COMPARATIVE ANALYSIS OF SUITABILITY OF SURFACE AND GROUNDWATER QUALITY FOR IRRIGATION: OKE OYI IRRIGATION SCHEME
*Dr. Adejumobi M. A. and Orowale T. N.
This paper presents the results on the comparative analysis of both surface and groundwater of Oke-oyi Irrigation scheme; it was done in order to provide comparative information on the suitability of surface and groundwater system within the scheme. Water samples were tested for its physicochemical quality for Agricultural purposes. The physicochemical analysis were carried out on, pH, EC, TDS, Boron (B), Iron (Fe), Nitrate (NO3), Sulphate (SO4), Bicarbonates (HCO3), Chlorine (Cl) and SAR. Atomic Absorption Spectrophotometry was used for cations and conventional titration for anions, using standard procedures (APHA, 1998). The suitability of both waters for irrigation purposes was being assessed using FAO water quality standard. The result of the surface and ground water quality remains within the safe limit for irrigation purposes. However, there is need to continuously monitor and assess the surface and groundwater quality for irrigation purposes.[Full Text Article]
