Current commercial rhizobia biofertilizers contain generic bacteria and perform erratically in different soil conditions. The aim of this project is to create a new generation of rhizobial biofertilizers by designing a solution that offers an optimal i) crop ii) soil and iii) biofertilizer match. Our approach consists of a unique rhizobial soil test followed by high-throughput identification of elite rhizobia in the legume of interest. The rhizobial formulation can be produced as a valuable product because it is a precise, predictable, and efficient biofertilizer.
