Number and Effectiveness of Pea Rhizobia in Danish Soils

K.C. Engvild

    Research output: Contribution to journalJournal articleResearch


    Most of 44 Danish soils tested contain between 1000 and 10 000 pea rhizobia (Rhizobium leguminosarum biovar viceae) per gram. Pea rhizobia were not detected in acid moor and forest soils. Only one case of failed nodulation in peas in the field has been noted, in spots in a reclaimed sandy heath moor at pH 4.7. Soil suspensions of nine of the soils were tested as inoculum in large outdoor pot cultures of peas grown to maturity in nitrogen free vermiculture. One soil approached the effectiveness of commercial inoculants, and four soils were quite effective. Two reclaimed soils and two of the three noncultivated soils showed low effectiveness.
