These fields are filled with shallow [[water]] at least part of the year. Growing these plants is very labor-intensive. A lot of water is needed. Paddy fields started next to the [[Yangtze River]] in China, in the [[Neolithic]] era. Later, their use spread to other areas in [[Asia]]. Paddy fields are built next to [[marsh]]es or using terraces, on a hillside. [[Deepwater rice]] is not grown using paddy fields. It needs water over {{Convert|50|cm}} deep for at least a month. {{stub}} {{Agriculture footer}} [[Category:Agriculture]] [[Category:Rice]]
