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.

为支撑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/）的研究需求，本研究开展了土壤样品采集及其理化属性分析工作，以提供相关背景数据。本次采样覆盖25米×25米的样方，设置两层采样深度：0–10厘米与20–30厘米，共采集9份独立土壤样品。其中8份样品采集自该样方各边的端点与中点，剩余1份样品采集自样方中心。针对每个深度层，将9份亚样进行混合，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。用于理化分析的土壤样品经风干处理后，被运送至澳大利亚珀斯的CSBP实验室完成检测。
