Resumen
En la parroquia Colonche la agricultura depende del agua almacenada en reservorios que son abastecidos por una represa, los cuales no cuentan con información sobre su calidad. Por ello, el presente estudio analizó la calidad del agua para riego en suelos agrícolas de la parroquia Colonche. Se realizó un muestreo aleatorio de tipo simple y compuesto para agua y suelo respectivamente en diciembre del 2020. Posteriormente, se determinaron cationes, aniones, pH, CE, SDT, dureza, textura del suelo e índices de salinidad y sodicidad. Las aguas y los suelos fueron alcalinos. Además, todos los parámetros del agua cumplieron con la normativa nacional y con las recomendaciones de la FAO, excepto potasio y carbonato. Según la clasificación de la FAO, el agua tuvo ligeras restricciones, ya que presentó alto riesgo de salinidad, pero bajo riesgo de sodicidad de acuerdo a los índices. Esto no reduciría la infiltración del suelo, cuya textura fue arcillosa.
In the Colonche parish agriculture depends on the water stored in reservoirs that are supplied by a dam, which do not have information about its quality. Therefore, this study analyzed the quality of water for irrigation in agricultural soils of the Colonche parish. A simple and compound type random sampling was carried out for water and soil respectively in December 2020. Subsequently, cations, anions, pH, EC, TDS, hardness, soil texture, and salinity and sodium indices were determined. The waters and soils were alkaline. In addition, all the water parameters complied with national regulations and FAO recommendations, except for potassium and carbonate. According to the FAO classification, the water had slight restrictions, since it presented a high risk of salinity, but low risk of sodicity according to the indices. This would not reduce the infiltration of the soil, whose texture was clayey.
