We assessed crop cultivation effect on soil quality index (SQI) in rangelands. Organic carbon and salinity were the key indicators of soil changes and SQ. Assessing SQI allowed a better discrimination between rangeland and cropland sites. Long-term cultivation and disturbance in native rangelands degraded severely SQ. Cropland soils functioned at 52–64% of the potential capacity of rangelands soils.
