7075. Vandecaveye, S.C.. 1927. Effect of moisture, temperature, and other climatic conditions on R. leguminosarum in the soil.. Soil Sci. 23:355-362.
Looked at Rhizobium survival in the Palouse, particularly during the hot, dry months. R. leguminosarum had no problem surviving wide extremes of soil moisture, while soil flooding was detrimental to them. Rhizobium survival should be 10-15 years or more without a host plant. Dust storms did distribute Rhizobium, but not enough to insure uniform nodulation.

7161. Vandecaveye, S.C. and W.H. Fuller. 1941. Studies of different cultures of Rhizobium leguminosarum and of gypsum and straw for seed pea production.. Iowa St. College Journal of Sci. 15(4):415-423.
Tested 7 cultures of Rhizobium for nodulation and yield of Alaska seed peas. Also did a pot study with wheat straw and gypsum amendments. The field soil had never had peas before, but contained sufficient Rhizobium to inoculate peas. Seed inoculation tended to increase yields, but no culture was a sufficiently good N fixer to insure vigorous growth on soils low in available N. Soil amendments did not affect nodulation or growth. Yield differences were primarily due to variation in soil productivity.
