Soil Properties and Bacterial Communities Under Tequila Vinasse Irrigation

A one-year field case study in Amatitán, Jalisco, Mexico, compares seven tequila vinasse irrigation treatments against three controls. The dataset includes quarterly measurements of soil physicochemical properties and bacterial community analysis via 16S rRNA sequencing. Results detail changes in organic matter, heavy metals, and bacterial taxa like Actinomycetota and Pseudomonadota.

Use Cases

• Analyze correlations between heavy metal levels (As, Cd, Pb, Cu, Cr, Ni, Zn) and bacterial genera like Kocuria or Amphiplicatus from 16S rRNA sequencing data.
• Model the impact of tequila vinasse dose (1-30 L/m²/month) and type (raw vs. neutralized) on soil pH, phosphorus (peaking at 1,231 mg/kg), and potassium.
• Compare bacterial community composition, specifically the relative abundance of Actinomycetota (36–47%) and Pseudomonadota (21–27%), across different irrigation treatments and controls.
• Assess the relationship between irrigation treatments and beneficial bacteria such as Conexibacter, Bradyrhizobium, and nitrogen-fixing genera like Micromonospora and Frankia.

Strengths

• Data originates from a controlled one-year field study with seven distinct tequila vinasse treatments and three control groups, providing a structured experimental comparison.
• Includes detailed bacterial community analysis via 16S rRNA sequencing, reporting phylum-level abundances like Actinomycetota (36–47%) and Pseudomonadota (21–27%).
• Reports specific physicochemical measurements, such as soil pH rising from 6.4 to 6.5 and phosphorus peaking at 1,231 mg/kg in August.

Limitations

• The dataset is contained within a 17.2 MB DOCX file, which may require parsing to extract structured data for analysis, unlike a ready-to-use CSV or database.
• As a single case study from one location (Amatitán, Jalisco, Mexico), findings may not generalize to other soils or climates.
• Temporal coverage is limited to one year, which may not capture long-term effects of vinasse irrigation on heavy metal accumulation or microbial shifts.
