AbstractEight Pedones distributed in four regions of central Iraq are chosen. Pedone (1) represents Port soil and seven Pedones represent palm groves soils, to study the genesis and composition of the soils with large old palm groves in areas of central Iraq .The Pedones are revealed and described morphologically and obtained the excited soil samples from each horizon for the purpose of conducting physical and chemical analyses. This study shows a discrepancy in the morphological characteristics of the comparison Pedone with palm groves Pedones. It is noted that the existence of diversity in the distribution of volumes of soil minutes . The results show that in some palm groves Pedones that the distribution of total and active clay particle showed certain pattern which represents an increase with the depth as compared with the soil of comparison Pedone that does not show any pattern of distribution, and that due to the role of the root system Corynebacterium of palm trees. That helped in the transmission of the total and active clay particle .The results also refer to the movement of total metals and active carbonate. The results of the chemical characteristics also showed that the degree of soil reaction to that of the comparison Pedone is high as compared with palm groves Pedones and generally ranged from the valuesof the pH between (6.70-8.10) and decline is observed in the proportion of electrical conductivity prospects of palm trees Pedones ranging between (0.45-40.5), while the values of calcium carbonate are ranged (159-350) and the active carbonate are (36-85).
