Earthworms interactively affected the influence of seed dressings on collembola activity, whereas collembola increased earthworm surface activity but reduced soil basal respiration.
2
Results: Seed dressings (particularly fungicides) increased collembola surface activity, increased the number of protozoa and reduced plant decomposition rate but did not affect earthworm activity.
3
Earthworms and Collembola increased biomass of seeds, shoots and roots of wheat.
4
Earthworms, Collembola and litter distribution affected plant growth, N acquisition and aphid development in an interactive way.
5
Signatures of delta(13)C proved density responses of Collembola taxa to be related to the added mulch materials.
6
Increased plant growth by earthworms and Collembola was mainly due to increased transfer of N from soil (rather than litter) into plants.
