Deep application of organic amendments and biostimulants for enhanced soil biological acti

Dewen Qiao's dataset from a two-year field experiment evaluates deep injection of organic amendments and biostimulants on soil biological activity and maize productivity. The data includes depth-resolved soil nutrient pools, mid-infrared spectroscopic signatures, extracellular enzyme kinetics, satellite-derived canopy dynamics, and maize yield responses. It was last updated on 2026-04 24 and is shared under a CC-BY-4.0 license.

Use Cases

• Modeling maize yield responses based on deep soil amendment treatments.
• Analyzing relationships between subsoil organic carbon and enzyme activity based on depth-resolved measurements.
• Investigating plant physiological functioning pathways based on satellite-derived canopy dynamics.
• Comparing the effects of liquid digestate versus humic acid on soil phosphorus availability.

Strengths

• Dataset is based on a two-year field experiment, providing temporal depth.
• Integrates multiple data layers: soil chemistry, spectroscopy, enzyme kinetics, satellite imagery, and yield data.
• Results include specific quantitative findings, such as a 55-61% increase in subsoil organic carbon from humic acid treatments.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small (51.8 KB), indicating limited scope or highly summarized data.
