Variation in the soil at different ages of the red pi̇ne plantation area

This study has been done at Kastamonu Regional Directorate of Forestry, Sinop Forest Management Directorate, forest management units Gerze area. We determined to chancing the amount of carbon in the soil at pure red pine stands in the open area and different age groups under similar conditions. As a result of this study the value of the average amount of carbon at top soil layer (0-10cm); for a age class 62,18 t/ha, b age class 61,63 t/ha, c age class 71,42 t/ha and for control parcel 56,4 t/ha. When soil samples taken from top soil layers are evaluated in terms of carbon content, the average amount of carbon was found to be higher in the open area and the amount of organic matter was higher in the forest areas. The value of the average amount of carbon at lower soil layer (10-20cm); for a age class 64,55 t/ha, b age class 66,21 t/ha, c age class 72,67 t/ha and for control parcel 52,69 t/ha. When soil samples taken from top soil layers are evaluated in terms of carbon content, the average amount of carbon was found to be lower in the open area and the amount of organic matter was higher in the forest areas.
