THE LAST 15-YEAR PROSPECTS OF THE CREATION OF BIOSTIMULATORS BASED ON NITROGEN FIXING MICROORGANISMS

In order to create ecologically safe food products by improving the bioecological system based on microorganisms, it is important to breed nitrogen-fixing and phosphate-mobilizing bacteria on the basis of biotechnological methods and create biopreparations from strains for use in agriculture. As a result of the influence of various abiotic, biotic and anthropogenic factors of the environment on plants, the cultivation of useful plants in agriculture causes a number of problems every day. As a result of intensive demographic growth, the population's demand for food is increasing. The decrease in productivity due to the low production of plant products may lead to the problem of food shortage in the future. As a result of the use of large amounts of synthetic fertilizers to increase productivity, soil fertility has decreased and salinity has increased. Therefore, many studies are currently focused on improving plant-microorganism-soil system mediation relationships. Representatives of other classes of plants need nitrogen fixers. Treating them with biostimulators prepared on the basis of associative and free-living AFB living in the rhizosphere allows not to use synthetic fertilizers beyond the permissible limit in the future, thus improving soil fertility and growing environmentally friendly products.
