Alleviating plant salt stress and remediating saline soils are of great economic interest. Beneficial microbes such as Arbuscular Mycorrhizal (AM) fungi, Plant Growth Promoting Rhizobacteria (PGPRs), etc. are associated with many plants including trees. These beneficial microbes can cope up with salinity and help the plants to survive in such soils. In this study, diversity status of beneficial...

With the purpose of isolating and characterizing free nitrogen fixing bacteria (FNFB) of the genus Azotobacter, soil samples were collected randomly from different vegetable organic cultures with neutral pH in different zones of Boyacá-Colombia. Isolations were done in selective free nitrogen Ashby-Sucrose agar obtaining a recovery of 40%. Twenty four isolates were evaluated for colony and cell...
