Abstract
RESUMEN: La investigación tiene como objetivo general demostrar el indicie de contaminación de los suelos por el uso de las aguas residuales, la investigación fue de tipo experimental que consistió en recoger 5 muestras de terrenos de cultivo con el propósito de verificar el potencial de Hidrógeno (pH), Conductividad Eléctrica (C. E.), Fosforo (P), Potasio (K), Carbono (C), Materia Orgánica, Nitrógeno (N), el análisis mecánico, la Capacidad de Intercambio Catiónico (CIC), cantidad de Calcio ( Ca +2 ), magnesio ( Mg +2 ), Potasio ( K + ), concentración de Sodio ( Na + ) e Hidruro de Calcio ( Ca +2 + H + ), los resultados relevantes destacan que la mayoría de muestras presentan concentraciones superpones de componentes químicos, a los propuestos por La Organización de las Naciones Unidas para la Alimentación y la Agricultura (FAO, 2018). En base a los datos se concluye que el exceso de pH encontrado en los suelos lo hace alcalino, el exceso de fósforo, potasio, carbono, materia orgánica y la regularidad del nitrógeno hace que los suelos no desempeñen sus funciones normales en el cultivo de la plantas y que los valores miliequivalentes por 100/g superan los límites permitidos la normatividad vigente.
ABSTRACT: The general objective of the investigation is to demonstrate the index of contamination of the soils due to the use of wastewater, the investigation was of an experimental type that consisted of collecting 5 samples of farmland with the purpose of verifying the potential of Hydrogen (pH) , Electrical Conductivity (EC), Phosphorus (P), Potassium (K), Carbon (C), Organic Matter, Nitrogen (N), mechanical analysis, Cation Exchange Capacity (CEC), amount of Calcium (〖Ca〗 ^ (+ 2)), Magnesium (〖Mg〗 ^ (+ 2)), Potassium (K ^ +), Sodium concentration (〖Na〗 ^ +) and Calcium Hydride (〖Ca〗 ^ (+ 2) + H ^ +), the relevant results highlight that most samples present superimposed concentrations of chemical components, to those proposed by the Food and Agriculture Organization of the United Nations (FAO, 2018). Based on the data, it is concluded that the excess pH found in the soils makes it alkaline, the excess of phosphorus, potassium, carbon, organic matter and the regularity of nitrogen makes the soils not perform their normal functions in the cultivation of the plants and that the milliequivalent values per 100 / g exceed the limits allowed by current regulations.
