EFFECTS OF LOGGING TECHNIQUES ON PHSICAL PROPERTIES OF FOREST SOILS IN ORIENTAL SPRUCE STANDS

Öz

In this study, we investigated the effects of three timber logging techniques (skyline, tractor and manpower) on some physical properties of Oriental spruce (Picea orientalis) forest soil. Permeability, moisture, water holding capacity, bulk density, fine and coarse soil and soil texture (sand, silt and clay) at two soil depths (0-15 cm and 15-30 cm) were determined at the loading, unloading, skid road, under skyline and undisturbed plots. The results show that in the region machine passes and manpower can have an important influence on soil permeability, bulk density and the soil water balance, and may therefore considerably affect soil organisms, root development, nutrient and water uptake and in turn lead to reduced Oriental spruce tree growth. Keywords: Logging, Oriental spruce, Soil damage

DOĞU LADİNİ MEŞCERELERİNDE BÖLMEDEN ÇIKARMA ÇALIŞMALARININ ORMAN TOPRAĞININ FİZİKSEL ÖZELLİKLERİ ÜZERİNE ETKİLERİ

Öz

Bu çalışmada üç farklı bölmeden çıkarma tekniğinin (insan gücü, traktör ve hava hattı) Doğu ladini orman topraklarının bazı fiziksel özellikleri üzerinde etkileri araştırılmıştır. Tomrukların yüklendiği, sürütüldüğü, boşaltıldığı, hava hattı altı ve bozulmamış doğal alan, topraklarının permeabilite, nem, su tutma kapasitesi, hacim ağırlığı, ince ve kaba kısmı ve tekstürü iki derinlik kademesinde (0-15 cm ve 15-30 cm) belirlenmiştir. Sonuç olarak, Artvin yöresinde traktör ve insan gücü ile yapılan bölmeden çıkarma çalışmalarının orman topraklarının permeabilite, hacim ağırlığı ve toprak suyu dengesinde önemli bir etkiye sahip olduğu, bu etkilenmenin de toprak organizmaları, bitkilerin kök gelişimi, bitki besin elementleri ve bitkilerin su alımı açısından olumsuz etkiler doğuracağı ve zamanla Doğu ladini ağaçlarının gelişimini yavaşlatabileceği sonucuna varılmıştır.
