The value of unsterilized soil‐agar slopes for studying the effect of chemical and biological characteristics of soil on the rhizobia‐plant relationships has been demonstrated by examining the characteristics of 4 strains of Rhizobium meliloti isolated from salt‐affected soils of Greece. The technique enabled information to be obtained on: the survival of indigenous rhizobia and bacteria; the survival of rhizobia added to soil; the antagonistic‐symbiotic effects, and the effectiveness of inoculation on nitrogen fixation to be closely followed.
