BASE Contextual, Soil Physico-Chemical Data, Calperum Mallee SuperSite, Core 1 ha, 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/). Nine discrete soil samples 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 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.

本研究开展土壤样品采集及理化性质分析工作，旨在为澳大利亚土壤环境生物群系（Biomes of Australian Soil Environments, BASE）土壤微生物多样性项目（http://www.bioplatforms.com/soil-biodiversity/）提供背景数据。本研究从25米×25米的样方中采集9份独立土壤样品，采样深度分为两个区间：0~10厘米与20~30厘米。其中8份样品采集自该样方各边的拐角与中点位置，剩余1份采集自样方中心。针对每个深度区间，将采集到的9份亚样品进行混合，最终每个样方得到一份表层土壤样品与一份深层土壤样品。用于理化性质分析的样品经风干处理后，被运送至澳大利亚珀斯的CSBP实验室进行相关检测。
