ABSTRACT

The currently scientific researches try to develop highly efficient nitrogen fixation systems and the maximization of the nitrogen entries in the agro-eco-systems by the global increase of the biologically fixed nitrogen. For this purpose, in Arad agro-ecological area were carried out a range of researches regarding nitrogen biosynthesis of symbiotic processes and under the influence of nitrogen fertilizers.
