Soil Nutrient and Pyrogenic Carbon Measurements Across Colombian Andean Forest Gradients

Colombian Andean ecosystems data includes soil nutrients like pH, phosphorus, and texture, plus pyrogenic carbon and bulk density. Measurements were collected from 27 forest monitoring plots between 2019 and 2022 across altitudinal and human perturbation gradients. The dataset supports analysis of soil characteristic changes following disturbance.

Use Cases

• Model relationships between soil pH, available phosphorus, and pyrogenic carbon (Cpyc) across perturbation levels.
• Analyze soil texture composition (sand, clay, silt) and bulk density variations along the altitudinal gradient.
• Assess Total Organic Carbon (TOC) and Cpyc%/CBulk ratios to study carbon dynamics in human-modified forests.
• Correlate exchangeable cations (Ca, Mg, K, Na) and dry weight of roots with forest perturbation intensity.

Strengths

• Data from 27 spatially distinct forest monitoring plots (0.5 ha each) provides geographic breadth.
• Covers a defined temporal range from 2019 to 2022.
• Includes multiple analytical soil variables: nutrients, texture, pyrogenic carbon, and physical properties.
• Structured along two explicit gradients: altitudinal (lowland to highland) and forest perturbation (low to high).

Limitations

• Sample size is limited to 27 plots, which may constrain statistical power for complex multivariate models.
• Unknown row count and column structure prevents assessment of dataset scale and granularity prior to download.
