Abstract:
This investigation was conducted to assess the physico-chemical
properties of different point of Buriganga and Turag Rivers for
agricultural purpose. Total twenty samples were collected from each of
the rivers to analyze some physico-chemical properties which are
available within the research facility of the department of Agricultural
Chemistry in Sher-e-Bangla Agricultural University. The analytical
parameters were -Color, Odor, pH, Total Dissolved Solids (TDS),
Salinity, Sodium (Na), Potassium (K), Calcium (Ca), Carbonate (CO3)
and Bicarbonate (HCO3). The obtained results of the present study shows
that most of the parameters were not exceed the maximum permissible
limit for irrigation, livestock and aquaculture except Bicarbonate in both
rivers. Bicarbonate was found the ranges of 31 to 91.5 mg/L, whereas the
standard limit of Bicarbonate is 1.50 mg/L for irrigation. From the
statistical point of view, though there were some parameters showed the
positive correlation but most of the parameters were negatively correlated
with other parameters. From the findings, we may conclude that the
quality of rivers water was not so serious problematic for agriculture.
