4. Nature of wind erosion

Wind erosion mostly occurs on loose and dry soil surfaces.

Suspension:
Saltation:
Surface Creep:

5. Factors affecting wind erosion and its control

WEQ: Wind Erosion Equation: E = f (I, K, C, L, V)

E: estimated annual erosion loss in tons per acre
(multiplies by 2.24 􀃆 mega grams per hectare)
f: function of ( )
I: erodibility factor (e.g., texture and aggregation)
K: surface roughness factor (e.g., ridges)
C: climate factor (Gardon City, KS = 1)
L: unsheltered length of field factor (how open is the field)
V: vegetative cover factor (cover type, density etc)
