[Thermodynamic interpretation of the nitrogen status of forest gray soil agrocenoses]

Thermodynamic approaches used in soil agrochemical studies allow to determine the direction of processes occurring in soils and to provide theoretically meaningful predictions of changes in ecosystems as a whole in response to various factors. Analysis of redox reactions of the NH4+ reversible NO3- equilibrium in agrocenoses of gray forest soil has shown that the additional introduction of nitrogen fertilizers is undesirable both from the economical and ecological points of view, since the dominating process occurring with the loss of nitrogen from the soil in the form of gaseous compounds is thermodynamically most preferred.
