Biological activity of soil bacteria that stimulate plant growth: nnitrogen fixation, phosphate solubilization, synthesis of siderophores. prospects for the development of microbial consortiums

The review provides literature data on soil bacteria that fix atmospheric nitrogen, solubilize phosphates and synthesize siderophores, thereby stimulating plant growth.The prospects of creating bacterial consortia for application to the soil in order to increase crop productivity and reduce the doses of fertilizers are considered.The use of rhizospheric bacteria capable of fixing atmospheric nitrogen, mineralizing inorganic and organic phosphates, increasing the bioavailability of insoluble iron, as well as their consortia, meets the objectives of sustainable agriculture, increases soil fertility and increases crop yields.The combined use of bacteria that stimulate plant growth with mineral fertilizers makes it possible to reduce the amount of fertilizers applied, which is an undoubted trend in sustainable agriculture.Research on the possibility of using various preparations of soil bacteria that stimulate plant growth has been widely carried out abroad in recent years, these studies are relevant forRussian agriculture, have prospects for import substitution and are necessary to achieve technological sovereignty in this area.
