Estimating Wind-Erodible Materials on Newly Crusted Soils

A 16-year record of eolian dust in Southern Nevada and California, USA: Controls on dust generation and accumulation

“…Dust entrainment depends chiefly on (1) daily and seasonal meteorological conditions that can generate turbulent winds capable of raising dust (Goudie and Middleton, 1992); (2) the threshold friction velocities of surface materials (Gillette et al, 1982;Gillette and Sinclair, 1990), which are mainly dependent on particle size and moisture content and also on clay mineralogy and degree of cementation or crusting of the source (Potter, 1990); and (3) the type and amount of vegetation (Musick and Gillette, 1990;Musick, 1999). These three parameters fluctuate both annually and seasonally.…”

Spatial pattern and heterogeneity of soil properties in sand dunes under grazing and restoration in Horqin Sandy Land, Northern China

“…Our results show that continuous grazing resulted in a decrease in soil organic C, total N and very fine sand content. Commonly, sandy soils are less resistant to erosion by wind than (undisturbed) finer textured soils (Lopez et al, 2000;Potter, 1990). Wind erosion can cause a loss of soil fine particles, especially very fine sand (0.1-0.05 mm), the most erodible fraction , and increase soil coarseness (Gomes et al, 2003).…”

Effects of aeolian deposition on soil properties and crop growth in sandy soils of northern China

“…Research has confirmed that soil erodibility is affected by inherent properties of the soil (Liu et al, 2003), wind speed (Lopez et al, 2000) and ground-surface cover (Li et al, 2004). Commonly, sandy soils are less resistant to erosion by wind than (undisturbed) finer-textured soils (Potter, 1990;Lopez et al, 2000). Soil wind erosion is an important process that affects both the surface features and the biological potential of soils (Marticorena et al, 1997), and has been identified as a serious threat to sustainable crop production (Lal, 1998).…”
