For this\rreason, 56 samples of surface water were collected from each union of Dinajpur sadar upazilla,\rDinajpur. The analysis was included pH, EC, TDS, Ca, Mg, S, P, Na, K, Cl- and HCO3- to evaluate\rthe suitability of surface water for irrigation purposes. Almost all the water samples were within the\rrecommended pH value for irrigation and a great impact on crop production. With respect to\relectrical conductivity (EC) samples were low to medium salinity. For total dissolved solids (TDS),\rall samples were considered as freshwater for irrigation. On the basis of Ca, Mg, S, P, Na, K, Cl-\rand HCO3- all samples could safely be used for irrigation and would not affect theeninfo:eu-repo/semantics/openAccessZiraat MühendisliğiArticle17821017915151469
