Role of microbial inoculants in liquid fertilizers for next generation farming

Background Microbial inoculants are an important part of the integrated nutrient supply systems as they are a cost-effective and renewable source of plant nutrients, which complements chemical fertilizers and support sustainable farming. Liquid formulations of microbial inoculants typically are broth based, oil, or polymer-based products. Biofertilizer in form of liquid broth is a special formulation containing large number of desired microorganisms with maximum shelf life and minimum contamination.

Methods For present study, Soil survey and isolation of microbes was done. Results were showing that the growth of microbial inoculants on yeast extract MMannitol Agar (YEMA), Jensen’s Media, Mannitol Ashby agar medium, Pikovskaya’s (PVK) medium, NBRIP National Botanical Research Institutes’s medium, and Azospirillum media, Bunt and Rovira agar medium prominently very effective for carrier based liquid biofertilizers.

Results Isolation of Rhizobium, Azotobactor, Azospirillum, phosphate solubilizing bacteria (PSB) and different formulation are prepared at laboratory scale and carrier based microbial inoculants were also prepared and having very good shelf life.

Conclusions Different formulation of liquid inoculants are recomended for farming. Nitrogen fixer, phosphate solubilizer, potassium solubiliser, zinc solubiliser play important role in next generation farming.
