Nitrogen losses from farmland, through improper drainage and rainstorm runoff, cause non-point source pollution and limit sustainable agriculture development. We determined the effects of controlled drainage (CTD) and conventional drainage (CVD) on migration responses, the transformation of nitrogen, and NH4 +-N and NO3 --N losses. The results showed that four days after a rainstorm, compared with day one, NH4 +-N and NO3 --N decreased by ranges of 28.7-46.7% and 7.5-47.5% in CTD, which was…
