It is located northwest of Karbala Province, Iraq. The aim of study was to calculate the soil organic carbon stock (SOCstock) using the Food and Agriculture Organization equation [1]. Also, to evaluate the state of change in vegetation cover based on the Normalized Difference Vegetation Index (NDVI). The 30 soil samples were taken from the study site. Some general soil characteristics were estimated based on common laboratory analysis methods for soil depth 0-30 cm. The results showed that there is a noticeable variation in the stock of organic carbon in desert soil under the effects of vegetation cover, land use and the temporal changes to which the amounts of organic carbon stock are exposed under the agricultural management method. It was led to the accumulation of organic waste through the variation and difference in soil characteristics and the impact of agricultural practices. The results estimated that there was a significant effect on the content of the organic carbon stock in these lands. These results indicated that the lowest organic carbon stock values were recorded 7.18-31.56 tons/ha⁻1 in the sample sites (2, 3, 4, 10, 11, 12, 13, 17, 18, 19, 20, 21, 23, 24, 25, 26, 27, 28, 29, 30), respectively. The highest value was 32.13-57.66 tons/ha⁻1 at sites (1, 6, 7, 8, 9, 14, 15, 16, 22), respectively. A high significant value was found in palm cultivation sites and its values were recorded at 57.66, 56.76, 51.90 tons/ha⁻1, respectively, for the site (8, 9, 22).
