Plant Responses to Zinc and Nitrogen in a Meadow Steppe

A decade-long field experiment in Inner Mongolia measured how zinc addition interacts with nitrogen enrichment and mowing to affect four dominant plant species. The dataset contains species-specific physiological responses, including growth, photosynthesis, and antioxidant activity metrics. LiXin Yu authored this work, supported by Chinese research foundations, with data last updated in April 2026.

Use Cases

• Analyze species-specific growth responses to nitrogen enrichment using biomass columns.
• Model the relationship between zinc addition and superoxide dismutase activity levels in legume species.
• Compare photosynthetic parameter columns against antioxidant parameter columns to determine their relative influence on plant performance.
• Investigate interactions between mowing treatment columns and nutrient addition treatments on plant physiological metrics.

Strengths

• Data from a decade-long controlled field experiment provides longitudinal insights.
• Compares physiological responses across four distinct plant species and functional groups.
• Explicitly measures the interaction of three treatments: zinc addition, nitrogen addition, and mowing.

Limitations

• The dataset is small at 44.1 KB, indicating limited sample size or number of measured variables.
• Findings are geographically specific to a single meadow steppe ecosystem in Inner Mongolia.
• Unknown row count and specific column structure limit immediate assessment of data volume.
