| Abstract | The irrigation practice, it is often the only possibility to ensure agricultural production, especially in tropical regions of hot, dry climate, as is the semi-arid northeastern Brazil. The aim of this study was to evaluate the risk of salinity and sodicity of water for irrigation purposes in the River Basin Pianco Piranhas Acu defined from the control section located along the bridge of BR 230 on said river. 17 measurement campaigns were carried out from NOV./2012 AGT./2013. Samples were taken at three sampling points in the control session, the physico-chemical water parameters were determined following the recommended methodology, the classification of salinity and sodicity of water was based on studies by Richards (1954). From the results obtained it was found that river water Piranha can be classified as water type C2-S1 indicating medium and low sodium content in hardness water salinity was classified as soft water and K, Na+, Ca2+, and Mg2+ maintained in accordance with current legislation. |
