Soil analysis reveals rice straw enhances microbial communities, indicating improved degradation capacity.

This research aims to investigate the impact of rice straw incorporation on microbial communities in soil.
Soil samples were collected from rice fields with annual straw incorporation in Fujian Province.
A straw burial pot experiment was conducted to analyze microbial community compositions.
High-throughput sequencing analyzed bacterial and fungal communities in soil samples.
The degradation potential of soil microbial communities towards rice straw was evaluated.
Dominant bacterial phyla included Proteobacteria, Actinobacteriota, Firmicutes, and Chloroflexi.
Fungal phyla Ascomycota and Basidiomycota were identified as predominant.
Bacillus showed a positive correlation with straw degradation, while Zopfiella and Chaetomium correlated positively with both straw degradation and soil pH.
Strain Chaetomium sp. (designated PC1) reached a rice straw degradation rate of 49.13%.

Zhang et al. (2025) studied this question.
