| dc.description | Water is the most essential natural resources on the earth. Water quality for irrigation is a
prime factor for successful crop production. Quality of water is not only essential for
irrigation but equally important for drinking, domestic, livestock, fish production and
industrial purposes. Clean water is also necessary for human health and livelihood as well as
being interwoven into many cultures. Water is the fluid of life not only for human beings but
also for any living organism. The main sources of water in Bangladesh are surface waters in
rivers, reservoirs, lakes, canals and ponds, and the ground water in deep and shallow aquifer
(Ahmed and Rahman, 2003). Soil properties, crop yield and quality will be deteriorated if
low quality water is used for irrigation (Sarker et al., 2000 and Sarker et al., 2003). | en_US |
| dc.description.abstract | River water samples were collected from three rivers (Esamoti, Punarbhaba and
Garbessary) of Dinajpur Sadar, Upazilla Dinajpur, Bangladesh during the
months of August, December and April of the year 2014-2015 and analyzed for
its quality and suitability for agricultural and aquatic purposes. Analyses were
included pH, EC, temperature, dissolved oxygen (DO), alkalinity, cations (Ca2+
,
Mg2+, Na+
and K+
), anions (Cl-
, HCO3
-
, PO4
3-
and SO4
2-
) and TDS (total
Dissolved Solids) were done. Several variables such as SAR (Sodium
Adsorption Ratio), SSP (Soluble Sodium Percentage) and hardness were also
computed. Overall we found that the river water were acidic in nature (pH
varied from 5.3 to 7.1) and could be suitable for agricultural and aquatic uses.
River water samples contained Ca2+, Mg2+ and Na+
as the dominant cations and
HCO3
-
and Cl- were the dominant anions. According to TDS and SAR value, all
samples were classed as “fresh water” and “excellent” categories. The soluble
sodium percentage (SSP) of all water was under ‘excellent’ and 'good' classes.
All samples were within 'soft' class regarding hardness. Based on SO4
2-
, Cland
PO4
3-
all river water samples were within the 'safe' limit for irrigation. The DO
concentration was suitable for fish production but more DO level should be
present for all aquatic life especially for fish production | en_US |
