The present invention relates to eco-friendly compositions and methods for providing plant growth enhancing formulations comprising mixtures of microbial isolates. The microbial consortium is developed for customized solution of soil health related problem such as with plant growth promoting properties including root and shoot length elongation, early and high germination rate, high yield, decrease in soil pathogenic load and increase soil micro and macronutrient status. These specifically designed polymicrobial formulations would further provide protection against plant pathogens lowering the need for nitrogen containing fertilizers, solubilize minerals, protect plants against pathogens, and make available to the plant valuable nutrients, such as phosphate, thus reducing and eliminating the need for using chemical fertilizers and chemical pesticides.
