3. INTRODUCTION
Biofertilizers - Biological Products Containing Living Micro
Organisms Which Promotes Plant Growth And Nutrients Supply
When Applied To Seeds, Plant Surfaces Or Soil.
Factors Determines The Success Rate Of Biofertilizers Are Microbial
Strains And Bioformulation .
Bioformulations - A Mixed Solution Containing Many
Bioinoculants(Microbial Strains), Sticking Agents And Nutrients
Which Can Promote Plant Growth.
Formulation Procedure May Differ Based On Many Factors Like
Inoculant Type, Soil Type, Available Resources, Type Of Application.
Detailed Understanding Is Very Important Since It Affects The
Abundance And Performance Of Bioinoculants.

4. VITAL QUALITIES
Bioformulation
Easy To Handle
Easy Delivery To Target
High Viability
Longer Shelf Life
Cost Effective
To Protect Bioinoculants
From Extreme
Conditions.
Carriers (Deliver Agents)
High Water Holding
Capacity
Cost Effective
Non Toxic
Easy To Handle
Easily Biodegradable
Should Support Wide
Vareity Of Bacteria

5. SOLIDCARRIERBASEDFORMULATIONS
Inoculants Are Mixed With Solid Carriers In Appropriate
Proportions. Carriers Are The Delivery Agents Which Are Inert
Materials Used For Microbes Transportation.
Types Of Solid Formulations Includes,
1. Soils - Peat, Coal
2. Plant Wastes - Composts, Farmyard Manure
3. Inert Materials - Polyacrylamide Gel, Alginate Beads
Drawbacks
High Contamination
Poor Quality
Shorter Shelflife
Expensive

6. Peat Formulation
Used As Carrier Of Choice For Decades
Popular Due To Successful Field Results
Pros
Successful Commercial Cultivation
High Water Holding Capacity
High Surface Area For Inoculants Growth
Cons
Prone To Contamination
Release Of Toxic Components (Sometimes)
Quality And Effectiveness Is Variable

7. LIQUID BIOFORMULATIONS
A Solution Contains Micro Organisms Along With Nutrients,
Cell Protectants And Additives Which Can Promote Plant
Growth And Survivability.
Aqueous Or Oil Based Products.
Pros - Protectants And Additives
Product Stability
Prevention From Osmolysis
Inoculants Protection From Extreme Conditions
Pros
Less Amount Of Inoculum Is Enough
Easy To Produce And Sterilize
Supports High Number Of Cells For Long Duration

8. POLYMERENTRAPPEDFORMULATIONS
A Formulation Contains Polymer Entrapped Inoculants
Along With Other Essential Components.
Production And Application Steps
Cells Mixed With Polymers After Mass Production
Chemical Solidification
Beads Formation With Live Cells Inside
Fermentation For Further Growth And Dried
Application Of Beads To Soil And Utilization Of Inoculants
Eg. Alginate Based Formulations.

9. Pros
Storage At Ambient Temperature For Long Duration
Easy To Produce And Handle
Non Toxic
Cons
Expensive
Requires More Times Of Handling
Slow Releasing Quality Of Inoculum
