- Intervention effect N fertilization highly increased soil mineral N in continuous peanut monoculture.
- Intervention effect N fertilization decreased the soil C/N ratio in continuous peanut monoculture.
- Intervention effect Peanut yields were unchanged by N fertilization.
- Intervention effect Root biomass of peanut was stimulated only at N120.
- Intervention effect N fertilization reduced rhizosphere β-1,4-glucosidase and polyphenol oxidase activities across application rates.
- Intervention effect β-1,4-cellobiohydrolase activity increased only at N120 in peanut rhizosphere.
- Intervention effect Bacterial alpha diversity in the peanut rhizosphere was unchanged by N fertilization relative to N0.
- Intervention effect Fungal richness and diversity increased at N60 and N120 relative to N0.
- Intervention effect Relative abundance of Acidobacteria decreased under N fertilization in peanut rhizosphere.
- Intervention effect Alphaproteobacteria and Gammaproteobacteria increased at N60 and N120 in peanut rhizosphere.
- Intervention effect The pathogenic Sordariomycetes was inhibited under N fertilization in peanut rhizosphere.
- Intervention effect The saprotrophic Agaricomycetes was promoted by N fertilization regardless of rate in peanut rhizosphere.
- Intervention effect N fertilization slightly increased soil respiration at N60.
- Intervention effect N fertilization significantly increased soil respiration at N120.
- Mechanism The increase in soil respiration under N fertilization is attributed to promotion of cellulose-related microbes.
- Intervention effect N fertilization slightly decreased soil respiration at N180, likely due to carbon limitation.
