The abundance of some culturable soil microorganisms (bacteria and fungi) was examined at two Hungarian salt-affected soils of the Hortobagy region. In addition to the so-called “helper bacteria” ( Pseudomonas sp., nitrogen fixers), which are mainly attached to the rhizoplane, the abundance of other microbial groups (total number of bacteria, micromycetes, Actinomycetes ) were also assessed. A modified, selective plate dilution assay was used with increasing salt (NaCl) concentrations (5-50 g l -1 media), for assessing the salt tolerant ratio of specific microbial groups. The type of main salt-specific ions differed at the two sites, resulting more or less stressed pH conditions in the rhizosphere of the most typical halophytes. At Zám mainly the chloride, at Nyírőlapos, however mainly sulphate ions dominated in the samples (at an 80% level), which resulted in a more severe stress situation. Actinomycetes proved to be especially abundant in the salt affected soils examined. In almost all microbial groups, only the high in vitro concentration of salt (50 g l -1 ) reduced the abundance and the colony types of microorganisms. Nitrogen fixers, however were affected at lower salt concentrations and were found to be the most sensitive group at both sites. Variability of the existing colony types of micromycetes was reduced significantly by increasing levels of salinity. Soil- and rhizo-biological characteristics proved to be sensitive indicators of soil quality and environmental conditions.
