Vedclass · Answer

(C) The fertility of the soil in rice fields is significantly improved by the use of biofertilizers like $Blue-green$ $algae$ (cyanobacteria).Specifically,species such as $Aulosira$ $fertilissima$ are known to be excellent nitrogen fixers in waterlogged rice fields.These organisms fix atmospheric nitrogen into ammonia,which increases the nitrogen content of the soil and promotes plant growth.$Rhizobium$ is typically associated with leguminous plants,not rice.
