Biofertilizer Production TNAU

Sir my father is a farmer and I want to set up a new Bio-fertilizer Plant in my village for Villagers. Would you please tell from where can I get more information on setting up of Bio-fertilizer Production Plant? Is it available on Tamil Nadu Agricultural University (TNAU) Agritech Portal? If yes, provide me.

Re: Biofertilizer Production TNAU

Organic farming system in India is a method of farming system which primarily meant at cultivating the land and raising crops in such a way, as to keep the soil booming and in good healthiness by use of organic wastes (crop, animal and farm wastes, aquatic wastes) and other biological materials along with useful microbes (biofertilizers) to release nutrients to crops for increased sustainable production in an eco-friendly pollution free environment.

Biofertilizer

Biofertilizers are well-defined as preparations containing living cells or latent cells of efficient strains of microorganisms that aid crop plants acceptance of nutrients by their interactions in the rhizosphere when applied through seed or soil.

They accelerate certain microbial processes in the soil which expand the extent of availability of nutrients in a form easily assimilated by plants.

Very frequently microorganisms are not as efficient in natural surroundings as one would expect them to be and therefore artificially multiplied cultures of efficient selected microorganisms play a vital role in hastening the microbial processes in soil.

Use of biofertilizers is one of the important components of combined nutrient management, as they are cost effective and renewable source of plant nutrients to supplement the chemical fertilizers for sustainable agriculture.

Several microorganisms and their association with crop plants are exploited in the production of biofertilizers. They can be grouped in different ways based on their nature and function.

S. No. Groups Examples

N2 Fixing Biofertilizers
1. Free-living Azotobacter, Beijerinkia, Clostridium, Klebsiella,
Anabaena, Nostoc,
2. Symbiotic Rhizobium, Frankia, Anabaena azollae
3. Associative Symbiotic Azospirillum

P Solubilizing Biofertilizers
1. Bacteria Bacillus megaterium var. phosphaticum, Bacillus
subtilis Bacillus circulans, Pseudomonas striata
2. Fungi Penicillium sp, Aspergillus awamori

2. Ectomycorrhiza Laccaria sp., Pisolithus sp., Boletus sp., Amanita sp.
3. Ericoid Mycorrhizae Pezizella ericae
4. Orchid Mycorrhiza Rhizoctonia solani

Biofertilizers for Micro nutrients
1. Silicate and Zinc Solubilizers Bacillus sp.

Plant Growth Promoting Rhizobacteria
1. Pseudomonas Pseudomonas fluorescens
