BASE Contextual, Soil Physico-Chemical Data, Great Western Woodlands SuperSite, Core 1 ha, Gimlet, Redgum, Blackbutt plots 2013

Soil collection and analysis of chemical and physical attributes was carried out to provide contextual data for the Biomes of Australian Soil Environments (BASE) soil microbial diversity project (http://www.bioplatforms.com/soil-biodiversity/). At each site, nine discrete soil samples were collected from a 25 m x 25 m quadrat, sampled at two depth ranges (0 – 10cm and 20 – 30cm). Eight samples were taken at the corners and mid-points of the 25 m x 25m sides of the quadrat, with a further sample taken at the centre. The nine subsamples were combined for each depth, to return a single surface and deeper soil sample per quadrat. Samples for chemical and physical analysis were air-dried and transported to CSBP laboratories, Perth, Australia.
