Comparative fit of seven models: (a) clay loam (Misan soil, 23–47 cm), (b) silty clay loam (Wunkyo soil, 25–65 cm), (c) silty clay (Seotan soil, 84–100 cm), and (d) clay (Bankok soil, 0–12 cm). Obs. = observed, SL = simple lognormal model, SC = Shiozawa and Campbell model, Gomp. = Gompertz model, ORL = offset-renormalized lognormal model, ONL = offset-nonrenormalized lognormal model, and Fred. = Fredlund model.
