Description :
On an experimental site in Hsinchu county, Northern Taiwan, a terraced rice field was used to investigate the soil erosion under the regular cultivation of rice in 2005, fallow in 2006, and planting with green manure in 2007. The results show that infiltration rates significantly increase when a terraced paddy field is under fallow or is planted with green manure; the paddy is more vulnerable to embankment collapse and increased the rates of soil erosion. The comparison revealed that soil conservation using rice-planted terraced paddy was more effective than that resulting from other uses. The government should formulate effective measures and maintain sustainable rice planting in the terraced paddies.
