Examples of microorganism for fertility management

A) Fungi

Chaetomium                Trichoderma                            Trichothecium              Poria

Mucor                          Verticillium                              Zygorynchus                Humicola

Rhizoctonia                  Rhizopus                                                                      Penicillium (Blue mould)

Cladosporium              Fusarium                                 Alternaria                    Botrytis

Polyporus

B) Bacteria

Bacillus spp.

Clostridium spp.

Pseudomonas spp.

Xanthomonas spp.

Vibrio spp.

Micrococcus spp.

Cytophage  etc.

C) Actinomycetes: Nocardia

D) Nitrogen fixation

Fixing of atmospheric nitrogen in soil. Reclamation of soil- unfertile soil is converted into fertile one.

i) Asymbiotic microbes-helping in Asymbiotic Nitrogen Fixation

Bacteria

Azotobacter                             Clostridium

Rhodospirillium                       Chlorobium

Diplococcus                            Thiobacillus

Mycobacterium                       BGA- Cylindrospermum

Calothrix                                 Gleocapsa

Nostoc                                     Anabaena

Oscillatoria                              Anabaenopsis

Fischcherella                           Scytonema

Stigonema

Fungi:  Pellularia                     Yeast

            Cladosporium              Mactosporium

            Rhodotorulla

2) Symbiotic Nitrogen fixers e.g. Rhizobium spp. , R. Leguminosorum

E) Phosphate Solubilization

Certain bacteria & fungi e.g. Mycobacterium, Flavobacterium, Micrococcus Penicillium, Sclerosium, Aspergillus & Fusarium participate in the conversion of insoluble inorganic phosphate into soluble inorganic phosphate in the soil & thus increase soil fertility
