Therefore, factors affecting the survival or metabolism o f any o f the nitrogenfixing organisms would probably affect competition between plants with different nitrogen requirements, and thus the rate o f succession in infertile old fields. Several investigators demonstrated that certain microorganisms in the soil are inhibitory to Azotobacter and Rhizobium (Konishi, 1931; Iuzhina, 1958; Van der Merwe et ah, 1967). Others found that seeds and other plant parts were inhibitory to Rhizobium (Thorne and Brown, 1937; Bowen, 1961; Fottrell et al, 1964), and Elkan (1961) reported that a non-nodulating soybean strain significandy decreased the number o f nodules produced on its normally nodulating almost III.
