Tarım traktörleriyle bölmeden çıkarmada meydana gelen toprak ve fidan zararlarının araştırılması

Aims of the study, environmental problems are determined at logs extracting with farm tractors skidding on skid trail and the soil and seedling damages prevention possibility are investigated. This direction aims to; the harvesting units with the ground slope of 0-33% were selected as study area located in Balikli Forest Enterprise Chief (Duzce-Golyaka). The study, the skid trails were sampled at 10 m intervals. Samples were taken again at 10 m intervals from the undisturbed area protected from skidding at least 25-30 m away from the skid trails. Soil compaction at the sample areas were taken was measured at 0-5 cm and 5-10 cm depths by using a hand penetrometer. Besides, soil loss and seedlings damage were measured on skid trails. Result of study, it was determined that soil compaction of 703 m2 per hectare in skid trails. Inasmuch as continuous skidding, soil erosion was determined different depths on samples from the skid trails, It was found that soil loss of 53.39 m3 (134009 ton) per hectare. Besides, there were not seedlings on a good part of skid trails, existing seedlings were lying, broken, and dismantled that were determined, it was found that residual damages on 6432 seedlings per hectare
