Abstract
Some nodule bacteria do not tolerate acid soils. A study was initiated to determine if Rhizobium japonicum could adapt to soil acidity and therefore become more effective nitrogen-fixers in association with soybeans (Glycine max L. Merr.) grown in acidic soils. Nodules were obtained from soybeans grown in fields where the crop had been planted for at least 5 years in soil with pH near 5 6 or 7. The nodular material was used for inoculation of soybeans in a factorial experiment grown in methyl bromide fumigated soil obtained from the same fields as the inoculum. Nitrogenase activity and plant weight were used for evaluating the treatment effects. The results indicated that the nodular bacteria did not adapt to a given soil pH. Soybeans grown in soil at pH 6 grew best regardless of whether inoculum was from plants grown at pH 5 6 or 7. In acid soil inoculum from soils at pH 5 was no better than those from pH 6 or 7
