DETERMINING SOIL CAPABILITY TO WIND EROSION AND ITS RELATIONSHIP TO SOME OF THE CHARACTERISTICS OF SOIL IN NORTH OF SAQLAWIYAH

Abstract

The study area was chosen within the boundaries of the Saqlawiyah sub-district،between longitudes 43o39-30=- 43o42-30= and the latitudes33o25-0= -33o30-20= the determining of the Capability of the soil to wind erosion and its relationship to some of the characteristics of soil in North of Saqlawiyah. After specifying the required information،six sites were chosen to represent the study area،where five samples were taken from different points for each site in the study area based on the study sites were determined using a GPS device. The value of the soil susceptibility index to wind erosion was calculated for each sire،and the results showed that the highest value of the Soil Susceptibility Handbook was in desert soils with sandy texture،amounting to 320 Mg H-1 Whereas،the value of soil erosion index in cultivated soils decreased to 55 Mg H-1 The highest value of the soil receptivity index for erosion is 320.0 Mg H-1 at the clay content of 40 g Kg-1،and the lowest value of the soil erosion index was 55.0 Mg H-1 at clay content 168 g KG-1 In cultivated soils،The values of the index of soil susceptibility to wind erosion ranged in general between 55 -320 Mg H-1where the highest value of the index of soil susceptibility to wind erosion was 320.0 Mg H-1in desert soils،while the lowest value of the index of soil susceptibility to wind erosion was 55.0 Mg H-1in cultivated exploited soils.
