Land resource areas

The Condamine Catchment contains some of the most fertile soils in the world and is one of the most productive agricultural areas in Australia.

A Land Resource Area is an area of land with a particular combination of soils, geological material, topography and vegetation. There are 12 major Land Resource Areas in the Catchment:

1.    Recent Alluvial Plains - mainly between Leyburn and Warra, suitable for dryland and some irrigated cropping.
2.    Poplar Box Solodic Plains - originating near Millmerran and along major creeks, suitable for pastures and grazing.
3.    Cypress Pine Sand Plains - flat to gently undulating sand plains, suitable for grazing and some dryland cropping
4.    Brigalow Plains - occurring in large sheets between Dalby, Chinchilla and Glenmorgan, suitable for grazing and moderate dryland cropping.
5.    Brigalow Rises - suitable for dryland cropping and grazing.
6.    Rolling Downs/Walloons - undulating plains and rises west of Chinchilla, suitable for dryland cropping and grazing.
7.    Ironbark Solodics - occurring throughout the Catchment, west of Dalby, in the north west of the Catchment and to the south west of Millmerran, suitable for grazing
8.    Poplar Box Solodics - found along the edges of Brigalow Plains, suitable for grazing.
9.    Marburg Sandstone Hills - occurring in the uplands of the Catchment, on crests, plateaux and rock outcrops, suitable for limited grazing
10.    Basaltic Uplands - found in the east of the Catchment, suitable for cropping, horticulture and grazing
11.    Granite Hills - extensive area of rocky ridges and outcrops occurring in the headwaters of the Catchment, suitable for grazing
12.    Traprock Hills - areas of rocky ridges occurring in the headwaters of the Catchment, suitable for grazing
