LBA-ECO ND-07: Nitric Oxide Flux from Fertilized Cerrado Soils

LBA-ECO ND-07 reports soil nitric oxide flux, moisture, and nutrient concentrations from a long-term fertilization experiment in Brazil's Cerrado. Measurements were taken from March to November 2004 on plots that had received nitrogen and phosphorus treatments since 1998. This dataset supports research into the long-term atmospheric effects of nutrient addition in native tropical savanna ecosystems.

Use Cases

• Modeling soil-atmosphere nitrogen oxide fluxes based on fertilization treatment and soil moisture data.
• Analyzing long-term effects of nutrient addition (N and N+P) on soil nitrate and ammonium concentrations.
• Studying biogeochemical cycles in the Cerrado ecosystem using temporally sampled field measurements.

Strengths

• Provides data from a controlled, long-term experiment with treatments ongoing since 1998.
• Covers a defined temporal sampling period from March 26 to November 25, 2004.
• Dataset is hosted on multiple authoritative platforms (NASA, Data.gov), indicating curation and importance.

Limitations

• Column names and exact row counts are not provided in any source, limiting immediate usability.
• Metadata shows a conflict: one platform lists a last update date in 2026, while another shows 2004, suggesting possible metadata errors.
• The specific license is listed only as 'other-license-specified', requiring further investigation for reuse.

Provenance

Source

National Aeronautics and Space Administration (NASA), collected at the Ecological Reserve of the Brazilian Institute of Geography and Statistic (IBGE), Brasilia.

Collection Method

Field measurements and sample collection from control and fertilized experimental plots.

Time Range

1998 (treatment start) to 2004 (sampling period). Primary sampling dates: March 26, 2004 to November 25, -2004.

Freshness

2026-04-10 01:43:17.719577 (Data.gov), but this conflicts with the 2004 end date of the actual study.
