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.

2019 Ohio Corn Nitrogen Depth and Timing Study - Anhydrous Ammonia

When it comes to anhydrous applications, placement and depth are key. In this trial, early applications may have led to higher N loss from early-season rains.
