1. Do Legume Cover Crops Help Mineralize Soil Nitrogen? Nitrogen (N) dynamic is dependent on multiple factor all of which influence in-season plant N availability. Inclusion of a cover crop can have additional impacts on N dynamic by utilizing fall residue soil N, reducing the potential of N leaching. Legume cover crops also have the potential to add additional N to the soil through N fixation. The objective of this study was to evaluate N dynamic of different cover crops (legume and nonlegume) compared to no cover... B. Chim, S. Osborne, R. Lehman Download paper
2. Long-term Crop Rotation Impact on Soil Properties and Crop Response Crop rotations can be part of sustainable agriculture production by their effectiveness depends on understanding how crop rotations affect above- and below-ground crop characteristics. Objectives were to investigate crop rotation effects on shoot dry weight and root characteristics of cereal and grain legume crops at anthesis as well as on grain yield. Rotations were corn (Zea mays L.)-soybean [Glycine max (L.) Merr.], (CS); corn-soybean-spring wheat (Triticum aestivum L.)-field... S. Osborne, R. Lehman, W. Riedell, B. Chim Download paper
3. Evaluation of N Source in No-till Winter Wheat Nitrogen (N) source efficacy is dependent upon product used, application timing, and the condition of the environment in which it is placed. This study serves to look at how different N sources can be affected across different regions of Oklahoma, specifically in a heavy residue, no-till environment. N sources that were included in the study were Urea, Urea-Ammonium Nitrate (UAN), UAN + Anvol, and SuperU. The N sources were evaluated across nine site-years (SY) where each product had four... J.

4. Nitrogen Management in Semi-arid Conservation Cotton Production Systems The Southern High Plains (SHP) region of Texas is one of the largest cotton-producing regions in the United States. Cotton production is hindered by climatic conditions and wind erosion, but attempts have been made to adopt conservation management practices like cover crops and crop rotations to limit these effects. Conservation management practices can reduce a soil’s susceptibility to wind erosion, but their adoption has been limited on the SHP due to producers’ concerns regarding... J. Burke, K. Lewis, W.
