Fire is an important tool in the management of forest ecosystems. Although both prescribed and wildland fires are common in Turkey, few studies have addressed the influence of such disturbances on soil properties and root biomass dynamics. In this study, soil properties and root biomass responses to prescribed fire were investigated in 25-year-old corsican pine (Pinus nigra Arn.) stands in Kastamonu, Turkey. The standswere established byplanting and were subjected to prescribed burning in July, 2003. Soil respiration rates were determined every twomonthsusing soda-limemethod over a two- year period. Fine (0-2 mmdiameter) andsmall root(2-5 mmdiameter) biomasswere sampled approximately bimonthly usingsequentialcoring method. Mean daily soil respiration rangedfrom 0.65 to 2.19 g C m-2 d-1 among all sites. Soil respiration rates weresignificantly higher in burned sites than in controls. Soil respiration rates werecorrelatedsignificantly with soil moisture and soil temperature. Fine root biomasswassignificantly lower in burned sites than in control sites. Mean fine root biomass values were 4940 kg ha-1 for burned and 5450 kg ha-1 for control sites. Soil pH was significantly higher in burned sites than in control sites in 15-35 cm soil depth. Soil organic matter content did not differ significantly between control and burned sites. Our results indicate that, depending on site conditions, fire could be used successfully as a tool in the management of forest stands in the study area.
