Publication Date : 01/08/2014
An appraisal of surface irrigation water quality of the three irrigation projects in each of the senatorial districts of Gombe State, Nigeria was conducted. Water samples were collected from each of the three (Dadin-Kowa, Balanga and Nafada) irrigation project areas which served as the principal water sources for irrigation. The water samples’ pH, sodium, calcium, magnesium, chlorine, carbonate, bicarbonate, sodium ion adsorption ratio, total hardness, total alkalinity, total dissolved solids (TDS) and the residual sodium carbonate were among the parameters analyzed. The result obtained showed that from Dadin-Kowa irrigation project, the mean values of pH, TDS, EC., Na+, Ca2+, Mg2+, C1- and HCO3 were 7.03, 0.70, 0.10, 1.3, 0.18, 0.18, 0.07 and 0.10 respectively. Results from Balanga irrigation project, showed that the mean values of pH, TDS, EC, Na+, Ca2+, Mg2+, C1- and HCO3, were 7.02, 0.62, 0.02, 1.98, 0.22, 0.30, 0.76 and 0.06 respectively. While results from Nafada irrigation project showed that the mean values of pH, TDS, EC., Na+, Ca2+, Mg2+, C1-and HCO3 were 7.10, 0.69, 0.13,1.74, 0.17, 0.21, 0.76 and 0.03 respectively. It was concluded that the results obtained from the three sources indicated that the parameters obtained are within the acceptable range for irrigation, as provided by FAO and therefore recommended for irrigation.
