Wind erodibility of soil (WE) is a prime factor for the predication, assessment and mapping of wind erosion. Thus, this study was undertaken to generate wind erodibility data, their relationship to relevant soil properties and plotting them in a map for North Kordufan State. Surface soil samples (0-3cm) were collected from fifty farms(beldat), scattered all over the State, and non-erodible soil particles (NEP > 0.84 mm), wind erodibility and relevant physical and chemical soil properties were determined using standard procedures. The mean clay, silt and sand percentages ranged from 3.0 to 6.9, 0.3 to 6.4 and 90.0 to 96.6, respectively. The textures of the studied soil samples were sand with mean sand percentage equal to 93. The mean percentage of NEP ranged from 1.4 to 24.3, with a mean of 13.3 and the overall mean coefficient of variation (CV) for all samples was 5.6%. The NEP was low because of the lack of appropriate cementing agents. The mean percentage of WE ranged from 186.7 to 641 tons/ha, with a mean of 310.2 tons/ha. The variation in WE may be due to variation in the sand size fractions. For North Kordufan State, WE can be predicted from knowledge of NEP according the following equation: WE (ton/ha) = -148.3 Ln (NEP) + 658.83 (r2 = 0.9894) This equation accounts for 99% of the variation of WE. NEP and WE did not correlate with primary soil particles or their ratios due to lack of variation in the texture of the studied soil sample
