Abstract
Abstract Experiments were conducted to study the effect of sodium molybdate on soybean rhizobia when combined in a peat carrier medium in proportions which would ordinarily be used on soybean seeds. Laboratory tests showed a 99% kill of rhizobia within 4 days and no subsequent recovery. Survival of soybean rhizobia was not improved by incorporating the molybdenum into peat or charcoal premixes before blending with the rhizobia‐containing inoculant. Field tests with ‘Chippewa’ soybeans planted in a soil virgin to soybeans confirmed that the inoculant‐molybdenum combinations contained too few rhizobia to bring about effective nodulation even when used as early as 3 weeks following preparation. Poor nodulation was reflected in low yields. When sodium molybdate was mixed with the inoculant immediately before application to the seed at planting time, excellent nodulation and increased yields were obtained.
