What is Biofertilizer ? A biological active products of bacteria,algai,fungi which gives plant nutrients by fixation /solubilization.
Why Biofertilizers need?
Types of biofertilizers(Organic) N2 Fixing Phospate solubilizing Biofertilizers for Micro nutrients(new) PGPR Phosphate mobilizing Free living Azotobacter, Anabaena, Blue green algae. Bacteria Bacillus subtilles Fungi Pencillium sp Symboitic Rhizobium Anabaena azollae Associative Symboitic Azospirillum Silicate and Zinc solubilizers Bacillus Pseudomonas Pseudomonas fluorescence Mycorrihiza Glomus sp Amanita sp Boletus sp
Nitrogen fixing Biofertilizers Rhizobium :  Most popular biofertilizer  Contain symbiotic bacterium  Mixed with charcoal powder  Present in root nodes of legumes plants  Fixes 20-40 kg of N/acre/sesion  Brings 15-30% improvement in year Effectivness Dependance: 1. Soil type 2. Climate conditions etc.. Ex:(Red,Black,Green)Bengal gram(pulses)Soa bean(Oil seeds,) etc…..
Azotobacter :  A free living Nitrogen fixing aerobic bacterium(Activity)  Fixes the atmospheric nitrogen by converting into ammonia  Fixes atm Nitrogen in Rhizosphere  Requires Carbon & calicum to fixes in soil  Main Used for non-legumes  Brings 20% improvement inPaddy,Wheat,Sugarcrane,Potato,etc…  Produce some antibiotic subustances  Synthesis plant growth subustance (Vitamin B, gibberellins.etc..)
Azospirillum :  A free living fixing Nitrogen microorganism  Activity: Asymboitic Nitrogen Fixitation  Contain associative symbiotic bacterium  Gives good results mainly in maize,Sugarcrane,wheat,vegatables,rice etc…  Nitrogen fixing ability is 20-40 kg/ha  Similar to Azobacter
Azolla :  A free-floating water fern used as Biofertilizer for wetland rice  Activity:Symboitic Nitrogen Fixation  It’s N-fixing ability is becauseofAnabaena as Edosymbiont 5.5 to7 pH soil is good for this.  2500 to 3000 Kg Azolla issufficient for one ha. Field .  Azolla fixes 30-40 Kg nitrogen / ha. / year. Rich in proteins and contain almost all the essential aminoacids.  Along with Anabaena it used as green manure.
Phospate solubilizing Biofertilizers  Phosphorus is very important nutrient of plants as it required in large quantity .  Phosphorus get fixed & becomes unaviable to plant at very high/low PH level  Release 12kg /P/acre/season  Generally non symbiotic Requid Quantity to methods recommandered for applications  200 gms enough for sead treatement of groundnet,wheat.  100gms for small seed treatment  For root dipping method 1kg of PSB taken in 10-15 litres  It Effective for Paddy,Oil seeds, vegatables
Phosphate Mobilizing Biofertilizers A Symbiotic biofertilizer  Mutual association between a fungus and the roots of a vascular plant.  The fungus colonizes the host plant's roots, either intracellularly or extracellularly  This association provides the fungus with access to carbohydrates In return, the plant gains the benefits of the mycelium's higher absorptive capacity for water and mineral Ex: Coffee etc… Mycorrhizal and non mycorrhizal barley plants after colonization with (Kogel, Giessen)
Plant Growth Promoting Rizobacteria (PGPR)1. Indirect PGPR :  Activity : Bio pesticides  It used in Antibiotic ,Hydrolytic enzymes, Exopolysaccharides etc.. 2. Direct PGPR :  Activity : Bio fertilizers  Used in Nitrogen fixation , phosphate&potassium solubilization  It Produces IAA , cytokinins , Gibberelins, Ethylene .
Blue green Algae :  A simplest , living autotropic plants  Distributed in aquatic environment  Found in climatic conditions of snow and in hot spring  Ability to photosynthesis food  B.G.A. fix approximately 25 Kg N/ha/year. - B.G.A. is suitable nitrogen fixer for paddy field . - Main sp Anabaena and Nostoc 
Conclusion Relatively more effective than chemical fertilizers. Significant effect in Biomass production and grain Productivity. Biofertilizer have great role in increasing the crop production. They improve the soil health status. Cost is lower than other fertilizers.
