Water and nitrogen management in wheat-maize production on the north China plain

The North China Plain supports a large number of highly intensive small farms that produce winter wheat traditionally followed by a summer crop of maize. ACIAR funded a five-year project from 1998 aimed at improving the efficiency of water and fertiliser use in this wheat-maize production system. This study was commissioned to assess the economic and environmental benefits of project putputs at farm and community level.
