“…C, Ca, K and Mg had the highest concentration in the branches and other parts. Similar to the findings of our study, Shin et al (2011) found that K, Ca and Mg had the highest concentration in the leaves of the oak trees while Ca and K had the highest concentration in the branches and barks. Mun et al (2007) found the highest density in K, Ca and Mg in the leaves, and in K, Ca and Mg in the branches and barks.…”

The carbon cycle came into the spotlight due to the climate change and forests are well-known for their capacity to store carbon amongst other terrestrial ecosystems. The annual organic carbon of litter production, forest floor litter layer, soil, aboveground and belowground part of plant, standing biomass, net primary production, uptake of organic carbon, soil respiration, etc. were measured in Mt. Worak in order to understand the production and carbon budget of Quercus serrata forest that are widely spread in the central and southern part of the Korean Peninsula. The total amount of organic carbon of Q. serrata forest during the study period (2010-2013) was 130.745 ton C ha . As a result, the net ecosystem production of Q. serrata forest estimated from carbon fixation and soil respiration was 0.963 ton C ha -1 yr -1. Therefore, it seems that Q. serrata forest can act as a sink that absorbs carbon from the atmosphere. The carbon uptake of Q. serrata forest was highest in stem of the plant and the research site had young forest which had many trees with small diameter at breast height (DBH). Consequentially, it seems that active matter production and vigorous carbon dioxide assimilation occurred in Q. serrata forest and these results have proven to be effective for Q. serrata forest to play a role as carbon storage and NEP.

“…The annual input of branch litter accounts for a substantial percentage of the total annual litter production and plays an important role in the dynamics of temperate forests (Harmon et al 1986). Litter production from branches accounts for approximately 12-22 % of total litterfall in temperate Quercus forests (Bray and Gosz et al 1972;Mun 2004;Shin et al 2011). Nevertheless, only a few studies have examined decomposition in relation to branch age rather than branch thickness (Upadhyay and Singh 1985;Mun 2004;Li et al 2009).…”

Litter decomposition is a critical process for the maintenance of terrestrial ecosystems. Although large quantities of organic matter and nutrients are supplied by branch litter, its decomposition has received little attention. In this study, we focused on Quercus mongolica, one of the most common temperate deciduous woody species in the Northern Hemisphere, to investigate the age-related decomposition rate of branches. Branches of different age classes (2, 4, 7, 10, and 13 years), downed after a summer windstorm, were collected, and mass loss was measured over 24 months using the litterbag method. Litterbag samples were retrieved every 4 months and analyzed for dry weight, carbon (C), nitrogen (N), lignin, and cellulose concentration, and also two litter quality indices (C/N and lignin/N) were calculated. Mass loss by decomposition was significantly faster in 2-year-old branches (34.78 %) than in 13-year-old branches (25.71 %). Branch decomposition showed a negative relationship with the initial C concentration, C/N, and lignin/N, but a positive relationship with the initial lignin and N concentrations. The decomposition rate differed significantly between different branch age classes and initial litter qualities and was strongly influenced by the initial N concentration and C/N. Overall, the results showed that total N and C/N might be the key factors in the decomposition of Q. mongolica woody materials, and they could be used as predictive indices of branch decomposition in future studies.
