Tasmania island fire, Commonwealth of Australia, South Pacific Ocean

Tasmania Island Fire, Commonwealth Of Australia, South Pacific Ocean

Despite the presence of some Quaternary glaciation, Tasmania's soils are not more fertile than those of mainland Australia, largely because most are severely leached and the areas with driest climates (least leaching) were unaffected by glaciation or alluvia derived therefrom. Most soils on the Bass Strait Islands, the east coast and western Tasmania are very infertile spodosols or psamments, with some even less fertile "lateritic podzolic soils" in the latter region. Most of these lands are thus not used for agriculture, but there is much productive forestry—which remains one of the state's major industries.
On the north coast, apart from some relatively fertile alluvial soils used for fruit-growing, there are also deep red, easily workable soils known as "krasnozems" ("red land"). These soils are highly acidic and fix phosphate very effectively, but their extremely favourable physical properties make them extensively used for dairying, beef cattle and fodder crops.
The Midlands and the Lower Derwent present a different story from the rest of the state. Owing to a relatively dry climate and alkaline (mostly dolerite) parent material, these soils are relatively unleached and contain lime in the deeper subsoil. They are mostly classified as "prairie soils" or "brown earths" and bear some resemblance to the chernozems of Russia and North America, although they are much lower in available phosphorus and somewhat acidic in the surface levels. Their higher nutrient levels, however, allow them to support productive pasture, and large numbers of sheep are grazed in these regions. Some grain crops are also grown in the driest areas. In the alluvial areas of southeastern Tasmania, rich alluvial soils permit apples to be grown.
Tasmania became known as the "Apple Isle" because for many years it was one of the world's major apple producers. Apples are still grown in large numbers, particularly in southern Tasmania, and have the distinction of being the first approved by the Japanese government for import, due to their verifiable pest-free status.
