Participants will have the ability to decide on the amount of pre-plant and/or in-season (via side-dress and fertigation) nitrogen fertilizer in the form of UAN 32%. All plots will receive a baseline 5 gallons per acre of starter fertilizer (10-34-0) at time of planting. Timing of pre-plant will occur on April 3rd (or earliest convenient date), side-dress will occur between V4 and V6 growth stages, and fertigation at V9, V12, VT/R1 and R2 growth stages. Maximum side-dress amount is 140 lbs/acre and maximum fertigation amount per application is 30 lbs/acre. Pre-season soil sampling report is shown in attachment. A custom application cost of $7.00 per acre will be charged for the pre-plant and side dress applications. An application fee will be charged for chemigation and will be determined prior to the side dress operation. Participants will only be able to change nitrogen application amounts, all other nutrients and micro-nutrients will be applied to all plots based on UNL recommendations.
