[The intensification of biological nitrogen fixation by using ammonium carbonate compounds and the routes of their action on microorganisms and plants].

The intensification of activity of associative and symbiotic nitrogen fixation while using low amounts of ammonium-carbonate compounds, carbonic-ammonium salts, in particular, has been established. The main ways and mechanisms of the action of ammonium-carbonate salts as a new and perspective agrochemical on physiological and biochemical processes of microorganisms and agricultural plants were presented on the basis of the analysis of literary information and the author's investigations.
