Studies of Rhizobium meliloti isolated from salt‐affected soils

SUMMARY Rhizobium meliloti strains have been isolated from salt‐affected, non‐cultivated soils of Greece. The effectiveness of the isolates was investigated in test‐tubes using nitrogen‐free salts agar or soil. In the latter case a new simple and rapid technique was used during which plants of Medicago saliva were grown in large test‐tubes containing salt‐affected soil under controlled sterile conditions. Field trial measurements in salt‐affected soils indicate a good response to inoculation.
