The codes of the different soil samples are: LT-S, Lonely tree composite rhizospheric soil; LT-CS, Lonely tree non-rhizospheric control soil; Ps-Bp, Planting Soil before planting V. pachyceras seedlings (non-rhizospheric crude commercial soil mix); Ps-Ap-LTA and Ps-Ap-LTB, Planting Soil after planting Lonely Tree seedlings (rhizospheric commercial soil mix of local V. pachyceras); Ps-Ap-SA, Planting Soil after planting Saudi Arabia V. pachyceras seedlings (rhizospheric commercial soil mix of non-local V. pachyceras).
