Biochar Application Effects on Urban Farm Soil Properties in West Sacramento

West Sacramento, California, USA, is the location for a field experiment measuring the effects of biochar applied at 0, 10, 20, and 30 tons per hectare on soil physical, chemical, and biological indicators. The dataset, authored by Si Gao and last updated in May 2026, contains results from compost-amended plots under corn and squash production, analyzing properties like aggregate stability, soil respiration, microbial biomass, and enzyme activities.

Use Cases

• Modeling the dose-response relationship of biochar on soil microbial activity based on application rates.
• Analyzing the correlation between microbial indicators and nutrient availability in amended soils.
• Comparing soil physical structure responses (e.g., aggregate stability) to different biochar application levels.
• Investigating crop-specific differences in nutrient pools and microbial biomass under biochar treatments.

Strengths

• Data is from a controlled field experiment with four distinct biochar application rates (0, 10, 20, 30 t ha⁻¹).
• Analysis includes multiple functional domains: soil physical structure, microbial activity, and biochemical properties.
• Results are derived from late-season soil sampling in a real-world urban agricultural setting.

Limitations

• Dataset size is 198.6 KB, indicating a very limited scope and likely small sample size.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for statistical modeling.
