- 2. CONTENTS INTRODUCTION QUALITIES OF BIOFORMULATION AND CARRIERS SOLID CARRIER BASED FORMULATIONS LIQUID FORMULATIONS POLYMER ENTRAPPED FORMULATIONS REFERENCES
- 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
