Soil Sampling survey: Soil nutrients and isotope composition were measured in composite soil samples collected from the study sites (n=20) where microclimate is being monitored in the AWT. At each site, the authors collected five soil cores using an auger (~10cm deep) after removing leaf litter consisting of recognizable leaf fragments. Samples were bulked and homogenized for each site prior to analysis. Soil pH in H 2 O and in 0.01M CaCl 2 were measured on fresh soil using an ISFET pH pen (Model 24006 DeltaTrak). Samples were then oven-dried at ca 105℃ for up to 72h and powdered using a Benchtop Ring Mill. Soil analysis: Total soil elemental analysis was conducted using microwave-assisted acid digestion of the oven dried samples, followed by ionization detection using the Inductively Coupled Plasma-Atomic Emission Spectrometer (ICP-AES) at the Advanced Analytical Centre, JCU - Townsville. Soil carbon (%C) and nitrogen (%N) were measured using a Costech elemental analyser (EA) (Milan, Italy) fitted with a zero-blank auto-sampler at the Advanced Analytical Centre, JCU - Cairns. This was used to calculate the C:N ratio. The stable carbon and nitrogen isotope ratio (expressed as δ 13 C and δ 15 N) of the samples was measured using acThermoFinnigan Deltaplus XL isotope ratio mass spectrometer (ThermoFinnigan GmbH, Bremen, FRG), linked to the EA via a ConFlo III interface. Stable isotope results are reported as per mil (‰) deviations from the AIR reference standard scale for δ 15 N. Soil organic matter content (OMC) was calculated via loss of mass on ignition (360℃ for 2h).
