Trends of key irrigation water quality parameters in the endangered watercourses in Vojvodina (Serbia)

Abstract

rrigation water quality is presented by ion concentrations and parameters such as electroconductivity (EC), pH and total hardness (TH). Enlarged values of these indicators can have negative effects on irrigated soils and crops. Watercourses, highly endangered by different influences, were selected for analysis: Krivaja, Jegrička, Plazović, Vrbas-Bezdan (canal of the DTD hydrosystem) and Zlatica. The trend analysis was performed on the basis of monthly parameter values, published by public institutions (period 2001-2020). Because considered parameters have a seasonal character, seasonal Kendall test was used.
