Polymicrobial formulations for enhancing plant productivity

摘要

Described herein are eco-friendly formulations and methods for providing such formulations to plants. The formulations include mixtures of microbial isolates. In particular, numerous bacterial and fungal strains were isolated from a variety of soil types, from rhizospheres and from root nodules of leguminous plants, in designed combinations, for providing plant growth and plant productivity enhancing formulations. These specifically designed polymicrobial formulations provide protection against plant pathogens, lower 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.
