The most dominant nematodes in the field were bacterivorous genera (55 %). During succession the total abundance of nematodes in the abandoned field plots (AF; natural fallow), regional grass mixture plots (RGM), and commercial grass mixture plots (CGM) increased to 109, 140, and 154 x 104 ind.m-2. The dominance of bacterivorous nematodes decreased to 30 %, 30 %, and 35 %, respectively. The abundance and the dominance of root-fungal feeding nematodes increased in RGM (25 %) and CGM(24 %) treatments, that of plant-parasitic nematodes increased in AF (12 %). The abundance and the dominance of omnivorous nematodes increased mainly in AF (24 %), that of predacious nematodes increased in all treatments (6 %, 4 %, 3 %, respectively).
