Good moisture availability is more important than inherent fertility in contributing to good growth, and many lowland sites with a history of forestry appear well-suited to SRF. Several eucalyptus species appear to grow well on alkaline soils, or thin soils over chalk. Growth on thin, free-draining and dry soils can be surprisingly good, provided there is reasonable moisture available to permit good establishment in the months after planting. Many species, notably the swamp gums, will grow on sites with periodically high water-tables, though their yield potential is unclear and they generally benefit from some drainage. There is little experience of growing eucalyptus on peaty soils, though it is likely that certain species will grow well on these provided there is some drainage.
As with any trees, there may be longer-term stability issues on soils that do not permit deep rooting due to impermeable subsoil or high water-tables.
