Soil Bacterial Communities and C/N/S Cycling in a Valley Landfill

144 soil samples were collected from a valley-type landfill in southern Sichuan, China, across three hydrological seasons. The data examines bacterial community responses, including relative abundances of phyla like Proteobacteria and Acidobacteriota, to leachate exposure and factors such as pH and Pb. It was authored by Guangli Xiao to investigate multi-factor interactions affecting biogeochemical cycles.

Use Cases

• Analyze the relationship between soil pH and the relative abundance of dominant phyla like Proteobacteria and Acidobacteriota across different seasons.
• Model the negative regulatory effect of soil Pb levels on bacterial community diversity and C/N/S cycling functions using path modeling techniques.
• Investigate how distance from the landfill serves as a predictor for bacterial community structure and functional profiles in random forest analyses.
• Compare bacterial co-occurrence network complexity and diversity between leachate-affected sites and clean soil during normal and wet seasons.

Strengths

• Contains data from 144 soil samples, providing a substantial basis for statistical analysis.
• Samples were collected across three distinct hydrological seasons (dry, normal, wet), enabling temporal comparison.
• The study quantifies specific changes, such as a >200% increase in Proteobacteria and a 50% reduction in Chloroflexi due to leachate exposure.
• Employs multiple analytical methods including redundancy analysis, PLS-PM, and random forest to identify key regulatory factors.

Limitations

• The dataset is contained within a 969.5 KB DOCX file, which is a small, document-based format not optimized for direct computational analysis.
• Data is from a single landfill site in southern Sichuan, China, limiting geographical generalizability.
• Specific column names, row counts for tabular data, and sample data are unavailable, hindering immediate understanding of the data structure.
