Research will evaluate N supplied to corn in multiple field experiments in Pennsylvania. 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. Research in Pennsylvania will leverage 10 site-years of cover crop experiments focused on assessing N retention and supply from cover crop monocultures and mixtures. We will also leverage three on-farm cover crop experiments conducted during two growing seasons to further test the predictive abilities of the flush of CO2.
