Abstrakt: Short-term changes of nematode assemblages were studied in field soil sown with regional and commercial grass mixtures and compared with those in a cultivated field in the course of one year. Total average abundance of nematodes in the grass mixture plots increased rapidly to 1308-2075 x 10 3 ind.m.-2 whereas in the field it remained relatively low (625 x 10 3 ind.m-2). The increase in population densities mainly concerned microbivores such as Panagrolaimus, Paraphelenchus, Aphelenchus and Aphelenchoides (950-1779 x 10 3 ind. m-2) followed by omnivores + predators (178-296 x 10 3 ind.m-2), while increase in plant parasite populations was slower (105-140 x 10 3 ind. m-2). The development of nematode assemblages suggests a great role of accumulation of above-ground as well as below-ground litter supporting microflora and microbial feeding fauna in initial stages of meadow restoration. In older stages, an increase of root density is expected simultaneously with multiplication of plant parasitic nematodes. Early successional development of soil nematode assemblages seemed to be faster in plots sown with regional grass mixture than in that sown with commercial grass mixture.
