Earthworm populations in soils disturbed by trampling

Auteur :
PIEARCE, T. G.

Description :
Heavy trampling by livestock in pasture entrances considerably reduced earthworm density and biomass. All species showed a downward shift in vertical distribution. A laboratory experiment demonstrated the great effectiveness of A. Conga in ameliorating the effects of soil compaction. Earthworm population changes on trampling are likely to facilitate recovery of soil drainage once trampling ceases. (l'A.).
