Abstract

The FIRE as one of the ecological factors has positive or negative effects on ECOSYSTEMs components. Therefore, this study was evaluated the effects of FIRE on some SOIL physico-chemical properties in winter rangelands of BEHSHAHR. Two burned sites were selected in rangelands and those rangelands which were changed to wheat and barley farmlands with two control areas (unburned) in each of them. The SOIL sampling was performed in three transects (100m) with ten sampling points in random-systematic method (total 30 samples in each area). SOIL samples were collected from 0-15cm depth. The SOIL physico-chemical properties such as bulk density, moisture, texture, potassium, phosphorus, nitrogen, calcium carbonate, organic carbon, acidity and electrical conductivity were measured in laboratory. Finally, the data were analyzed using paired t-Test in SPSS19 software. The results showed that the FIRE in rangelands had significant effects on moisture (P£ 0.01) and organic carbon (P£ 0.05) decrease but P (P£ 0.01), K, EC and pH (P£ 0.05) have been increased. While K significantly increased (P£ 0.05) and moisture decreased (P£ 0.01) in changed rangelands. Generally, the results showed that SOIL chemical characteristics had clear and more specific reaction against the FIRE in natural ECOSYSTEMs in comparison to changed rangelands. Also according to the results, it is necessary to manage intensity and time of FIRE to control the following effects of FIRE.
