Small Scale Spatial Variability Of Soil Organic Carbon At A Forest Side In Saxony PDF Download

Results showed that five sites had different spatial structure - Hardwood Hammock and Forest and Improved Pasture demonstrated both large variation at both coarse scale (67 and> 200 m) and very fine scale (2 m). Sandhill, Pineland and Dry Prairie were dominated by variation at very fine scales (2 and 7 m). All the five sites showed large variability at very fine scales, indicating the close coupling of SOC variation to structure and composition of vegetation. Lastly, the SOC change coupled with LULC and climatic factors over the past four decades was studied. Significant SOC accumulation was observed between 1965-1996 and 2008-2009 and concomitant LULC and LULC change significantly affected SOC change, less so climatic factors. The study improved the knowledge of the spatial and temporal variation of SOC in the complex soil-landscape continuum of Florida with implications for carbon cycling and sequestration, land resource management, and ecosystem service assessment.
