Coarse root biomass properties in scotch pine stands of Alucra, Giresun

In this study, Giresun Province region Alucra some soil properties of pure and blended Scotch stands were trying to determine. In the study by a variety of features, some soil properties stand and position were also measured. For this purpose, Giresun Forest District Office, Espiye Forest Administration Directorate, within the boundaries of Seed and Conducting with Esen 2 (20-40 years) age class 9; 3 (40-60 years) age class 11; 4 (60-80 years) age class 9 and 5 (80-100 years) age class to 16 randomly selected experimental area is a total of 45 units. In this experiment, several selected areas and some soil properties change stand properties were investigated.Some of the purposes of determining soil properties in the soil pit 80x180 cm in size from four depth levels (0-20 cm, 20-40 cm, 40-60 cm and 60-100 cm) soil samples were taken. Soil samples taken in the soil texture, soil organic matter, soil reaction, soil salinity analysis are carried out. For determination of the trial fields stand feature of all trees were measured and age was determined stand site index. In addition, each instance relating to the field elevation, slope, cared for and coordinates field trials have been identified.As a result of analysis of data obtained was evaluated with the highest rate of sand ür Çs + L was found. In the second type, and the most recent Çs Çs + G type was out. Clay ratio increased, decreased levels deep. pH values increased as soil depth increased levels. If the pH value of the load Çs type was found. Yet the amount of organic matter soil depth increased, decreased levels were observed. The highest amount of organic matter in the upper soil Çs + G, and at least as Çs Çs + L-type was found. In general, the soil still inversely proportional to the depth of the salinity levels were decreased. According to the sandy soil above cared for have been found to be higher in shaded cared. In shaded cared pH value lower than the overall look is sunny came cared. The amount of soil organic matter in the shaded cared was higher compared to sunny cared. In 0-20 cm soil depth examination shaded salinity levels (30.17%), from sunny cared (% 29.11) was more out.Key Words: Soil Properties, stand age, site index, Pinus sylverstris , Giresun
