The agricultural soil that widely is cultivated by wheat crops in the main 30 districts in Badinan province of Duhok governorate in Iraqi Kurdistan region was analyzed for the heavy metals spatial distribution, and there environmental and agricultural impacts for human being and plants. The result revealed that the maximum range of Nickel was not exceeding 400 mg.kg−1 which is safe according to USA standard. In spite of high total Iron in Badinan soils that are aerobic and have high pH, Fe is readily oxidized, and converted to insoluble ferric oxides to be unavailable for plants. Lead and Cobalt are very low in all 30 sectors of Badinan province except lead in Duhok center exceeds 100 mg.kg−1 as it affected greatly by pollution. Cupper content in soil samples is an adequate of most plants cultivation and lie within the permissible limits. Cromium heavy metal concentered along Zakho district to the Duhok city, although it not exceeds hazardous ranges. The Zinc concentration in Badinan soils is between 40 and 120 mg.kg−1 and locates in sufficiency range of most crop and vegetables requirements. Cadmiumd fortunately, is very low and not exceeds 0.75 mg.kg−1 in in all sectors in Badinan. Badinan soils contain high amounts of Manganese 350 to 650 mg.kg−1 , but the available parts are very low as it bind firmly to soil colloidal system. Badinan soils are rich with Aluminum but locate within permissible limits and called as an innocent compound due to its rare toxic cases for human being.
