Soils of Rosebank Research Station, Longreach, Queensland

Abstract

The soils of Rosebank Research Station, Longreach are described and mapped at 1:25 000 scale. The report draws together information on the climate, landform, geology and vegetation of the region. The morphology and distribution of the soils are discussed with reference to usage and management considerations. The survey shows the property comprises 70% rolling downs with minor gidgee and boree communities. The remaining portions are associated with the drainage lines of Elibank and Wellshot creeks. Soils of the rolling downs are moderately deep cracking clays with strongly self-mulching surfaces. Colluvial soils adjoin the streamchannels. The channel benches, backplains and braided drainage depressions are a complex of cracking and non cracking clays and duplex soils. The soils generally are
alkaline and calcareous.
