Effects of Irrigation Water with Different Salt Concentrations and SAR Values on Soil Salinisation and Sodification

BACKGROUND. Most soils irrigated with brackish wa-ter are subject to salinisation or alkalisation, which cause a reduction in soil fertility and the formation of saline-alkaline soils in the medium or long-term. To further contribute to the knowledge on these top-ics, a study was undertaken on the salinisation and sodification of soils irrigated by waters with different salt concentrations and sodic levels, within a collab-orative research project dealing with the effect of ir-rigation with saline-sodic waters on the chemical, hy-drological, mechanical and agronomic aspects, under laboratory and field conditions. METHODS. Two types of clay loam soils were tested for two consecutive years. They were packed in cylin
