Climatic and Edaphic Drivers of Soil Organic Carbon and Pyrogenic Carbon Stocks Across Elevation and Disturbance Gradients in Colombian Andean Forests. [PDF]

open access: yesGlob Chang Biol
This study examined soil organic carbon (SOC) and pyrogenic carbon (PyC) stocks in tropical Andean soils across elevation and disturbance gradients in Colombia. SOC stocks to 100 cm depth averaged 433.10 Mg C ha−1 while PyC was 34.13 Mg C ha−1. Key drivers of PyC stocks include soil clay (%), mean annual precipitation (PA), pH, Ca, and NDVI, which ...
