The purpose of this study is to evaluate various planting intervals after a pre-plant incorporated application of anhydrous ammonia, placed at two different depths, and its effect on emergence and yield.

3-YEAR NITROGEN DEPTH & TIMING STUDY YIELD AVERAGE

Good conditions and soil moisture at planting likely limited the anhydrous band expansion. Excellent post-planting growing conditions allowed for fast early growth. Beck's Three-year PFR data confirms that the depth of application is key, especially if you plan to plant within a week of the application.
