Nebraska Soybean N Trials
Figure 1. Photos of one site of the Nebraska Extension Soybean Management Field Day research (2013) that compared the effects of several nitrogen treatments on soybeans. Pictured is the zero N control on the left and the 400 lbs/ac split N application on the right. Averaged over four sites the control yielded 73.4 bu/ac and the 400 lbs N averaged 78.9 bu/ac.

Study Unearths Benefits, Limits of Fertilizing Soybeans

September 29, 2017
Soybean crops in highly productive fields demand more nitrogen than natural sources alone can supply, says a new study from University of Nebraska-Lincoln and Argentine researchers. In fields with the potential to produce 80-90 bushels per acre, researchers found fertilizer increased yields by up to 10 bushels per acre.
