ألمانية. The object of the present study was to determine the effect of conventional-tillage (plough) or conservation-tillage (mulch seed) and additional of green fallow or winter wheat as previous crops on the biological activity in the soil assessed by the bait lamina test after von Törne. Also the abundance of springtails and predatory mites was studied in the same plots. Winter wheat was the standing crop on all plots. During 3 months (April to June 1997) 8 soil cores to a depths of 15 cm each were taken monthly from each plot to define the abundance of the two mesofauna groups springtails and predatory mites. In addition 3 groups of 16 bait laminae were exposed for 8 days each month in the 4 studied plots. The biological activity of the soil increased successively from plough/winter wheat to plough/green fallow to conservation-tillage/winter wheat to conservation-tillage/green fallow. Abundance of springtails and predatory mites is in plots under conservation-tillage (mulch seed) higher than in plots under conventional-tillage (plough). The effect of the plough seems to be more negative than that of one year green fallow positive.
