Research will evaluate N supplied to corn in multiple field experiments in Virginia. Crop yield responses will be evaluated with pre-season flush of CO2, permanganate oxidizable C, pre-sidedress nitrate test, and end-of-season basal stalk nitrate test. Field experiments will be conducted annually in the Coastal Plain region of Virginia in corn/small grain/soybean rotation. In these trials, experimental design will be a split plot with cover crop as the main plot (rye, hairy vetch, rye+vetch) and N rates on corn as subplots. In the Shenandoah Valley, sites will be corn/small grain forage rotation. Cover crops will vary, but include small grain, crimson clover, and diacon radish.
