Salvia Miltiorrhiza Growth and Rhizosphere Microbiome Data Under Humic Acid Treatments

A pot experiment dataset from 2026 by Zhe Wang investigates the effects of humic acid soil amendments on Salvia miltiorrhiza. It includes measurements of plant biomass, bioactive compound concentrations, soil enzyme activities, and metagenomic analysis of the rhizosphere microbiome. The data compares three application rates against a control to explore mechanisms for improving soil quality and plant productivity.

Use Cases

• Modeling the relationship between humic acid application rates and plant biomass based on reported percentage increases
• Analyzing shifts in microbial community composition based on the enrichment of specific taxa like Luteitalea and Nitrospira
• Studying the correlation between soil enzyme activity (e.g., β-glucosidase) and the abundance of functional genes for nutrient cycling
• Investigating the impact of soil amendments on the concentration of medicinal compounds like tanshinone IIA and salvianolic acid B

Strengths

• Includes specific, quantified results such as root biomass increases of up to 52.59% and tanshinone IIA increases of up to 81.46%
• Provides comparative metagenomic analysis detailing enrichment of specific microbial taxa and functional genes
• Uses a controlled experimental design with three treatment levels and a conventional fertilization control

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data is from a single pot experiment; generalizability to field conditions requires validation as noted in the description
