 abstract={Protozoa (traditionally qualified as an element of animaFs kindgdom) and nematodes as smali organisms are defined as microfauna. They are abundant in soil environment and diverse both in terms of taxa and function. Protozoa are mainly bacteriovorous, some of them graze on fungi or algae, others are omnivores or predators. Nematodes also have different feeding habits. Among them there are plant-, bacterial-, fungal feeders and also omnivores and predators. Functional diversity of protozoa and nematodes results in complex interactions between microfauna, plants and microorganisms.Attack of high number of some plant-feeding nematodes on roots can seriously damage root system and result in a decrease of primary production - yearly losses caused by nematodes in grasslands were estimated at 6-10%. On the other hand, grazing of a smali amount of plant-feeding nematodes, below damage threshold, might stimulate the enlargement of root system and production of root exudates.Protozoa and nematodes enhance decomposition and nutrient-cycling; dead organie matter is decomposed by bacteria and fungi and some nutrients are released during this process, but majority of them is immobilized in microorganisms and could be released when bacteria and fungi are consumed by soil animals. Because of a high consumption and Iow assimilation ratę microbial grazers release considerable amounts of nutrients and the pool of nutrients available for the root inereases. Protozoa and nematodes account for 80-90% of the total N mineralisation contributed by soil fauna.},
