The Pullman soil used to simulate sorghum growth and yield extends to a depth of 1.83 m with unavailable water contents, hashed area, varying from 0.11 to 0.24 m3 m–3 and available water contents, white area, that range from 0.26 to 0.33 m3 m–3 (Howell et al., 1989; Steiner, 1989). Potential water-filled pore space was calculated from measured bulk density assuming 2.65 Mg m–3 particle density.
