Grassland Nitrogen Loss Under Altered Precipitation Frequency

Experimental data from a two-year study on soil inorganic nitrogen loss across a Leymus chinensis grassland degradation gradient. The research tested moderate and extreme decreases in precipitation frequency to understand the magnitude and mechanisms of nitrogen losses. The dataset was authored by Tianxue Yang and uploaded to figshare in April 2026.

Use Cases

• Analyze the relationship between precipitation frequency levels and measured soil inorganic nitrogen loss.
• Compare nitrogen loss metrics across different states of the Leymus chinensis grassland degradation gradient.
• Model the influence of key biogeochemical pathway variables on nitrogen loss outcomes.

Strengths

• Data from a controlled two-year experimental study.
• Explicitly tests two precipitation frequency treatments (moderate and extreme decrease) across a degradation gradient.
• Published under a permissive CC-BY-4.0 license.

Limitations

• Dataset is very small at 28.3 KB, indicating limited scope and likely low row count.
• Specific sample size, column names, and measured variables are not provided in the description.
• Geographic location of the grassland study site is unknown.
