Salt accumulation occurred due to capillary water rise from
salt groundwater is causing a serious farming problem in Northeast
Thailand (Fig. 1). There are many studies concerning salt
accumulation and suggestion for suitable strategies to be taken to
overcome the problems. Dissataporn et al. (2002) suggested that
the groundwater level should be managed below 1.5 m deep from
soil surface to reduce salt accumulation. Also, Kanazawa et al.
(2006) reported that the groundwater level in Nong Thung Mon
village of Phra Yun was 0.51 m deep from soil surface in August
2003 of rainy season. Anase et al. (1997) reported that the
sub-soil drainage system in addition to the banking was effective
for keeping groundwater level lower. Also, Endo and Hara (2000)
reported that the stone layer in soils was suitable measures to intercept the capillary rise of saline water.
However, there are no studies concerning the application of geo-textiles to intercept capillary water rise
from salt groundwater in this area. Therefore, the objectives of this study are to evaluate the application
of chemical geo-textile for intercepting the capillary water rise from salt groundwater and to discuss the
effective leaching measures.
