BASE Contextual, Soil Physico-Chemical Data, Calperum Mallee SuperSite, Flood Plain Plot 08, 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.

为给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，本研究开展了土壤样品采集及理化属性分析工作。本研究从25 m×25 m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 cm与20~30 cm。其中8份样品采集自该样方各边的拐角及中点位置，剩余1份采集自样方中心。将每个深度的9份子样品混合后，每个样方可得到1份表层土壤样品与1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。
