Description :
The aim of this study is to assess the effect of manual tillage on soil movement under conditions prevailing in northern Thailand. The AA. focus on the deep tillage operation (rough tillage) which is the first step in land preparation, as it has the greatest impact on topsoil movement. Soil flux by tillage erosion is quantified as a function of slope angle and slope length. A comparison with soil losses due to water erosion is made, and finally the implications for agricultural sustainibility are briefly discussed.
