摘要

Groundwater used for irrigation in agriculture changes its quality depending on the number of substances that reach it from different sources. The use of irrigation indices is a tool to improve crop yield and to distinguish risks of salinization and alkalinization of soils due to negative effects of the quality of the irrigation water. In the present research, we assessed the quality of groundwater for irrigation in an agro-industrial karst landscape in Yucatan (Mexico), whose main activities are livestock rearing and forage grass production, to identify changes in irrigation water quality for the period 2003–2023. We evaluated the indices of Sodium Absorption Ratio (SAR), Cation Ratio of Structural Stability (CROSS), Residual Sodium Carbonate (RSC), Effective Salinity (ES), and Potential Salinity (PS). We obtained that the quality of the water for irrigation has experienced changes in these 20 years, oscillating from good to acceptable, being the main driver of the changes observed in the meteorological drought, accompanied by fertilization and non-supervised extended irrigation.
