- Situation 3: Irrigation was used when soil moisture dropped to 1%. a. If irrigation begins when soil moisture reaches 49%, what application of nitrogen will result in the lowest percentage of protein in wheat grain? b. If irrigation begins when soil moisture reaches 34%, what application of nitrogen will result in the same protein content of wheat grain as begin- ning irrigation when soil moisture reaches 1%? c. If you irrigate when soil moisture reaches 34%, how much nitrogen should you apply to achieve a 13% protein content in wheat grain? d. Does Figure 1.45 indicate that, for nitrogen levels at 45 pounds per acre or higher, increased protein content in wheat grain is associated with higher or lower soil moisture? 14 1% 13 34% 12 49% * 11+ 10+ 6. 20 40 60 80 100 120 140 Nitrogen FIGURE 1.45 Protein content versus availability of nitrogen % Protein
