Density and biomass of Collembola and Acarina were estimated in soil and in experimentally introduced substrates (litter bags with stems and leaves of Dactylis glomerata and mineral bags containing sand) in five meadows of different plant diversity ranging from almost monoculture (youngest meadows) to rich vegetation (several year old and permanent meadows). Studies were conducted in the Suwałki Lanscape Park (north-eastern Poland). The intensity of humification was positively correlated with biomass of microarthropods in soil, however the rate of liter disappearance rate was found not to be related to this parameter. The rate of humification process proceeded in the lowest rate in the youngest meadow. It was coupled with the slowest rate of litter colonization by microarthropods and the rapid by bacteria. In the soil of the youngest meadow the lowest and most variable density of microarthropods was recorded. The Shannon-Wiener diversity index for group Collembola was the higest in the youngest meadow despite low plant diversity.
