The purpose of this study is to evaluate different forms of nitrogen (N) and their impact on yield and profitability.

2017 Kentucky Corn Nitrogen Form Study - Sidedress

In the week following these N applications, less than 0.10 in. of rain was received. This contributed to the lack of urea incorporation and likely caused higher loss via volatilization. The differences in hybrid response to the different forms may be a result of the fact that the high response hybrid utilized the nitrate (NO3) form available in the UAN more quickly, while the N efficient hybrid was less reliant on the immediate N boost from the UAN nitrate.
