| description | 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 N z-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
(C zH z - C zH 4reduction) and plant weight were usedfor evaluating the treatment effects. The results
seem to indicate 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. |
