Nitrogen Addition and Cessation Effects on Meadow Steppe Carbohydrates

A 2026 study by Jie Yu analyzes non-structural carbohydrate (NSC) pools in a temperate meadow steppe under six nitrogen addition levels and after cessation. The dataset, sourced from a field experiment, measures community and functional-group NSC, soluble sugars, and starch responses to nitrogen enrichment and withdrawal.

Use Cases

• Model the relationship between nitrogen addition rate and community starch (ST) pool to identify saturation thresholds.
• Compare soluble sugars (SS) and starch (ST) component responses at the functional-group level before and after nitrogen cessation.
• Analyze shifts in the single-peak response pattern of NSC pools after three years of ceasing nitrogen addition.

Strengths

• Data from a controlled field experiment with six distinct nitrogen addition levels.
• Measures plant carbon status via three specific pools: total NSC, soluble sugars (SS), and starch (ST).
• Examines contrasting scenarios of continuous nitrogen enrichment and a three-year cessation period.

Limitations

• Data is presented in a 6.8 MB PDF, requiring extraction for computational analysis.
• Sample size and specific row/column counts are not provided in the available metadata.
• Geographic scope is limited to a single temperate meadow steppe site.
