1. Fall and Spring Soil Residual Nitrate-n As Affected by Irrigation and Nitrogen ManagementNitrogen credit from residual nitrate-N from soil samples collected in spring is widely considered and accounted for in managing N in crop production. That is important from both economic and environmental perspectives. However, there is no incentives for farmers to determine post-harvest soil residual nitrate-N in fall. It is important to note that any difference in fall and spring soil residual nitrate-N would suggest environmental N losses via denitrification or leaching in that fallow period.... B. Maharjan, X.

2. Nitrogen and Sulfur Colimitation to Winter Wheat YieldSulfur has become more limiting for wheat production in the Great Plains, and its deficiency can interact with N availability. The current work reports on yield and yield gaps of three winter wheat varieties as affected by N and S fertilization using the concept of co-limitation (CNS). Field studies evaluating 0, 10, 20 and 40 lbs S/a combined factorials with 50, 100, and 150 lbs N/ac and three hard red winter wheat varieties were conducted in eight environments resulting from the...
