Determination of annual organic carbon sequestration in soil and forest floor of Scots pine forests on The 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 small 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 (P0.05) 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.
