| Abstract: | Abstract The enrichment of 15N in the nodules of some N2-fixing leguminous plants is an interesting finding (Shearer et al. 1982). The extent of 15N enrichment differed depending on the plant species (Shearer et al. 1982; Yoneyama 1987) and bacterial strains (Steele et al. 1983), and in soybeans it was apparently related to the nitrogen fixation efficiency (Shearer et al. 1984) |
