Figure 2. Nitrogen supply and uptake as impacted by timing of sidedressing (NoN = starter only; Nrich = 300 lbs N per acre at planting; V4, V6, V8, and V10 = sidedressing of 180 lbs N per acre at the designated growth stage). The trials were conducted on continuous corn fields without a recent manure history at the Musgrave Research Farm in Aurora, NY).
