1 Land use Very suitable  land classification. Fairly suitable  according to suitability factor. Not suitable  a particular crop. Land capability classification. The type of soil. Depth of soil. Texture. Land slope. Past erosion on the land.

2 Soil erosion by wind Wind erosion is more frequent when the mean annual rainfall is low. Major factor that affects soil erosion by wind are: climate Soil characteristics Vegetation climate: Rainfall affects soil moisture. Temperature humidity. Wind.

3 Wind characteristics that affects soil erosion.Duration. Turbulent of the wind (velocity). For any given soil condition the amount the amount of soil which will be blown depends on two factors: The wind velocity. The roughness of the soil surface. Soil: factors  soil texture.  density of soil particle and density of soil mass.  organic matter content.  soil moisture.

4 Vegetation:  height of vegetation.  density of cover. types of vegetation.  seasonal distribution of vegetation. Types of soil movement by wind Suspension. Saltation. Surface. creep

5 These three distinct types of movement usually simultaneouslyThese three distinct types of movement usually simultaneously. suspension  particle were carried about 1m above on the surface.( i.e. above 3ft) saltation  This is caused by the pressure of the wind on the soil particle and its collision with other particles. surface creep  This movement is mostly pronounced on the surface of the soil.
