Abstract

This review article analyzes the measures used to restore the fertility of saline soils and the mechanisms of biological nitrogen fixation and soil properties improvement by alfalfa through legume-rhizobium symbiosis. Based on scientific sources, the mechanisms of improving the properties of saline soils, salt tolerance of legumes, rhizobacteria reducing soil salts and stimulating plant growth were studied. Studies show that alfalfa improves the amelioration of soils, reduces salinity, and reduces the level of groundwater in the surface layer. This property of alfalfa is associated with a strongly developed root system. Alfalfa accumulates 300-400 kg of nitrogen per 1 ha of area for 3 years.
