Abstract Cowpeas [Vigna unguiculate (L) Walp] as a summer cover crop have the potential to provide N to a cool‐season crop. The objectives of this study were to evaluate two cowpea cultivars grown as a cover crop to supply N for forage rye (Secale

Summary The alternation of pluvial and non-pluvial periods during the Tertiary-Quaternary resulted in periodicity of soil formation and landscape development. Soils were formed during the pluvial periods, when the landscape was protected from erosion

Summary Remnants occur in arid Australia of a formerly extensive land surface on which deep lateritic soils were developed. The lateritic profile, which contained silicified layers in the upper portion of the pallid zone, was subsequently truncated a

Summary The stony tableland soils which are paleosols of Quaternary age have a clay profile, high proportion of exchangeable sodium, strong salinity, large amounts of stone in the upper few inches of the profile, a surface stone pavement, low carbona

Summary Seven soil regions, each of which is dominated by soils belonging to one or two great soil groups, are defined and mapped. The outstanding feature is the presence of a variety of soils with widely differing characteristics. The soils are deep

Summary Two soil layers of Quaternary age are identified. The distribution of the layers, the older of which is buried in some areas and exposed in others, is discussed. The soils in each layer are developed on parent materials of predominantly wind-

The Cainozoic history of the Lake Eyre region opened with a period of deep weathering during which many of the older rocks were extensively kaolinized. Following erosion and later deposition of a thin sheet of Tertiary fluviatile deposits, a period o
