Effects of Forest Fire on Soil Chemical Properties in the Guilan Province (Case Study: Shafaroud Region-Pilambara)

The aim of this study was to evaluate the effect of fire on some soil chemical properties (pH, EC, %N, %OC, P, K, CEC) in the plantation of loblolly pine (pinus teada) in Shafaroud region (Series 19 Pilembera). in this study, 10 soil samples for each area (a total of 20 samples) randomly picked up and transferred to the soil laboratory. In order to evaluate and compare the results of the parameters measured in the fire area and without fire test nonpaired T-test was used. The results showed that the fire was increasing (pH, CEC, EC, P and %N) and reducing (K, %OC and C/N) soil. The fire on the parameters pH, CEC, EC, %OC, C/N at 95 percent was significant effect and on the parameters P, K, %N at 95 had no significant effect.
