Other claims from this paper (12)
- Intervention effect Biochar application increased root biomass by 32%.
- Intervention effect Biochar application increased root volume by 29%.
- Intervention effect Biochar application increased root surface area by 39%.
- Intervention effect Biochar application increased root length by 52%, much more than root diameter.
- Intervention effect Biochar application increased the number of root tips by 17%.
- Intervention effect Biochar application increased root diameter by 9.9%, much less than root length and tip number.
- Intervention effect Biochar application did not change root N concentration.
- Intervention effect Biochar application significantly increased root P concentration by 22%, particularly when combined with N fertilization.
- Intervention effect Biochar application significantly increased the number of root nodules by 25%.
- Association Responses of root traits to biochar were generally greater in annual plants than in perennial plants.
- Association Responses of root traits to biochar were affected by soil texture and pH values.
- Mechanism The pattern of root increases suggests biochar benefits root morphological development to alleviate plant nutrient and water deficiency rather than to maximize biomass accumulation.
