Phosphorus Availability and the Nutrient and Carbon Content of Mulga Understorey Species: Comparisons with Other Vegetation Types in Sub-tropical, Semi-arid Rangelands in the Pilbara, Western Australia

摘要

Phosphorus addition increased mineral concentrations and improved the nutrient status of the perennial shrub Ptilotus obovatus (Cotton bush) and the ephemeral only after summer rain. In the ephemeral and the perennial species, most nutrients (N, K, Ca, Mg
