Evaluating Potentially Superior Rhizobium Strains in Soybeans
Legumes infected with the symbiotic bacterium Rhizobium obtain nitrogen from both soil N and N2. It would be economically advantageous to conserve existing soil N by increasing the proportion of N derived from symbiotic N2 fixation in legumes such as soybeans, if agronomic yields could be maintained. One method to achieve that goal is the identification of superior Rhizobium strains.
