Straw Decomposition Data from Tillage and Microbial Inoculant Field Experiments

Field experiment data from a study on maize straw decomposition in cold, arid northern China. The research integrates field tillage and in-situ micro-zone degradation experiments to explore the mechanism of microbial inoculant M44 combined with three straw returning methods. The dataset was authored by Wenshan Zhao and uploaded to figshare in April 2026.

Use Cases

• Model straw degradation rates based on tillage method and microbial inoculant application.
• Analyze relationships between key microbial taxa (e.g., Pseudoxanthomonas, Streptomyces) and extracellular enzyme activity.
• Compare the driving pathways of straw degradation under different treatments using PLS-PM model insights.
• Study the hierarchical interaction mechanism of 'key microorganisms—bacterial community structure—extracellular enzyme activity—straw degradation'.

Strengths

• Results include specific quantitative improvements: straw degradation rate increased by 2.33–9.81 percentage points and half-life shortened by 20.7–62.8 days.
• The study identifies concrete key functional microbial taxa (e.g., Pseudoxanthomonas, Devosia) and specific ASVs (e.g., ASV6, ASV12).
• Experimental design integrates three distinct straw returning methods (DPR, SSR, NTR) with a microbial inoculant.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is a single DOCX file of 886.2 KB, suggesting limited scope and potentially summarized results rather than raw observational data.
