Areas of high salinity potential: Areas of high salinity potential are defined as those places where
geology, ground water quality, land form and land cover predispose a location to salinity. These conditions are
similar to those occurring in areas of known salt crust. These areas are common in lower terrace and paddy field
with sparse or no vegetation in conjunction with the high total dissolved solid and high ground water yield. This
includes lower slopes, relatively flat and poorly drained soil.
Areas of moderate salinity potential: these areas cover the site wherever the conditions are less severe
than those occurring in areas of high salinity potential. These areas are also in lower terrace, moderate ground water
quality and moderately drained soil.
Areas of low salinity potential: Areas in which salinization factors do not occur together and are of minor
importance. Soils are somewhat well drained and underlying strata are low in the total dissolved solid.
Areas of non-salinity potential: these areas cover the site wherever they meet one of these conditions:
1.beyond the rock salt “Maha Sarakham” Formation 2.upper terrace 3.mountain 4.dense vegetation 5.good quality of
ground water.
The map information presented in this paper is available as potential zone. This provides no guarantee that
the salinity will not develop. Further information collected will be used to update the map. The map should be used
in conjunction the other publications and related experiments.
