Short summary
Whilst previous studies have focused on the impact of nitrogen on microbe-mediated methane flux, little is known about the role of phosphorus and potassium. Here, we report that P-deficiency-induced changes in soil properties and plant growth state reduced CH4 flux from paddy soil, which was closely correlated with the abundance and community structures of active methanogens and methanotrophs. These results can benefit the effective nutrient management of paddy fields to reduce methane emission.
