Summary
The results of daily counting of the colony forming units (CFU) number of bacteria capable of the ammonification (AMM) and
activity of the AMM process using ammonium concentrations after induction of the AMM by peptone in soil samples from fallow
and intensively cropped plots of gray forest soil are presented. Statistical analysis of visually observed wave-like dynamics of CFU
revealed statistically significant harmonics in CFU of these soils. The harmonics of the dynamic of CFU of different soils were fairly
close by their quantitative characteristics. This indicates not only the dynamic similarity, but also a comparable orderliness in the
functioning of the ammonifying component in the differently used soils. The daily dynamics of the ammonium concentration in
the soil samples was manifested in the form of curve accumulation of NH4+ in time. The presentation of the results of the dynamics
of NH4+ in the form of subtraction differences between the subsequent concentration of NH4+ and the previous one showed that
the dynamics of daily production of NH4+ just like the dynamics of CFU, has an oscillating nature. The observed differences in
the dynamics of NH4+ in the compared soil ecosystems (SE) - the fallow and intensively cropped plots are very minor. Thus, even
detailed monitoring the dynamic of AMM in SE do not allow to reveal significant differences in AMM of genetically identical but
differently used soils. Therefore, the process of ammonification cannot be used to identify differences in the “nitrogen” parameters
of the soil health.
