It is generally assumed that younger soil inhabits more opportunistic (r-selected) communities. In our research we compared opportunism of soil bacterial communities from six fallow fields, six meadow fields and four transitory from fallow to meadow fields. We hypothesized that fallows, which are few years old, should contain more r- selected bacterial communities than soils from meadows, which were consistently managed for many years. Culturability was calculated from the ratio of Colony Forming Curves from agar plates to the total number of cells from epifluorescence microscopy. To compare the rate of growing activity, new colonies were counted on plates every day for seven days. There were no differences in culturability ratio of soil bacterial communities between ecosystems.
