    Determination of short-term effects of wild fire on soil properties and nitrogen mineralization in Turkish pine (Pinus brutia ten.) in Turkey (the case of sariçiçek sub-district directorate)
    (Corvinus University of Budapest, 2020) Küçük, Mehmet; Kahveci, U.
    Forest fires are one of the factors that play an important role in both global warming and nutrient accumulation in soils. The level of these effects varies according to the severity and intensity of the fire. This study was conducted to determine the one-year effects of fire on soil properties and nitrogen mineralization in Turkish Pine stands exposed to low-intensity surface fire that naturally occurred at the Sarıçiçek region the Vezirköprü district of Samsun province in 2014, in Turkey. To this end, six sampling areas were selected from both burned and unburned (control) areas in the sections. Soil samples were taken from a depth of 0-5 cm and 5-10 cm. Nitrogen mineralization was determined by the land incubation in 3 periods (April-July-October, 2014) on-site holding method. Among soil properties, texture, pH, organic matter, total nitrogen, bulk density and carbon (C) / nitrogen (N) ratio analyses were assessed. As a conclusion, it was observed that significant differences occurred in soil properties and nitrogen mineralization temporarily. Average nitrogen mineralization at a depth of 0-10 cm over the one-year period was found to be 23.56 kg /ha in the burned areas and 25.2 kg/ha in the control areas. As a result of the study, it was concluded that the fire was more effective, especially at a depth of 0-5 cm in regards to changing the soil properties. Nitrogen mineralization at a depth of 0-5 cm was greater in the burned areas compared to controls. It was determined that especially low-intensity fires were not effective toward the lower depth levels.
