Other claims from this paper (9)
- Intervention effect Milk and phosphate supplements with the inoculum did not overcome the difficulty of successful seed inoculation.
- Intervention effect Heavier rates of inoculation gave a reasonable degree of nodulation even in untreated soils.
- Association Clover rhizobial population was relatively low in Lismore krasnozem soils.
- Observation Added clover rhizobial cells did not persist or multiply at a rate comparable with other soils and conditions.
- Intervention effect Raising soil pH to c. 7 with Ca(OH)2 or CaCO3 markedly improved survival and multiplication of clover rhizobia.
- Intervention effect A small rise in soil pH gave appreciable improvement for clover rhizobia.
- Association The relative performance of strains can be affected by soil and host factors.
- Association Competition for nodulation need not be related to competition for growth.
- Association Competition by native strains can be an important factor contributing to success or failure with added inoculum.
