Abstract: | The effects of fertilization control (C), 200kgNha–1+25kgP ha–1 (LNP) and 400kgNha–1+ 50kgP ha–1 (HNP)] on fine root dynamics were examined in a 40-year-old Larix leptolepis plantation in central Korea. The average fine root biomass during the growing season for C, LNP and HNP was 957, 934 and 814kgha–1, respectively, whereas the fine root production for C, LNP and HNP was 2103, 2131 and 2066kgha–1, respectively. Nitrogen and P inputs into the soil via fine root turnover for C, LNP and HNP were 23.0 and 1.2, 23.3 and 1.2 and 22.6 and 1.2kgha–1, respectively. There were no significant differences in fine root biomass, production and N and P inputs through fine root turnover between the fertilization treatments during the first growing season after fertilization. |
