 note = {application/pdf, The performance of the subsurface drainage system was examined and evaluated for the crop diversification, the rice and the non-rice farming, in a paddy field. The subsurface drainage system is designed and installed with the design drainage rate of 20-30mm/d, about 1mm/h, to remove excess topsoil water for rice farming, usually having a 10m spacing. The same system in the non-rice farming field converted from rice farming is expected to have a ten times subsurface drainage discharge, 10mm/h, and to remove excess rainfall which corresponds to the design rate of the surface drainage for non-rice farming., Bulletin of the University of Osaka Prefecture.
