In a four-year field trial comparing four different maize cropping systems (conventional cropping, intercropping, maize with rye cover crop, and maize meadow) the earthworm and collembola populations as well as several activities of soil microorganisms were determined. Vegetation between the maize rows was beneficial to animals and soil microorganisms. This cover not only provided nutrients but created also a favourable microclimate. In maize meadow, which was never tilled except in the seed band, earthworm and collembola populations were highest. The large vegetation mass and root production of the rye system particularly stimulated the soil microorganisms
