描述----------Description----------
This dataset was collected on a line transect survey in gilgai territory in New South Wales, Australia. Gilgais are natural gentle depressions in otherwise flat land, and sometimes seem to be regularly distributed. The data collection was stimulated by the question: are these patterns reflected in soil properties? At each of 365 sampling locations on a linear grid of 4 meters spacing, samples were taken at depths 0-10 cm, 30-40 cm and 80-90 cm below the surface. pH, electrical conductivity and chloride content were measured on a 1:5 soil:water extract from each sample.
此数据集收集了上在gilgai,澳大利亚新南威尔士州境内的样线调查。 gilgais在原本平坦的土地自然柔和的凹陷,有时似乎要定期分布。问题:数据收集,刺激了这些模式反映在土壤性质?在365个采样地点的4米间距的线性电网,每个样品进行了深度0-10厘米,地表以下30-40厘米和80-90厘米。上1:5土:水从每个样品提取物,pH值,电导率和氯化物含量的测定。
