ABSTRACT
Soil salinity is one of the major problems in the coastal zone of Bangladesh. About 53%
of the coastal areas are affected by salinity which is causing decline in soil productivity
and crop yield which results in severe degradation of environment. Our present study
was conducted to determine soil salinity status in Dacope upazilla of Khulna District.
To fulfill the objectives of our study soil sampling was done by random sampling
method at 0-15cm depth and samples were collected from agricultural, riverbed and
embankment site. These locations are in Dhaki, Vodra and Chunkuri in Dacope
upazilla. Salinity has a detrimental effect on soil physical and chemical properties in
Dacope upazilla. Soils pH was found higher which expresses moderately alkaline.
Electrical Conductivity (EC) of soils varied from 510.67µs cm

expressing moderate to high salinity. Organic matter content is pretty low to medium
(0.23 to 1.96) %. Nutrient deficiencies for total nitrogen were quite dominant in the
study area. Total Phosporus, potassium and Sulfur contents were in medium to low
level and the amount of accumulated salt was found high. The findings of the research
showed that the salinity in study areas is increasing day by day which were affecting
crops and vegetation depending on degree of salinity. So the present study suggests to
imply necessary management plan to reduce salinity in Dacope upazilla of Khulna
district.
