This blog is very informative for Agriculture and botany students. It is about Horticulture Articles, Jobs, admission and organic farming.

TYPES OF BIOFERTILIZER

 Biofertilizers are Broadly Categorized into Four Groups

 1: Biofertilizers for nitrogen fixation (Bacteria-Symbiotic: - Rhizobium, Associative: - Azospirillum, Non-symbiotic: -Azotobacter, Acetobacter, Algae- Non-symbiotic: - BGA, Symbiotic: - Azolla). 

• Biofertilizers for phosphate solubilization or mobilization (Bacteria- Non- symbiotic: - Bacillus, Pseudomonas; Fungi - Non- symbiotic: - Aspergillus, Penicillium, Trichoderma; Symbiotic: - Arbuscular Mycorrhiza.

 • Biofertilizers for potassium solubilization or mobilization (Bacteria- Nonsymbiotic; - Frateuria).

 • Biofertilizers for decomposing organic matters (Cellulytic fungi- Trichoderma, Chaetomium aruanse, Aspergillus: Cellulytic Bacteria: Cellulomonas and Clostridium; Cellulytic Actinomycetes: - Nocardia and Streptomyces and Lignolytic fungi- Calvaria sp, Cephalosporium sp, and thunicola sp)
