Alpine Wetland Grassland Experiment Data on Grazing and Fertilization

A split-plot field experiment in alpine wetland meadows measured plant functional traits and productivity under different grazing and fertilization regimes. The dataset includes community-level leaf traits, soil properties, biodiversity metrics, and aboveground biomass. Management factors alone explained about 45% of biomass variation.

Use Cases

• Analyze the relationship between community-weighted leaf area (CWM_LA) and specific leaf area (SLA) under winter-only versus year-round grazing regimes.
• Model the effect of available phosphorus, total phosphorus, and soil pH on aboveground biomass (AGB) using random forest techniques.
• Investigate how nitrogen addition levels (0, 5, and 10 g N m–2yr–1) influence leaf dry matter content (LDMC) and SLA in grasses contingent on grazing.
• Use structural equation modeling to test the direct negative effect of fertilization (b = –0.326) on AGB and its indirect pathways through soil nutrients and plant diversity.

Strengths

• Data originates from a controlled split-plot field experiment with defined nitrogen addition levels (0, 5, and 10 g N m–2yr–1).
• Analysis shows management factors alone explained about 45% of biomass variation, indicating strong experimental signal.
• Includes multiple measured variable types: leaf traits, soil physicochemical properties, biodiversity metrics, and aboveground biomass.

Limitations

• The dataset is small in file size (951.4 KB), suggesting limited raw data or a primary document format rather than a large structured table.
• Unknown row and column counts prevent assessment of sample size and feature dimensionality for machine learning.
• Data is contained in a DOCX file, which is not a standard structured data format and may require extraction for analysis.
