Treatment Information
Two strips of NH3 (82-0-0) were applied at 75 lbs N ac-1 on June 8 at V3. This fertilizer was applied in a band between each row at 4-6” deep.
Agronomic Information and Weather
Soybeans with a 1.9 maturity rating were planted in 30” rows on May 6 in a ridge-till system. The seed was not treated or inoculated. The previous crop was corn. A foliar insecticide was applied at R3. The field received approx. 6.4 in. of rain and accumulated 1830 GDDs from June 1 through August 31. This was drier and warmer than the average of 10.1 in. and 1887 GDDs.
Results
Results
On average, NH3 did not increase yields. However, it appears that yield response may have occurred through the highest yielding zones of the field. These results were consistent with another nearby trial in Lake Co. Soybean yield response to N has been observed in several SD on-farm trials over the past three years. However, responses across an entire field have been rare. Therefore, N trials in soybeans are needed in the future to better-understand this system.
