Abstract

Soil salinity has
become one of the environmental issues around the world. The most typical
example in Turkey was the soil salinization in Harran and Akçakale Plains in
recent years. Especially the Harran Plain has the big potential of water and
land resources. Irrigated farming is common in the plain. Excessive and
uncontrolled irrigation contributed the high groundwater level and soil
salinity in the region. Deficiency of drainage network in the farmlands was the
most important factor on the salinity. In-field drainage systems are newly
established. In some areas, irrigation is conducted through the main drainage
channel with high salt content (13.5 dS/m). On the other hand, pumping
irrigation waters in Akçakale region have high salt content. This problem has
grown especially when dealing with low-permeable soils where conventional
remedial techniques are inadequate and often ineffective. Electrochemical
treatment is an innovative and clean technology for the restoration of saline
soils. This process has proven to be the most effective, promising technique
for the optimal and sustainable improvement of salt-affected soils.
