Investigations of site properties with some wood characteristics in black alder stands that formed in different spacings

In this research, black alder wood in Trabzon (Maçka) and Giresun (Erimez) was researched. Especially the black alder wood's grown in different habitat conditions effects of spacingin the same of anatomical, physical and mechanical properties and features of region and the black alder wood was researched. Firstly, 10 sample plots were taken from the spacing region where our researc will be held and 1m timber was taken and numbered from trees between 2 and 4 metres from distance of 1m*1m, 2m*2m, 3m*3m, 4m*4m and 5m*5m within same anatomical, mechanical and physical analysis for each sample area and then these sample plots were given to workshop for cutting. Mechanical analysis (sand, silt and clay rates) has been made by tested soil sampşes (0-30 cm, 30-60 cm, 60-90 cm) and along with this soil acidity (ph), soil organics matter (SOM), amounts of usable water capacity (UWC) are determined. Conjunction with examined wood samples, specific gravity, humidity, pressure resistance which parallel to the fiber, the flexion and, modulus of flexion resistance elasticity are determined, the grown in different climate conditionsof black alder woods physical and mechanical properties based on to investigated gap effects with statistical analysis. As a result of this study, to cater demands of wood raw material in our country, to grow better alder tree which is rapid growth species, gap distance and breeding zone investigated and the data were obtained to prepare a substructure to Forest Enterprises Chief.
