摘要：

Effect of anaerobically digested pig slurry on the structure of free-living and plant parasitic nematode communities of natural grass stands and sown grass monoculture was examined in experimental conditions. The application of slurry influenced the proportion of trophic groups of nematodes. Reduction of plant parasitic nematodes was found on manured plots of both types of grass stands. regardless of slurry doses. At natural grass stands the proportion of plant feeders reached 32.6-45.8% (vs 60.3% at control) at sown grass monoculture it was 48.9-55.6% vs 62.7%. The proportion of bacterial feeders increased after manuring. Stimulating effects on the nematodes of omnivores and predators were also found. Ecological parameters based on trophic and community levels showed positive effects of anaerobically digested pig slurry on the soil environment.
