Abstract :
Soil salinity is a serious problem for agriculture
especially in irrigated areas. It occurs in irrigated soil
because of the accumulation of soluble salts due to the
continuous use of irrigation waters containing high or
medium quantity of dissolved salts. The region selected for
the present study is southern Shirol tahsil of Kolhapur
district. It is located between 16° 33? 17? to 16° 43? 32? N
latitude and 74° 29? 56? to 74° 41? 30? E longitude occupying
an area about 22,840 hectares. The exact position of sampling
point in latitude and longitude was identified by GPS. pH
value and Ec value are measured by using pH meter and Ec
meter respectively. In this study, an attempt has been made
to measure the levels of soil salinity by assessing Ec and pH
value through IDW GIS techniques. The analysis reveals that
deterministic interpolation method like IDW can be
successfully used to generate exact continuous surface for
saline soil assessment. In denudation slope area, the problem
of saline soil is much prominent than surrounding area.
Particularly sugarcane has virtually mined nutrients from
the soil and the problem of saline and alkaline soil has
emerged. Unscientific agricultural practices and irrigation
methods, overuse of agro-input, frequent flooding of plain
areas have caused degradation in the southern Shirol tahsil.
