Soil Pyrogenic and Organic Carbon Measurements in Amazon Forest Plots

Amazon Basin soil samples from 49 old-growth forest permanent plots provide measurements of pyrogenic carbon, organic carbon, and the ratio of %PyC to %Bulk Carbon. The dataset comprises 395 soil samples collected between 2015 and 2019. Measurements focus on soil fertility gradients within intact forests.

Use Cases

• Model relationships between soil pyrogenic carbon concentration and organic carbon levels across the fertility gradient.
• Analyze the spatial distribution of the %PyC to %Bulk Carbon ratio across 49 forest plots in the Amazon.
• Assess temporal changes in pyrogenic carbon soil concentration from samples taken between 2015 and 2019.
• Correlate soil carbon metrics with plot location to study biogeochemical patterns in old-growth forests.

Strengths

• Includes 395 soil samples from a systematic survey.
• Covers 49 distinct forest plots across the Amazon Basin.
• Provides multiple carbon metrics: pyrogenic carbon, organic carbon, and their ratio.

Limitations

• Sample size is limited to 395 cores, which may constrain statistical power for fine-scale analysis.
• Geographic scope is restricted to the Amazon Basin, limiting generalizability to other biomes.
• Data is static, covering only the 2015-2019 period with no ongoing updates.
