•Soil profile had a considerable variation of soil properties and SQI with depth and within horizons.•Cubist model can be used to predict SQI.•The grid soil sampling can be used to characterize soil properties and SQI in soil profile wall.•Combined Vis-NIR and pXRF spectra had better prediction perf...
