The effect of fire was investigated on some soil chemical properties of forest area of Baghe Shadi Herat- Yazd Province. To perform the experiment, 18 profiles of soil in control area and 7 profiles from each of burned areas were dug and samples of two depth (0-15 and 15-30) in total of 64 samples were collected. Results showed effect of the area was significant in organic matter and carbon percentage, P and N. The average amount of carbon, organic matter and N in burned areas were significantly more than control. The average amount of carbon, organic matter and N in control were equal to 0,76, 1.31 and 0.82 and in burned area were equal to 1.35, 2.4 and 1.03 respectively. There are significant differences in organic matter and carbon percentage, P and N between two depths of 0-15 and 15-30 and the measured characters were high in 0-15 compared to 15-30. It is concluded that fire can positively affect in increasing some element such as the average amount of carbon, organic matter and N and therefor proposed that other studies such as fauna and flora of soil, erosion possibility and ecological and forestry changes would be done at the same time.
