Studies of Rhizobium meliloti isolated from salt-affected soils

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.
