DESCRIPTION |
|
| Biofertilizers or microbial inoculants include biologically active and efficient bacteria, actinomycetes, Azolla, mycorrhizae etc. that can provide plant nutrients viz. nitrogen and phosphorus at cheaper cost when compared with chemical fertilizers. Moreover, biofertilizers and organic manures are environment friendly and important basic inputs for sustainable agriculture. Their integrated uses thus can cause a reduction in application of chemical fertilizers and pesticides and overall cost of cultivation of crops. The monograph deals with various aspects of biofertilizers and manures, and technologies for their production and use. The biofertilizers viz. Rhizobium, Azotobacter, Azospirillum, blue-green algae, Frankia, Mycorrhizae, Rhizobium sp. and mineral phosphate solubilising microorganisms viz. Pseudomonas, Bacillus, Apergillus, Penicillium and others have been discussed in different chapters. The methods for production of enriched manures, factors affecting composting, role of cellulytic and lignolytic micro-organisms, methods of vermicomposting and standards for maturity of compost have been discussed in detail. The book is useful for the farmers and NGOs, interested in organic farming and will serve the purpose of both biologists and farm scientists, who are interested in using renewable and alternative sources of energy as organic farming inputs. |
