Simulations of the dust cycle and its interactions with the changing Earth system are hindered by the empirical nature of dust emission parameterizations in weather and climate models. Here we take a step towards improving dust cycle simulations by u

A theory is developed to describe the dependence upon roughness density of the threshold friction velocity ratio Rt, the ratio of the threshold friction velocity of an erodible surface without roughness to that of the surface with nonerodible roughne

The Role of Trees in Sustainable Agriculture ISBN: 9789401048095
The purpose of this review is to examine the current knowledge of the role of trees in providing shelter for pastures, crops, and livestock, for controlling erosion of soils and improving productivity and sustainability of agricultural production in

A portable wind erosion tunnel has been used to measure the wind erodibility of nine soil types with a range of surface textures under two treatments (bare uncultivated and bare cultivated) in western New South Wales. The erodibility has been charact

Lupins are frequently the preferred legume species used in dryland crop rotations on light sandy soil types. These soils are prone to erode and the probability of sandblasting is increased if sown to lupins because of their slow growth and low vegeta

We investigated the effects of 2 different grazing regimes on the surface soil properties of a dunefield land system in the semi-arid woodlands of eastern Australia. Sandy siliceous, thermic Xeric Haplargids (Siliceous Sands, Uc1·23) occur on the sa
