CC BY 4.0 License. 25 Abstract 26 The Republic of Azerbaijan has suffered from low agricultural productivity caused by soil salinization and 27 erosion, and limited and insufficient soil data are available for economic and political reasons. In this study, soil 28 elemental composition and heavy metal levels were assessed by comparing the results of XRF and ICP-OES analyses 29 for the first time. Leachability assessment and spatial variability analysis were conducted to understand the soil 30 salinization properties, and 632 surface soil samples categorized as agricultural (Ag) or salt-affected (SA) soils from 31 the Mugan Plain were collected and analyzed.
