| Abstract | ||
| After the field investigation about native agricultural system and soil management practices in the region, nine sites were selected which were different in soil management systems. The morphology of the soils morphological was described and represented samples from every horizons were taken to study some physical and chemical properties Also analysis the available and total boron content in the soil was done. The results showed that:¬ 1-Studied soils at the region were classified within two orders Entisols and Aridisols. 2-Soil texture classes were varied horizontally and vertically within each pedon with decreasing in soil bulk density in Ap horizon for each pedon. 3- Available boron content in all soils was ranged from (0.1-4.5 mg B.kg-1 soil). Theelectrical conductivity and lime content were the main limited factors for available boron content. 4-The total boron content was ranged from (40-112 mg. B kg-1soil), The fine textured soils classes were relatively showed more contents than the coarse textured class soils. The electrical conductivity, lime content and Clay+Silt content were the main limited factors to the total boron content in the soil. 5- The pedological distribution of available and total boron in soil appeared to be depended on the management practices. | ||
