Differences in the Efficiency of the Vertical Transfer of Windblown Sediment over Different Ploughed Surfaces during Wind Erosion Events

Airborne sediment fluxes were measured in southern Tunisia on two experimental plots tilled with a moldboard and tiller plough, respectively, during five wind erosion events of different intensities. The sampled both using mast equipped seven sand traps positioned between ≈10 120 cm height. windblown the 0–100 layer about eight times higher plot plough compared to due efficiencies trapping saltating particles furrow, depending ridges characteristics. On plots, larger depleted samplers proportions soil from which they derived. When examining flux 30–100 layer, we observed that efficiency vertical transfer was twice than one. This implies fraction mobilized by can be transported over long distances case surface ploughed moldboard. result could reduce part benefit instead regarding loss erosion.
