Tobacco Field Experiment Data on Soil Disinfestation in Guizhou Karst Regions

A field experiment conducted in continuous cropping tobacco fields in Bijie City, Guizhou Province evaluated Reductive Soil Disinfestation (RSD) treatments. The dataset, authored by Mengjiao Ding and last updated in May 2026, likely contains measurements of soil physicochemical properties, microbial community structure, tobacco growth, and disease incidence. The study assessed RSD treatments with different organic material inputs combined with reduced chemical fertilizer.

Use Cases

• Modeling the relationship between soil pH, nutrient levels, and crop disease incidence based on described physicochemical properties.
• Analyzing shifts in soil microbial community structure and functional groups like Acidobacteriota and Bacillus in response to organic amendments.
• Evaluating the efficacy of different organic material input levels (0, 140, 280 kg per 667 m²) for controlling bacterial wilt and tobacco mosaic virus.
• Predicting crop health indicators, such as leaf potassium-to-chlorine ratio, based on soil treatment and microbial data.

Strengths

• Data is derived from a controlled field experiment with specific treatment levels (0, 140, and 280 kg organic material per 667 m²).
• Results include concrete efficacy metrics, such as a 93.3% reduction in bacterial wilt incidence and a 76.5% reduction in tobacco mosaic virus incidence for the high-input treatment.
• The dataset is published under a permissive CC-BY-4.0 license, facilitating reuse.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset's 132.6 KB size suggests a limited scope, potentially containing summary statistics rather than raw observational data.
