Applied Quotes
Nitrogen efficiency in crop production, such as corn, is estimated to be only about 33 percent, suggesting that under current nitrogen recommendation methods the majority of nitrogen applied is going elsewhere other than into the crop. On top of that, it's becoming more of an economic penalty to over-apply nitrogen.

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.

Achieve Quotes
It is intuitive that higher corn yields will result in greater nitrogen demand from the soil, but does that translate into higher nitrogen demand? Investigation of nitrogen rate studies conducted over several years reveals that there is not a strong relationship between maximum yield potential and the amount of nitrogen needed to achieve maximum yield.
