Earthworm numbers and biomass (fresh mass) retrieved from mesocosms where winter wheat with seed dressings was sown or glyphosate-herbicide was applied.

Experimental factors		Adult earthworms (L. terrestris)		Juvenile unidentified, earthworms
Seed dressing	Herbicide	Number	Biomass (g)	Number	Biomass (g)
NO	No	1.6 ± 1.5	3.2 ± 3.6	38 ± 26	0.607 ± 0.411
	Yes	2.0 ± 1.2	5.4 ± 3.3	45 ± 21	1.008 ± 0.647
Insecticide	No	1.0 ± 1.4	3.0 ± 4.2	41 ± 18	0.840 ± 0.441
	Yes	2.0 ± 1.2	4.6 ± 3.8	38 ± 19	0.697 ± 0.399
Fungicide	No	2.2 ± 2.6	5.7 ± 7.2	45 ± 17	0.874 ± 0.329
	Yes	1.8 ± 2.2	4.9 ± 5.4	38 ± 26	0.918 ± 0.822

Means ± st. dev., n = 10 for factor seed dressing; n = 5 when glyphosate was applied. No significant effects of seed dressings or herbicide application on earthworm numbers or biomass were observed.
