      abstract = {Recent natural gas price increases have resulted in  acutely higher fertilizer prices. Profit and environmental  concerns have increased interest in identifying optimal  nitrogen application rates. Previous estimates of the  profit maximizing nitrogen rate (PMNR) have been estimated  assuming that price is fixed and exogenous of yield. We  construct a model in which price is correlated to yield  shocks, and estimate the PMNR. We find that incorporating  correlation information systematically affects the PMNR,  however, these effects are small.},
