Tips for ‘late’ applications of nitrogen
Dribbling 28% solution with drop nozzles as a narrow band on the soil surface is an alternative approach that can help reduce foliar burning. Dribbling 28% is also a more efficient use of N than broadcast surface application because it helps reduce N volatilization. Urea stabilizers may be considered for this application, but tillage is a major deciding factor on whether or not they are necessary. High residue corn fields may benefit from urea stabilizers, but low residue fields are less likely to benefit. At this point of the growing season, and the need for plenty of nitrogen by the crop, we do not recommend nitrification inhibitors. We also rarely see positive responses to nitrification inhibitors when N is sidedressed.
Can I Apply N to Every Other Row?
Research in Indiana, Illinois and Iowa has all shown that farmers can knife ammonia or N solutions in every other row middle (60 vs. 30 inch spacing) with no reduction in yield. The only caution is that extra attention must be paid, especially in wet conditions, that no knives plug with soil. A plugged knife in 60 inch spacing gives 4 rows with no N and will seriously reduce yields.
