Webthe longer aggregates remain on the soil surface, protecting the more erodible fraction. Therefore, the amount, stability, and placement of soil aggregates on the soil surface exert major influences on a soil's susceptibility to wind erosion. The purpose of this paper is to review the current state WebThe erodible fraction (EF) of soil (soil aggregates and particles <0.84 mm) is one of the basic factors according to which the susceptibility of soil to wind erosion can be assessed.

WebDec 1, 2024 · The erodible fraction (0.85–1.0 mm) decreased linearly with increase in soil hardness (R 2 > 0.9), OC, CaCO 3.

WebSoils are placed into wind erodibility groups on the basis of the properties of the soil surface layer. Subpart B, Exhibits, Section 618.95 lists the wind erodibility index assigned to the wind erodibility groups. The wind erodibility index values are assigned because the dry soil aggregates are very use-dependent on crop management factors. WebIn all soils containing erodible and nonerodible fi.act,ions the amount of soil removcd under an erosive wind force was limited by the height and the number of noncrodible fractions that were exposed on the surface by the wind.
