Stalk nitrate concentrationvs difference from EONR

Stalk nitrate concentrationvs difference from EONR
Graph showing the relationship between cornstalk nitrate-N concentration and the difference in N rate from the economic optimum N rate (EONR). Positive N-rate values indicate rates greater than the economic optimum, negative values indicate rates less than the economic optimum, and zero is at the economic optimum rate. Data from J. Sawyer, 1999–2002 N-rate response trials with continuous corn (CC) and corn following soybean (SC).
