Other claims from this paper (10)
- Intervention effect Liming to pHw 4.83 benefited shoot mass, shoot N uptake, nodule number, and acetylene reduction at three weeks.
- Intervention effect Root mass and length did not benefit from liming at three weeks.
- Association Shoot mass, nitrogen uptake, and nodule number increased approximately linearly with soil pH at five and seven weeks.
- Intervention effect Root mass responded positively to liming at later times.
- Intervention effect Root length did not respond to liming at later times.
- Association Soil chemical properties correlated significantly with shoot mass and nitrogen uptake.
- Association The soil property correlations improved with time but remained below 0.80 at seven weeks.
- Observation Asymbiotic plants had similar shoot responses at different times, indicating different growth rates.
- Intervention effect Rhizobial inoculum level significantly altered the outcome of symbiosis.
- Method / resource The model system demonstrated utility for studying early liming effects on white clover symbiosis.
