Abstract: 
Dasht-e-Room is located in the south-west of Yassoj (capital of the province). It has an elevation of 2090 m above mean sea level with an annual precipitation of 1029 mm. In this study, the influence of climatic indices and some soil properties on grass covering development and formation and genesis of mollic epipedon were investigated. To answer the question of "which soil properties and climatic indices are more effective on the mollic organic carbon content of the topsoil and consequently on the genesis of the mollic epipedon?" many factors were investigated. In this study, a set of soil properties and climatic indices were identified. Amount and distribution of precipitation results in extenuation of grass cover. High elevation above mean sea level of this area (through increasing the precipitation and decreasing the air temperature), causes significant increase in soil organic matter. Clay content by forming organic and inorganic complexes and adsorption of humic substances helps in retention of organic matter in soil. Ali these indices are important in fulfilling the requirements for mollic epipedon in soil surface horizon.
