Ano: 2010 URL: http://purl.umn.edu/61667 The Value of Regional Annual Nitrogen Needs Information for Wheat Producers in Oklahoma AgEcon Roberts, David C.; Brorsen, B. Wade; Raun, William R.; Solie, John B.. Crop producers are increasingly interested in reducing nitrogen use without sacrificing yield.
