Soil: The study area soil types are more important, since it is the
main criteria in the recharge of groundwater and agricultural
production. The area is covered with sandy clay in the
Sankarapari area (western part) red soil (Sandy loam to Sandy
soil) in the central part and alluvial sandy soils (Coastal area) in
the eastern part (figure 3). The maximum soil thickness is about
3m. The sandy soils originated from sandstones and these have
low soil moisture retentivity.
