The district of Pisac in the Cusco region, due to its climate, has vast expanses dedicated to agricultural activities, which do not have studies regarding the salinity of its agricultural soils. One issue is that the quality of their agricultural products may be due to soil salinization, where farmers have observed problems in the development of their crops. The physicochemical characteristics, salinity, RAS, and PSI of the irrigation water and agricultural soils have been evaluated during the dry and rainy periods. The soils have shown low salinity and sodium in both periods, ranging for EC from 0.419 to 2.140 dS/m, pH from 7.2 to 7.9, and PSI from 0.57 to 1.47%. Likewise, the soils have shown low fertility, low water retention, and high alkalinity. The irrigation water has shown an EC of 285 to 486 μS/cm and an SAR of 0.36 to 0.65 meq/L, being classified as C2S1, which would affect th...

En el presente estudio, el distrito de Pisac de la provincia de Calca, región Cusco, debido a su climatología, cuenta con amplias extensiones destinadas a actividades agrícolas. Sin embargo, no cuentan con una línea base científica respecto a la salinidad de sus suelos agrícolas, el cual es un factor que comúnmente incide negativamente sobre el correcto desarrollo y crecimiento de las plantas. Por lo que, conocer la salinidad en estos suelos agrícolas es necesario; debido a que en concentraciones altas generan problemas de permeabilidad y baja disponibilidad de agua y aire, así como efectos osmóticos. En este sentido, el objetivo de este estudio ha sido “evaluar el efecto del agua de regadío sobre la salinidad de los suelos agrícolas en el distrito de Pisac - Cusco 2023”. Para ello, se recolectaron 10 muestras de los suelos en el periodo seco y 10 muestras en el periodo l...
