Soil organic matter (SOM) is a key factor in maintaining soil quality. The main aim of this research was to investigate the distribution of soil organic matter in the coastal region of Syria. For this purpose, thirty-one representative soil profiles were prepared in Latakia governorate from three different land types according to usage (i.e. forest land, rangeland, and agricultural land). Soil samples were collected from the top layer, then analyzed. Results showed that the total organic matter (TOM%), as well as soil properties, varied between the studied agroecosystems. Notably, the average recorded TOM percentages were 5.34%, 4.38%, and 4.07% in forest land, rangeland, and agricultural land respectively. Additionally, matrix correlation between different soil aspects indicated a positive significant (p <0.05) correlation between clay content and Cation-exchange capacity (CEC), and between CEC and TOM in forest land cover. On the other hand, agricultural land showed a positive significant (p <0.05) correlation between water content and each of CEC and clay content, and between clay content and CEC.
