Earthworm effects on carbon and nitrogen dynamics of surface litter in corn agroecosystems

We examined the influence of earthworms on surface litter decomposition in corn (Zea mays) agroecosystems in Wooster, Ohio. We employed a split-plot experimental design with 12 main plots, each 20 x 30 m and containing three 4.5 x 4.5 m field enclosures in which earthworm populations were (1) increa...
