Integral water capacity (IWC) and least limiting water range (LLWR): prediction using plant growth indices and soil properties

Rock size fragments reduction allow including their effect on water retention properties determined with a dew point potentiometer

“…The physically-based model Hydrus-1D (Šimůnek and van Genuchten, 2008) also needs PWP or a close value to parametrize the transpiration reduction function (Feddes, 1978) in the root water uptake submodel. Furthermore, PWP is a parameter in water availability indicators to plants, such as the least limiting water range and integral water capacity (Kazemi et al, 2020).…”
