Ensuring the availability of clean water represents a fundamental objective worldwide, since water is an essential resource for sustainable development. Volumes of fresh water available for agricultural and urban-industrial use worldwide have decreased considerably due to the excessive use of surface and groundwater destined for agricultural irrigation for the production of food for a constantly growing population. The objective of this study was to evaluate the physicochemical quality of groundwater and determine its aptitude for agricultural use through the criteria of salinity, sodicity and toxicity in the Department of Lavalle in Corrientes province, Argentina. The evaluation and characterization of the physicochemical quality of the waters analyzed for irrigation and applications of phytosanitary products by means of the determination of cations and anions present indicate that they do not show inconveniences to be used in agriculture. According to the Riverside laboratory classification, 73 % of the water samples presented low salinity, all with low sodium content, suitable for irrigation in most cases; and 26 % of the samples with moderate salinity, suitable for irrigation, with low sodium content. In addition, it should be noted that the determination of hardness, nitrate, phosphates and potassium are important data when making a fertilization plan. In the case of toxic ions such as chlorine and sodium, the samples presented low values, so they do not represent a problem for their use.

Palabras clave : water quality; underground water; cations; anions; agricultural holdings; irrigation.
