water uptake.xlsx

Deuterium injections were used to describe the proportion of tree or grass roots with soil depth. These active root distributions were used with climate and soils data in the Hydrus 1D model to simulate water uptake by a theoretical plant canopy to estimate the effect of vertical root 'shape' on water uptake. Values represent the mm of soil water absorbed by tree or grass roots across two growing seasons. Data provided for four study sites in Kruger Park that represent a factorial combination of mesic (750 mm precipitation) and xeric (450 mm precipitation) savanna.
