- Intervention effect In the PK treatment, rapeseed yield decreased on average 33.1% per year compared with NPK.
- Intervention effect In the NK treatment, rice yield decreased on average 18.1% per year compared with NPK.
- Intervention effect In the NK treatment, rapeseed yield decreased on average 54.8% per year compared with NPK.
- Intervention effect In the NP treatment, rice yield decreased on average 6.4% per year compared with NPK.
- Intervention effect In the NP treatment, rapeseed yield decreased on average 16.0% per year compared with NPK.
- Intervention effect Long-term fertilization significantly changed soil chemical properties, especially pH and available K content.
- Intervention effect The NK treatment increased soil microbial composition and diversity compared with NPK fertilization.
- Intervention effect The PK and NP treatments had a reverse impact on soil microbial composition and diversity compared with NPK fertilization.
- Association Available K, pH and slowly available K were closely related to alterations of the dominant bacterial community.
- Association Olsen-P, slowly available K and pH were significantly correlated with the fungal community.
- Association Soil properties changed by fertilization had a more direct effect on crop yield than the microbial community.
- Association The bacterial group had a higher influence than the fungal group on crop yield.
- Recommendation A balanced NPK fertilization is an effective management strategy for soil biological fertility and sustainable crop yield.
