All alive organisms of soil depend on organic matters for energy and nutrients. So, one of the properties of fertile soils is content of organic matters. This research was conducted in agricultural lands, rangelands, gentle and steep slope rain fed lands in three regions (Kermanshah، Paveh، Javanroud) of Kermanshah province to analyze the content of organic matter in three soil layers (0-30، 30-60، 60-90 cm) based on split plots as a completely randomized blocks experimental design. The results of organic matter analysis for 81 soil samples showed that there is a significant difference between agricultural treatment and soil layers (99%). Also comparison of different treatments using Duncan analysis showed that the highest rate of organic matter is related to Kermanshah while the lowest amount was obtained in Paveh, more over rangelands had the highest amount of organic matter but the steep slope rain feds had the lowest organic matter content the highest content of organic matter was obtained from topsoil but the lowest one is related to the deeper layers of soil in gentle slope rain fed lands.
