Abstract

Determination of annual organic carbon sequestration in soil and forest floor in Scots pine forests in Turkmen Mountain (Eskisehir, Kutahya) Abstract: This study was aimed to determine the annual organic carbon stocks in forest floor and soil in Scots pine (Pinus sylvestris L. subsp. hamata (Steven) Fomin.) forests. Research was conducted with two samplings in 2003 and 2013 on massive of Turkmen Mountains (Eskisehir, Kutahya) where located in West Central Anatolia Region in Turkey. Samplings were performed in 40 plots at pole (dbh=11.0-19.9 cm) and young tree (dbh=20.0-35.9 cm) development stages on different aspects, elevation, slope degree and slope positions. Data were evaluated with paired-samples t test. Soil organic carbon stocks show a significant (P 0.05) difference between 2003 and 2013. Depending on these differences, accumulated carbon stocks were 2.88 Mg C ha-1 yr-1 in soil and 0.02 Mg C ha-1 yr-1 in forest floor. Keywords: Scots pine, soil, forest floor, carbon sequestration Turkmen Dagi (Eskisehir, Kutahya) saricam ormanlarinda toprak ve olu ortude biriken yillik organik karbon miktarinin belirlenmesi Ozet: Bu calisma, saricam (Pinus sylvestris L. subsp. hamata (Steven) Fomin.) ormanlarinda toprak ve olu ortude biriken yillik organik karbon miktarinin belirlenmesi amaciyla yapilmistir. Arastirma, Bati Ic Anadolu Bolgesi’nde yer alan Turkmen Dagi’nda (Eskisehir, Kutahya) yurutulmustur. Orneklemeler, direklik (d1,3=11,0-19,9 cm) ve ince agaclik caginda (d1,3=20,0-35,9 cm) bulunan, farkli baki, yukselti, egim ve yamac konumu ozelliklerine sahip 40 ornek alanda gerceklestirilmistir. Veriler bagimli iki orneklem t testi ile degerlendirilmistir. Topraktaki organik karbon miktari 2003 ve 2013 yillari arasinda onemli bir farklilik gosterirken (P 0,05). Arastirma sonuclarina gore toprakta 2,88 Mg C ha-1 yil-1, olu ortude 0,02 Mg C ha-1 yil-1 karbonun depolandigi belirlenmistir.
