Other claims from this paper (12)
- Intervention effect Manure C inputs significantly increased soil dissolved organic carbon content in the maize field experiment.
- Intervention effect Manure C inputs induced a shift in microbial community composition from oligotrophic (Acidobacteria) to copiotrophic taxa (Proteobacteria, Bacteroidetes, Myxococcota).
- Intervention effect Manure C inputs were accompanied by increased microbial biomass P.
- Intervention effect Manure amendment significantly raised the soil C:P ratio.
- Intervention effect The microbial C:P ratio remained relatively stable across treatments despite manure amendment.
- Mechanism The induced C:P imbalance intensified microbial P limitation.
- Intervention effect Manure amendment enhanced the bioavailable P pool.
- Intervention effect Manure amendment increased plant P acquisition.
- Intervention effect P-based manure amendment increased maize yield by 12% relative to full chemical fertilization.
- Intervention effect P-based manure amendment improved P fertilizer recovery efficiency from 81.34% to 97.06% relative to full chemical fertilization.
- Intervention effect P-based manure amendment reduced soil P accumulation from 7.35 to 1.15 kg P ha −1 year −1 relative to full chemical fertilization.
- Mechanism The authors suggest that manure-induced stoichiometric imbalance triggers a priming effect on indigenous microbial P mobilization.
