Quotes
Current nitrogen recommendations assume four things: yield potential doesn't vary year after year, the yield level the soil will support without supplemental nitrogen is negligible, pre-plant nitrogen will be available throughout the growing season, and soil uniformity produces similar yield results across the field. Growers know that none of these assumptions are entirely accurate, and they can potentially be avoided using optical sensors.
