This Presentation Deals With What Is A Biofertilizer, What Is A Bioformulation, Vital Qualities Of Bioformulation And Carrier Agents, Types Of Bioformulations ( Soild, Liquid And Polymer Entrapped Bioformulations), Pros And Cons And References Respectively.
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
