Effects of Vegetation Type and Management Practice on Soil Respiration of Grassland in Northern Japan

Table 1

Aboveground biomass (AGB), soil carbon (C) content, soil nitrogen (N) content, and bulk density in the Zoysia japonica (ZJ), control Miscanthus sinensis (MSc), and intentionally burned M. sinensis (MSb) plots.

Plot	AGB; (g d.w. m^−2)	C content (%); (𝑛=6)	N content (%); (𝑛=6)	Bulk density (g m^−3); (𝑛=3)
ZJ	330.5±12.3^1	13.16±1.13	0.81±0.10	0.38±0.03
MSc	N.D.	12.44±0.94	0.80±0.05	0.33±0.03
MSb	1218.1±137.1^2	12.94±0.62	0.86±0.05	0.38±0.03

All data indicated mean ± standard deviation. ¹Measured in April 2004 (𝑛=5), ²measured in April 2008 (𝑛=3). N.D.: no data. AGB data contained litter biomass. All soil samples were taken in May 2008, and there are not significant differences among the three plots (Scheffé’s test).
