Description
Eight factorial treatments, including three CO2 levels (+0, +150, +300 ppm), three temperature levels (+0, +1.5, +3°C), and drought, were applied in a montane grassland experiment in Austria during 2017. The dataset contains soil nitrogen cycling rates, such as gross protein depolymerization and nitrification, measured via isotope pool dilution across three harvest dates. It provides a detailed record for analyzing interactive effects of multiple climate change drivers on belowground nutrient processes.
Use Cases
Modeling interactive effects of CO2, temperature, and drought on soil nitrogen transformation rates based on the eight treatment levels.
Analyzing seasonal dynamics of nitrogen cycling processes across the three harvest dates in May, July, and October.
Comparing gross rates of specific processes like protein depolymerization and free amino acid uptake between control and drought conditions.
Investigating relationships between treatment factors (e.g., CO2_ppm, Temp_C) and measured response variables like mineralization and nitrification.
Strengths
Data originates from a controlled multi-factorial experiment with eight explicitly defined treatment combinations.
Measurements include multiple specific nitrogen cycling rates (e.g., Prot_depoly, Nitrification) using the isotope pool dilution method.
Temporal resolution includes three distinct harvests within a single growing season (2017).
Limitations
Key metadata such as row count, file size, and specific column count are unknown across all sources.
The dataset's temporal coverage is limited to a single year (2017), which may not capture interannual variability.
Documentation references a companion paper that is not yet linked, indicating potential incomplete contextual information.
