The influences of thinning (50% of standing density) and liming (Ca+Mg, 2 Mg ha−1) on soil chemical properties were investigated for 2 years (2001, 2002) in 40-year-old pitch pine (Pinus rigida Mill.) and 44-year-old Japanese larch (Larix leptolepis Gord.) plantations established on similar soils. In general, soil properties varied significantly among(More)
We investigated the influence of stand density [938 tree ha−1 for high stand density (HD), 600 tree ha−1 for medium stand density (MD), and 375 tree ha−1 for low stand density (LD)] on soil CO2 efflux (R S) in a 70-year-old natural Pinus densiflora S. et Z. forest in central Korea. Concurrent with R S measurements, we measured litterfall, total belowground(More)
We determined a suitable amount of fertilizer for konara oak (Quercus serrata) and Japanese zelkova (Zelkova serrata) planted in a harvested pitch pine (Pinus rigida) plantation. Two-year-old bare-root seedlings of konara oak and one-year-old containerized seedlings of Japanese zelkova were planted in April 2011. Three plots were established for each tree(More)
