Modern condition of biological nitrogen-fixing problem and future trends of diazotrophe practical application in biotechnology and plant-growing are reviewed. Main requirements to nitrogen-fixing bacteria, which serve as basis for the existing microbiological preparations are analyzed as well as their general production scheme. Particular attention is payed to the researches which are aimed at engineering of association based on cyanobacteria and nodule bacteria; practical application of bacterial and artificial polysaccharides, producing of biological preparations with plant lectins. Different preparatory forms of nitrogen-fixing microorganisms effectively increase the productivity of plants and can be recommended for agricultural production. The use of bacterial preparations leads to a slight increase in the cost of production while the economic effect of using nitrogen-fixing bacteria is achieved due to the additional crop yield, the savings made on fertilizers and the reduction of other production costs. The evaluation of economic effect of the preparation practical application which were modified with homologous lectin is given.

Key words: biological nitrogen, symbiotic and associative nitrogen-fixing bacteria, microbiological preparations, plant productivity.
