摘要: Measurements of soil pH, resistance, cation exchange capacity and six macro- five micro-elemental concentrations were made over a 12-month period in disturbed (burnt Acacia saligna-infested) undisturbed habitats sand plain lowland fynbos community. Two null hypotheses tested, namely that there no differences chemical properties between (i) (ii) different seasons. A Friedman test was used to identify significant against seasons habitats. With respect acacia infestation, the first hypothesis rejected (P
