Association of collection records of <i>Chloris truncata</i> with soil types in Australia [58] found within the projected area of climate suitability (EI>0).

X2 test of association = 798.3, 8 df, P<0.001. Soils with fewer than 5 observed records were combined under “Grouped minor soils” (black duplex, grey duplex, non-cracking clays, bare rock, lakes, organic & no data).卡方关联性检验（X2 test of association）的检验统计量为798.3，自由度为8，P值小于0.001。观测记录数不足5条的土壤被归入"分组次要土壤（Grouped minor soils）"类别，该类别涵盖黑色复层土、灰色复层土、非开裂黏土、裸岩、湖泊、有机土壤及无数据样本。
