    EFFECTS OF LOGGING RESIDUES AND SKID ROADS ON LITTER DECOMPOSITION RATE AND NUTRIENT RELEASE OF BLACK PINE (Pinus nigra Arnold) AND SCOTS PINE (Pinus sylvestris L.)
    (Croatian Forestry Soc, 2022) Enez, Korhan; Savaci, Gamze; Sariyildiz, Temel
    Needle litter decomposition rate and nutrient releases of pure stands of black pine and Scots pine under the three different micro-ecologic sites (skidding road, the logging residues and mineral topsoil) and the control site (nonharvesting site) were studied. The needle litters of Black pine and Scots pine were initially analysed for total carbon and nutrient concentrations (N, P, K, Ca, S, Mg, Mn, and Fe). The litter decomposition experiment using the litterbags method was carried out in the field for 18 months. The Scots pine needle litters decayed faster than the black pine litters. Both the Scots pine and Black pine needle litters showed higher mean mass losses under the mineral topsoil and the logging residues than under the skid road and the control site.

    SLOPE EFFECT ON THE SEDIMENT PRODUCTION OF FOREST ROADS IN KASTAMONU OF TURKEY
    (Parlar Scientific Publications (P S P), 2018) Erdem, Ramazan; Enez, Korhan; Demir, Murat; Sarıyıldız, Temel
    The purpose of this study was to determine actual amount of sediment productions of paved (PFR) and unpaved (UPFR) forest roads at different longitudinal slope groups (2-4%, 4-6%, 6-8%, 8-12%) were compared to undisturbed forest land (UA) in Kastamonu-Arac of Turkey with the help of the sediment traps. It was determinated that the total annual amount of sediments from the UPFR was found to be significantly higher than the amounts of sediments from the PFR and UA according to the slope groups. There were statistically significant differences between the amounts of sedimentation from the forest roads sides and within the UA (0.05
