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

Cerrado soils in Brasilia, Brazil, were studied for nitric oxide emissions under nitrogen fertilization. The dataset contains measurements of soil nitric oxide flux, soil moisture, and nitrate and ammonium concentrations from control and fertilized plots. Data collection occurred from March to November 2004, following fertilization treatments that began in 1998.

Use Cases

• Modeling soil-atmosphere nitrogen oxide fluxes based on fertilization treatments.
• Analyzing the relationship between soil moisture and nitric oxide emissions in a tropical savanna.
• Studying the long-term effects of nitrogen and phosphorus addition on native Cerrado soil chemistry.

Strengths

• Provides a focused, long-term experimental context with fertilization treatments ongoing since 1998.
• Contains a coherent set of core soil and atmospheric measurements (NO flux, moisture, NO3, NH4) from a defined geographic location.

Limitations

• Column names and exact row count are unspecified, limiting precise assessment of data structure.
• Conflicting last-update dates (2004 vs. 2026) suggest metadata may not reflect the actual data's age.
• License is ambiguously specified as 'other-license-specified' without clear terms.
