Abstract

Many areas of central to southern Iowa have experienced well above normal rainfall this spring, with several large rainfall events (see map). In the early spring, cold soils help reduce potential for nitrate-N loss due to slow accumulation of nitrate and slow denitrification. However, continued wet soil conditions into June with warm soils, prolonged saturation and tile drainage enhance nitrate loss.
