Benefits and Limitations of Rhizobium-Legume Symbiosis and Nitrogen Fixation Under Libyan Saline Soil: Mini Review

Biological Nitrogen Fixation (BNF) donates to productivity both straight by increasing the production of legume and indirectly by improving soil fertility. BNF is the cheapest and environment friendly procedure in which nitrogen fixing bacteria (Rhizobia), interacting with leguminous plants. Rhizobium is the most well-known species of rhizobial group that acts as the primary symbiotic fixer of nitrogen, increased farming of legumes is important for the renewal of nutrient-deficient soils and providing required nutrients which importance s as food for human beings and animals. Some environmental factors such as salinity, which is become one of the severe difficulties in worldwide farming production. Where, soil salinity limits the productions of both feed and grain legumes.
