1. Cover Crops and Tillage Interaction on Claypan Soils of Southern IllinoisIncreased nutrient leaching due to agricultural practices such as tillage and fertilization is a significant environmental concern. Nitrogen (N) mineralization stimulated by tillage can increase the risk for nitrate leaching before subsequent crops have an opportunity to take up the N released by microbial activity. An alternative measure for reducing potential nutrient loss via leaching and runoff is use of cover crops (CCs). A field experiment was conducted at the Southern Illinois University’s... S.

2. Cereal Rye and Hairy Vetch Cover Crops for Improving Soil and Water QualitySoil and water quality benefits of cover crops (CCs) have been inferred only from plot scale studies. Replicating cover crops at the watershed scale and expecting similar results to that of plot scale studies need further research. Therefore, cover crop study at Southern Illinois was carried at the plot as well as the watershed scale. The objectives of plot scale study were (i) to evaluate the contribution of fertilizer and soil organic matter (SOM) to N leaching under corn/soybean cropping... S. Gurbir, K. Williard, J.

3. Does Nitrogen Management in Winter Wheat Affects Its Yield and Nitrate-N Leaching in a Wheat-Soybean Double Cropping System?Conventional corn (Zea mays L.)-soybean (Glycine max L.) rotation contributes to nitrate-N and phosphate leaching to waterbodies causing water quality concerns. Two strategies that could minimize N and P losses include (i) incorporating winter rye (Secale cereale L.) (WR) as a cover crop to capture residual nutrients or (ii) intensifying the corn-soybean rotation with winter wheat (WW) (Triticum aestivum L.) (Double cropping). Double cropping WW at a right N...

4. Short Term Effect of Double Cropping and Cover Cropping on Soil Physical PropertiesIntegrating cover crops into corn (Zea mays L.)-soybean (Glycine max L.) rotation has been promoted as a sustainable practice to reduce soil erosion, enhance soil health, and improve agricultural sustainability. However, growers are less inclined to include cover crops into their cash crop rotations especially winter cereals such as winter rye (Secale cereale L.) behind corn. One strategy to minimize the fallow period in corn-soybean rotation is by intensifying the corn-soybean... F. Sheikhi shahrivar, O. Ola, O. Guzel, K. Gage, K. Williard, J. Schoonover, S. Mueller, A.

5. The Effect of Nitrogen Management in Winter Wheat on Nitrous Oxide Emissions in a Wheat-Soybean Double Cropping SystemNitrogen fertilizer management plays a critical role in nitrous oxide (N₂O) emissions in agricultural production systems. This study investigated the impact of nitrogen application in a winter wheat (Triticum aestivum L.)-soybean (Glycine max L.) double cropping system on winter wheat biomass production, grain yield, and N₂O emissions. The experiment was conducted at the Agronomy Research Center (ARC), Carbondale in Southern Illinois University, IL using a Randomized Complete... O. Ola, O. Guzel, K. Gage, K. Williard, J.
