cles.
             POSSIBLE THRESHOLDS: Sediment erosion and transport takes place within a specific range of wind speeds, depending on grain size, degree of cementation and compaction, moisture content, and vegetation cover.
             Differential erosion by wind in the past may be detected through study of buried soil horizons developed on ancient erosional surfaces, which formed during dry (wind erosion) to wet (soil formation) climatic cycles.
             Raindrops can be a major problem for farmers when they strike bare soil. With an impact of up to 30 mph, rain washes out seed and splashes soil into the air. If the fields are on a slope the soil is splashed downhill which c
