Biochar Effects on Cucumber Yield and Soil Microbiota Under Continuous Cropping

Six biochar application rates (0 to 40 t ha⁻¹) were tested on cucumber crops in a continuous cropping system. The dataset, authored by Guoping Xue and last updated in May 2026, likely contains measurements of yield, soil properties, enzyme activities, and microbial/metabolite profiles from metagenomic and metabolomic analyses. Biochar treatments improved cucumber yield by 20%-50% and altered soil nutrient cycling and bacterial communities.

Use Cases

• Modeling the relationship between biochar application rates and crop yield improvements based on the six tested rates.
• Analyzing shifts in key soil bacterial phyla (e.g., Actinobacteria, Bacteroidetes) in response to soil amendments.
• Investigating the upregulation of secondary metabolic pathways (e.g., phenylpropanoid biosynthesis) under medium to high biochar treatments.
• Studying the correlation between soil physicochemical properties (e.g., total nitrogen, available phosphorus) and enzymatic activities (e.g., urease, sucrase).

Strengths

• Includes six distinct biochar application rates (0, 5, 10, 20, 30, 40 t ha⁻¹) for comparative analysis.
• Reports specific yield improvements of 20%-50% and identifies peak quality indicators (Vitamin C, soluble protein) at the C20 treatment.
• Integrates multiple analytical methods (metagenomics and metabolomics) to explore microbial and metabolite coupling.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Geographic scope is limited to facility systems in the cold and arid northern regions of China.
