Determination of Soil, Litter Properties and Carbon Stock Capacities of Different Stand Types in Western Black Sea Region

Abstract

The aim of the study is to reveal how some of the physical and chemical properties of the soil and litters in the Pinus nigra, Pinus sylvestris and Pinus sylvestris-Pinus nigra stand mixture and how the amount of carbon stored varies according to the tree type. In this context, soil samples were collected from two different levels, litter examples were collected from two different layers including leaf and fermentation+humus and undisturbed soil samples were collected from three different depths. pH, electrical conductivity, organic matter, texture, bulk density, carbon rate and carbon content values were determined in soil and litter samples. According to the soil samples analysis results, the highest ph (7.74), electrical conductivity (147.85 μs/cm), organic matter (3.03%), carbon ratio (1.76%), carbon amount (6.72 t/ha), clay (24.81%) and silt (11.49%) values were determined in Pinus sylvestris-Pinus nigra stand mixtures. The highest sand value (73,60%) in Pinus sylvestris and bulk density value (1.42 gr/cm³) in Pinus nigra has been identified. The average values of pH (6.93) and carbon ratio (30.38%) in litter samples were determined in the highest Pinus sylvestris-Pinus nigra stand mixtures. According to the statistical analysis, it was determined that there was no statistically significant difference (p>0.05) in carbon amount, dust ratio and bulk density values in soil samples. In other analyzes, it was determined that there were significant differences between the groups (p<0.05). According to the results of the analysis of pH and carbon ratio in litter samples, there was no significant difference between the groups (p> 0.05).
