In this experiment, the effects of different organic materials addition on some physical and chemical properties of soil have been studied by the application of four different sources of organic material to soil. The study was carried out under the greenhouse conditions as pot experiment. Organic materials were applied to soil in three different doses, being pigeon manure, vermicompost, humic acid and barnyard manure.According to the results of research into soil types and doses of organic material of some physical and chemical properties of soil has been a different effect on. A month 3 incubation period at the end, the different origin of organic materials of soil organic matter content (OM), cation exchange capacity (CEC), soil reaction (pH), electrical conductivity (E.C),trace elements, total nitrogen and phosphorus content of some physical and chemical properties on the effects of different levels occurred. As a result of the study, it showed that the soil regularly and efficiently with the use of organic materials with different origins could be able to improve the physical and chemical properties.
