Other claims from this paper (14)
- Intervention effect Biochar amendment dose-dependently enhanced total fine root length of Rhododendron by 57.2–85.4%.
- Intervention effect Biochar amendment enhanced plant nitrogen use efficiency of Rhododendron by 94.2–199%.
- Intervention effect Biochar suppressed pathogenic fungi (Dactylonectria) in the Rhododendron soil.
- Intervention effect Biochar suppressed N-competing bacteria (Lysobacter) in the Rhododendron soil.
- Intervention effect Biochar enriched beneficial fungi (Condenascus) in the Rhododendron soil.
- Intervention effect Biochar enriched copiotrophic bacteria (Pseudomonas) in the Rhododendron soil.
- Intervention effect Biochar enhanced the abundance of ammonia-oxidizing bacteria (AOB) in the Rhododendron soil.
- Intervention effect Biochar reduced nirS gene abundance in the Rhododendron soil.
- Intervention effect Biochar increased potential nitrification in the Rhododendron soil.
- Intervention effect Biochar decreased denitrification activity in the Rhododendron soil.
- Intervention effect At higher application rates (4%–8%) biochar decreased the (nirS + nirK)/nosZ ratio, indicating a potential reduction in N2O emissions.
- Association Soil fertility was associated with AOB abundance in the Rhododendron soil (partial least squares path model).
- Association Soil pH was linked to nirS in the Rhododendron soil (partial least squares path model).
- Mechanism Both AOB-related and nirS-related pathways ultimately govern nitrogen use efficiency of Rhododendron (author interpretation).
