Net Fine Root Carbon Production in Pinus densiflora, Pinus koraiensis, Larix leptolepis and Quercus acutissima Stands, Gongju area, Chungnam Province, Korea

초록

This study was carried out to estimate annual carbon production by fine root in Pinus densiflora, Pinus koraicnsis, Larix leptolopis and Quercus acutissima stands of Gongju region, Korea Soil samples were taken at 0-30 cm. 30-60 cm, and 60-90 cm soil depths from April to November (monthly increment) method in 2007 using soil sampler. Fine root carbon biomass was higher at 0-30 cm soil depth than in the other soil depths Total fine root carbon biomass at 0-90 cm soil depth was highest in Larix leptolespis stand among the four study stands. Net fine root carbon production (kg ha(-1) yr(-1)) in Pinus densiflora, Pinus koraiensis, Larix leptolepis and Qucrcus acutissima stands were 889 kg, 2,266 kg, 851 kg, and 1,121 kg at 0-30 cm soil depth, respectively. Total net fine root carbon production (kg ha(-1) yr(-1)) was highest in Pinus koraiensis stand among the four study stands Fine root turnover rates in the four stands were ranged from 0.59 to 2 63 at 0-30 cm, 30-60 cm, and 60-90 cm soil depth.
