| Re: Biofertilizers tnau
The Tamil Nadu Agricultural University is teaches about the Biofertilizers. The Biofertilizers are defined as preparations containing living cells or latent cells of efficient strains of microorganisms that help crop plants uptake of nutrients by their interactions in the rhizosphere when applied through seed or soil. They accelerate certain microbial processes in the soil which augment the extent of availability of nutrients in a form easily assimilated by plants. Different types of biofertilizers: Rhizobium Azotobacter Azospirillum Cyanobacteria Azolla Phosphate solubilizing microorganisms(PSM) AM fungi Silicate solubilizing bacteria (SSB) Plant Growth Promoting Rhizobacteria (PGPR) Liquid Biofertilizers Get info about Biofertilizers in Tamil Nadu Agricultural University:   Groups of Biofertilizers by Tamil Nadu Agricultural University: N2 fixing Biofertilizers Free-living Azotobacter, Beijerinkia, Clostridium, Klebsiella, Anabaena, Nostoc, Symbiotic Rhizobium, Frankia, Anabaena azollae Associative Symbiotic Azospirillum P Solubilizing Biofertilizers Bacteria Bacillus megaterium var. phosphaticum, Bacillus subtilis Bacillus circulans, Pseudomonas striata Fungi Penicillium sp, Aspergillus awamori P Mobilizing Biofertilizers Arbuscular mycorrhiza Glomus sp.,Gigaspora sp.,Acaulospora sp., Scutellospora sp. & Sclerocystis sp.
