Effect of Crop Type and Season on Nutrient Leaching to Tile Drainage Under a Corn-Soybean Rotation

Subsurface tile drainage is a significant pathway for nitrogen (N) and phosphorus (P) transport from agricultural fields. The objective of this study was to evaluate N and P loss through tile drainage under corn and soybean production in a corn-soybean rotation typical of agricultural management across the eastern Corn Belt of the US Midwest.
