It has been a dry spring in Iowa--too dry in places. Therefore, nitrogen (N) losses are generally not an issue this year. However, some areas have been wet, especially in eastern and northeastern Iowa, in addition to locations that have recently received heavy rainfall. With another warm fall and open winter, producers in these areas may be wondering whether this is a scenario for repeating the last several years' N losses. Some have recently noted N-deficiency symptoms in cornfields.
