Amazonian Soil Nutrient Dynamics Across Land Uses 1950-2001

Amazonia soil property measurements compiled from 39 studies on nutrient dynamics across natural forests and forest-derived land uses. The dataset was created by NASA to test five hypotheses about land-use change effects on soil chemistry. It covers research conducted over a 51-year period from 1950 to 2001.

Use Cases

• Testing hypotheses on changes in effective cation exchange capacity (ECEC) and exchangeable calcium after forest conversion.
• Analyzing trends in total carbon, nitrogen, and extractable phosphorus content following pasture establishment.
• Modeling nutrient recovery in secondary forests based on time since agricultural abandonment.
• Comparing soil nutrient conditions across tree-dominated systems like natural forests and plantations.
• Investigating relationships between soil nutrient pool sizes and nutrient utilization efficiency.

Strengths

• Data synthesis from 39 peer-reviewed studies provides a regional-scale perspective.
• Explicitly tests five established scientific hypotheses on land-use change effects.
• Covers a multi-decade time range (1950-2001) of research.
• Compiled by a major research organization (NASA) as part of the LBA-ECO project.

Limitations

• Exact row count, column names, and file size are not provided by any source.
• Conflicting last-update dates: Data.gov lists 2026-03-13, while NASA Earthdata lists 2001 05-14, suggesting metadata inconsistency.
• Primary data collection period ended in 2001, limiting contemporary analysis.
