Liquid formulations (LFs) are being developed that ensure more quality over the conventional carrier based biofertilizers inaugurating a new era in the Biological input technology. These liquid formulations facilitate long shelf life (up to 2 years), minimum contamination, carrier free activity, handling comfort, storage and transport convenience, easy quality control, enhanced export potentials and are preferred by the farmer community as well as manufacturers.In agricultural eco-system, microorganisms have vital role in fixing/ solubilizing/mobilizing/nutrient recycling. These microorganisms occur in soils naturally, but their populations are often scanty. In order to increase the crop yield, the desired microbes from rhizosphere are isolated and artificially cultured in adequate count and mixed with suitable carriers or as they are in suitable combinations
