| Abstract: | The aim of the study of losses of fertilizer in drained lands is to investigate the influence of drainage on leaching of fertilizer and explore rational measures of fertilizer application and effective drainage design and management practices for reducing ferlilizer losses from the drainage effluent.In this paper the advances of research both in field experimental study and numerical simulation of fertilizer losses in drained lands are reviewed,and the major to pics to be further investigated are discussed. |

| Keywords: | fertilizer losses nitrate-nitrogen(NO3--N) controlled drainage water table management numerical simulation |
