Results of ANOVAs for effects of soil treatment (homogeneous vs. heterogeneous small vs. heterogeneous large scale), earthworm (with vs. without) and their interactions on total, aboveground and belowground mass of Leymus chinensis at the whole pot level.

Effect	DF	Total mass	Aboveground mass	Belowground mass
Soil treatment (S)	2, 30	2.7#	0.6ns	3.5 *
Earthworm (E)	1, 30	13.8 ***	23.4 ***	0.3
