Is there an advantage to placing nitrogen on both sides of the row of corn at planting?
One year of data across our six Practical Farm Research sites indicates, yes. Changing our application of nitrogen from one side of the row to both sides of the row increased yields by 5-6 Bu./A. We also tested higher rates of nitrogen with the 2x2x2 placement. 60 units of nitrogen, applied to both sides of the row, resulted in an additional yield increase of +9.5 Bu./A. A rate this high would not be recommended in a traditional 2x2 system, due to risk of fertilizer burn.
The purpose of this study is to compare starter products, rates, and placements in the Martin-Till® Dual UMO 2x2x2 or Yetter Dual 2968 Series to a traditional 2x2 system and the impact on yield and profitability.
