Soil water potential data take on 1 to 3 hour intervals from November 2007 to June 2013 in the Nkuhlu exclosure near Pretorioskop, Kruger National Park, South Africa. Campbell Scientific 229 heat dissipation sensors were calibrated to the local soil and used at soil depths of 5, 10, 20, 50, 75, 120 and 150 cm depths. Sensors were all located within 100m of each other but one vertical array was located under a closed tree canopy (tree), one under a grass canopy (grass) and one under a mixture of grass and tree cover. Soils are granite-derived sands.
