plants are the most sources for cadmium enters to human food and this element in food regime may be a serious threat to human health. thus, the effect of azotobacter inoculum (azotobacter chroococcum), mycorrhiza fungi (glomus intraradaices) , zinc sulphate and urea on cadmium convertation and growth parameters of fenugreek medicinal plant (trigonella foenum gracum l.) in cadmium polluted soils...

Alfred Koch has given considerable attention to the subject of nitrogen fixation by bacteria as resulting from their symbiosis with alga~. Many others have also investigated various features of this problem. In spite of all this there are numerous questions which remain unsolved. The use of soil cultures for such studies is objectionable on account of the soil's complexity, its variety of flora...
