Efficiency of application of biofertilizers on the basis of sewage sludge of treatment facilities of Odessa The article presents the results of the application of new biofertilizers in the technology of growing corn for grain. Biofertilizers – on the basis of sewage sludge of biological treatment plants «Southern» and «Northern» of Odesa with the addition of winter wheat straw and sunflower seed husk. The effectiveness of the application of biofertilizers based on sewage sludges was studied in a field experiment on black soil ordinary medium humus. According to the results of field research it is established that the use of new biofertilizers based on sewage sludge of biological treatment plants «Southern» and «Northern» of Odesa in corn cultivation technologies increases the quantitative characteristics of microorganisms of different ecological and trophic groups, which, in turn, helps to increase soil fertility and corn yield for grain. Keywords: biological treatment plants, bioorganic fertilizers, efficiency, ecological and trophic groups of microorganisms, rhizosphere, soil fertility.
