In the Age of Modern Microbiology, Biofertilizers: A Rethinking of Crop Nutrition
In an era of rising ecological degradation, climate change, soil erosion, and biodiversity loss, global population expansion poses a danger to food security. In this perspective, utilising naturally occurring activities such as those supplied by soil and plant-associated microbes appears to be a potential option for reducing pesticide dependency.

Biofertilizers are organic agro-inputs that are "eco-friendly." Rhizobium, Azotobacter, Azospirilium, and blue green algae (BGA) have long been used as biofertilizers. Leguminous crops benefit from Rhizobium inoculant. Wheat, maize, mustard, cotton, potato, and other vegetable crops can all benefit from Azotobacter. Sorghum, millets, maize, sugarcane, and wheat are among the crops for which Azospirillum inoculations are advised.

Nostoc or Anabaena or Tolypothrix or Aulosira, blue green algae belonging to the cyanobacteria genus, fix atmospheric nitrogen and are utilised as inoculants for paddy crops produced in both upland and lowland settings. Anabaena, in conjunction with the water fern Azolla, contributes up to 60 kg of nitrogen per hectare every season while also enriching soils with organic matter.
