| Abstract | ||
| The study was collected in nine soil samples from three different regions in Ninavah and Duhok Governorates including (Makhmor، Al-Kosh، and Zakho) those areas where the varied climatic conditions (annual temperature and rainfall). The aim of the study is to identify the disparity in the quantities of elements (Co, Ni,Cu, Pb,Zn, Zr). The field work included soil profiles description and soil sample collections from three depths (0 – 20, 20 - 40 and 40 – 60 cm). Soil routine analysis had been done on each sample beside chemical analysis by using (XRF) instrument. The results showed that there is a difference in the quantities studied elements and walk elements of behavior similar to where the highest values in the soil of Zakho and gradually fell in soil Al-Kosh and lowest values were in the soil of Makhmor for each elements. This is a pointer to the difference and disparity in weathering degrees and leaching in the study areas because of the disparity in temperature and in the amount of rainfall annually. The pedogenic distribution pattern of each element during the depths within pedon was irregular and cause irregular due to the characteristics of contrast soils depths within the same pedon and to the circumstances of each pedon alone in particle size distribution of the minutes of soil and topographic and climatic conditions for rainfall as well as the role of weathering of parent material calcareous، where all this is reflected on the distribution of the element during the depths of pedon per soils study. The results of enrichment factor (EF) showed that lowest values were in the soil of Makhmor and highest values in the soil of Zakho. | ||
