Water table management, nitrogen dynamics, and yields of corn and soybean

Concern about NO(3)- contamination of surface waters has prompted the development of agricultural water table management systems to reduce NO(3)- loss in subsurface drainage outflow by subirrigating through the existing subsurface drainage lines during the growing season and controlling off-season o...
