Modelling soil organic carbon distribution in blanket peatlands at a landscape scale

Blanket peat and other moorland soils store the largest proportion of the soil organic carbon resource (SOC) in the United Kingdom. However, current understanding of the quantity and distribution of upland SOC is limited and approaches are needed to quantify carbon storage over large areas, whilst a...

Description
Summary:Blanket peat and other moorland soils store the largest proportion of the soil organic carbon resource (SOC) in the United Kingdom. However, current understanding of the quantity and distribution of upland SOC is limited and approaches are needed to quantify carbon storage over large areas, whilst adequately representing spatial variability at a smaller scale. This article presents a methodology for quantifying and mapping SOC distribution at a landscape scale in blanket peatlands on Dartmoor, South West England. Using stratified sampling, twenty-nine cores were taken from a range of depths within each of the soil types found in the study area. Depth was strongly correlated with bulk density (r2=0.70, P
