Grassland Nitrogen Addition and Microcosm Experiments Data

Nana Liu published a dataset on figshare containing data from field nitrogen addition experiments in grasslands and related microcosm experiments in a greenhouse. The dataset includes multiple Excel sheets covering plant aboveground biomass, species richness, soil chemistry, and various plant physiological and morphological measurements. It was last updated on 2026-05-25 and is licensed under CC-BY-4.0.

Use Cases

• Modeling the relationship between nitrogen addition and plant aboveground biomass based on field experiment data
• Analyzing the correlation between soil pH and concentrations of soil cations like potassium and calcium based on soil chemistry data
• Investigating the effects of pH treatments on plant survival rate and root morphology based on greenhouse microcosm data

Strengths

• Dataset is structured into seven distinct Excel sheets, each focusing on a specific experimental aspect like soil chemistry or plant biomass.
• The description provides a detailed breakdown of the variables measured in each sheet, such as soil pH, root surface area, and photosynthetic rate.

Limitations

• The row count is unknown, which may limit suitability assessment for large-scale modeling.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small in size (43.9 KB), indicating a limited scope of data points.
