Physicochemical soil properties were derived from each soil core(N = 60) of 5 times replicated 12 Kilimanjaro ecosystems. Soil pH was measured from 10 g air-dried soil samples dissolved in 25 ml 0.01 molar CaCl2 solution with a SenTix 61 electronic pH-meter (WTW GmbH, Weilheim, Germany). Soil organic carbon (SOC) and total nitrogen (Ntot) contents were determined using an elemental analyzer(Elementar Analysensysteme, Hanau, Germany; measured by University of Hohenheim) according to DIN ISO 13878, 10694, and 15178. Soil texture (2 mm.
