Other claims from this paper (7)
- Observation Forest soil had higher concentrations of tested elements other than Mg than field soil.
- Intervention effect Autoclaving yielded higher extractable nutrient amounts among variable sterilization effects.
- Intervention effect Disturbed soil raised foliar N, P and Ca compared with other treatments.
- Intervention effect Seedling nutrient concentrations were usually higher after autoclaving than fumigation.
- Intervention effect Soil disturbance increased seedling height growth in field soil.
- Intervention effect Soil disturbance did not increase seedling height growth in forest soil.
- Mechanism The authors infer reduced field soil bulk density helps black walnut growth.
