Twenty strains of Rhizobium trifolii were grown separately and equal portions were compounded into a single mixed humus culture. Twelve species of Trifolium were inoculated with this mixed culture, with a single good strain, and with a poor strain. On Trifolium incarnatum and T. fragiferum , the mixed culture was significantly better than the single good strain culture. On T. subterraneum, T. hirtum , and T. lappaceum , the single good strain was significantly better than the mixed culture. On the seven other species, T. repens, T. repens var. ladino, T. pratense, T. hybridum, T. nigrescens, T. glomeratum , and T. resupinatum , no significant differences were found between the single good strain and the mixed culture. The presence of poor strains in the mixed culture apparently had no harmful effect on its efficiency to inoculate the 12 different species of true clovers.
