Carbon dioxide absorption for Liriodendron tulipifera using fertilization

We conducted this study to obtain the basic information for forest biomass estimation in a national unit by predicting the carbon dioxide absorption of the early growth of Liriodendron tulipifera based on several fertilization methods. The study site, located in Gimje-si, Jeollabuk-do, consisted of 11 fertilizer treatment plots, repeated three times by species. Five sample trees were planted in each plot, and a total of 165 sample trees of each species were planted. Of these sample trees, every two samples of the L. tulipifera were cut down in order to estimate the biomass. The results were similar to the analysis results for the mean volume. In comparison to the control group with a biomass of 310.35 g, the biomass of the LLF and HLF groups was relatively high, whereas the biomass of the CF and CP groups was relatively low. As a result, the LLF-150 group had the highest biomass at 96.36 g, and all of the treatment groups had higher biomasses than the control group (16.14 g) in the case of branches. In the case of leaves, the HLF-150 group had the highest biomass at 239.48 g and the CP group had the lowest biomass at 115.60 g. In the case of roots, the LLF-150 group had the highest biomass at 495.45 g, and only the CP group (186.82 g) had a lower biomass than the control group (194.90 g).
