Abstract/Description: | Pedotransfer functions (PTFs) for estimation of soil water retention at field capacity (θFC, -33 kPa) and permanent wilting point (θPWP, -1500 kPa) were developed under three soil categories (<20%, 20-40% and >40% clay) through linear, log-linear and stepwise-regression (SR) approach, using particle size distribution and bulk density data. Under <20% clay, the log-linear model was better than other models in predicting θFC, whereas SR model was better for predicting θPWP. Under 20-40% clay category, all the three approaches predicted θFC with equal efficiency, while SR was superior for θPWP. The log-linear models performed better in predicting both the θFC and θPWP with >40% soil clay. |
