P-BCL800 Biochar Fertilizer Effects on Chili Yield and Soil Properties

A dataset from a pot experiment evaluating a tobacco stem-derived biochar-based phosphate fertilizer (P-BCL800). The data includes results from six treatments comparing P-BCL800 substitutions to traditional fertilizer, measuring effects on chili yield, soil pH, phosphorus availability, and microbial diversity. The dataset was authored by Xiaoqing Zhu and last updated on 2026-05-14.

Use Cases

• Compare crop yield outcomes based on different biochar fertilizer substitution rates mentioned in the description
• Analyze the relationship between soil pH and phosphorus availability under different fertilizer treatments
• Study shifts in microbial community structure, such as the relative abundance of Proteobacteria and Actinobacteria, in response to soil amendments
• Model the optimal biochar substitution rate for maximizing chili yield and soil health

Strengths

• Includes results from six distinct experimental treatments, allowing for comparative analysis
• Measures multiple outcome variables: yield (up to 382 g), photosynthetic efficiency, soil pH, P availability, and microbial activity
• Dataset is openly licensed under CC-BY-4.0

Limitations

• Row count and column-level documentation are unknown, which limits suitability assessment
• The dataset is small (535.5 KB), indicating a limited experimental scope
• Geographic context for the acidic red soil is not specified
