Extract

The efficiency of ten different strains of Rhizobium trifolii was studied with nitrogen free quartz sand cultures of red clover during three consecutive years.

(1) In the first season, distinct differences were noted in the size and nitrogen contents of the crops produced, after inoculation with ten various bacterial strains. These differences remained clearly discernible throughout the experimental period of 3 years: the individuality of the strains had not materially changed during this time.

(2) Reinoculation with the most efficient strain during the third year did not affect the plants.

(3) The loss of plants in winter was greatest in the jars which were inoculated with weak strains.
