water uptake ratio.xlsx

The ratio of water absorbed by a theoretical plant canopy with a tree rooting distribution or a grass rooting distribution. The ratio is the ratio of total water absorbed across three growing seasons. The ratio was calculated for soils where 10%, 50% or 90% of the roots in the soil had a 'tree-shaped' rooting distribution. Results are shown for four sites in Kruger National Park that represent a two-way factorial combination of mesic (750 mm precipitation), dry (450 mm precipitation), sand, or clay soil conditions.
