"The aim is to unravel what entails biofertilisers their types nutritional qualities, their use and the methodology of producing them. In addition, the book takes care to incorporate critical perspectives which look into biofertiliser use as per its advantages the challenges surrounding its use of the future offered by it. Bio-fertilizers provide eco-friendly organic agro-input and are more cost-effective than chemical fertilizers. Bio-fertilizers such as Rhizobium, Azotobacter, Azospirillium and blue green algae (BGA) have been in use a long time. Rhizobium inoculant is used for leguminous crops. Azotobacter can be used with crops like wheat, maize, mustard, cotton, potato and other vegetable crops. Azospirillum inoculations are recommended mainly for sorghum, millets, maize, sugarcane and wheat. Blue green algae belonging to a general cyanobacteria genus, Nostoc or Anabaena or Tolypothrix or Aulosira, fix atmospheric nitrogen and are used as inoculations for paddy crop grown both under upland and low-land conditions. Anabaena in association with water fern Azolla contributes nitrogen up to 60 kg/ha/season and also enriches soils with organic matter. The book provides completeness of cover to the potentials of biofertilizers and expose them to current thinking on the subject, and will help them inculcate thoughts on the most profitable areas for future research."--Back cover
