Abstract
This study was carried out to estimate net fine root carbon production in Quercus variabilis natural stands in Chungiu area. Soil samples were taken in 0-30cm, 30-60cm, and 60-90cm soil depths from April to November using soil sampler. Fine root carbon biomass was higher in 0-30cm soil depth than the other soil depths. Net fine root carbon production (kg/㏊/yr) were 671kg in 0-30cm soil depth, 599kg in 30-60cm soil depth, and 479kg in 60-90cm soil depth, and 1749kg in 0-90cm soil depth. fine root turnover rates were 0.43 in 0-30cm soil depth, 0.96 in 30-60cmsoil depth, and 1.03 in 60-90cm soil depth. N, p, K, and Mg input into the soil (kg/㏊/yr) due to fine root turnover at 0-90cm soil depth in this study were 33.9kg, 1.8kg, 11.4kg and 20.1kg, respectively.
