Brazilian Forest Chronosequence Data: Nutrient and Gas Flux Analysis

Litterfall and soil data from forest chronosequences in Para, Brazil, provide nutrient concentrations and trace gas flux measurements. The dataset includes five files covering nitrogen, phosphorus, potassium, calcium, magnesium, carbon, and stable isotopes from leaves and soil. Samples were collected between 2000 and 2005 by ORNL_CLOUD.

Use Cases

• Analyzing nutrient concentrations (N, P, K, Ca, Mg) in litterfall across forest age gradients.
• Studying soil trace gas fluxes measured over 10 sampling periods across wet and dry seasons.
• Investigating carbon and nitrogen stable isotope ratios (delta C13, delta N15) in dominant forest species.
• Correlating soil physical and chemical characteristics with forest age and litterfall chemistry.

Strengths

• Includes multi-year temporal coverage from October 2000 to February 2005.
• Provides data from two distinct study sites (Sao Francisco do Para and Capitao Poco) for comparison.
• Contains measurements across both wet and dry seasons, with 5 sampling periods each for gas fluxes.

Limitations

• Specific row counts, column names, and file sizes are not provided by any source.
• Conflicting last updated dates: one source reports 2026-03-13, another reports 2005-01 31.
