Prediction of the soil water retention curve for structured soil from saturation to oven-dryness

摘要

Highlights• Is a new approach to modelling the soil water retention (SWR) curve applicable to structured soil?• The model accurately predicts the full SWR curve with an RMSE of 0.04 cm3 cm−3.• Prediction accuracy of the wet part of the SWR curve was sensitive to variation in bulk density.• The pF at zero water content, which affects the prediction of dry SWR, ranged from 6.65 to 7.10.
