The Effect of Earthworm (Lumbricus terrestris L.) Population Density and Soil Water Content Interactions on Nitrous Oxide Emissions from Agricultural Soils

Table 1

Mean earthworm mortality in the low, medium, and high earthworm densities according to 𝜃_g (%) treatment.

	Mortality Rate (%)
𝜃g (%)	Low^§	Medium	High
15	2.0 a^†	11.0 a	15.6 a
25	2.0 a	2.5 a	5.0 a
35	0.0 a	8.5 a	18.3 a
45	0.0 a	6.0 a	10.0 a

^†Within columns, means followed by the same letter are not significantly different according to Tukey-Kramer means adjustment (0.05).
^§Low, medium, and high refer to densities of earthworms per 0.033 m²: 10, 20, and 30, respectively.
