1. Effects of Residue Placement on Co2 Loss in an Irrigated, No-till Corn System It is well known that residue management practices that leave crop residue on the surface, such as no-till agriculture, promote soil fertility. However, the effects of such practices on carbon sequestration can be highly variable. To better understand how residue management impacts the loss of carbon through mineralization, we investigated the effects of residue location and addition on CO2 produced from residue decomposition under no-till irrigated continuous corn in Northern Colorado. Over... H. Oleszak, F. Cotrufo, S. Leichty, C. Stewart Download paper
2. Nitrogen and Sulfur Colimitation to Winter Wheat Yield Sulfur 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...
