Will Hubbard Brook Soils Be a Source or Sink of Carbon in a Changing Climate? Chris Johnson Syracuse University

Carbon in HBEF Soils

Climate Change and Soil Carbon Higher soil temperatures → Faster decomposition Higher soil moisture → Faster decomposition

Climate Change and Soil Carbon Higher soil temperatures → Faster decomposition Higher soil moisture → Faster decomposition Decreased Soil C Pools

Climate Change and Soil Carbon Higher soil temperatures → Faster decomposition Higher soil moisture → Faster decomposition Decreased Soil C Pools Higher soil temperatures → Longer growing season Higher soil moisture → Less frequent water stress

??? Climate Change and Soil Carbon Higher soil temperatures → Faster decomposition Higher soil moisture → Faster decomposition Decreased Soil C Pools ??? Increased Soil C Pools Increased Litterfall Increased Tree Growth Higher soil temperatures → Longer growing season Higher soil moisture → Less frequent water stress

Models and Parameterization CENTURY: Comprehensive; includes plant-growth sub-model, incorporates CO2 effects. RothC: Relatively simple; litter inputs manually entered. Both models were parameterized using data from Watersheds 5 (pre-cutting) and 6. Model Measured % Difference Soil C Pool (g C m-2): CENTURY 6888 6920 -0.46% Soil C Resp. (g C m-2 yr-1): RothC 392 400 -2.00%

Validation Model performance was tested using data from the Watershed 5 clear-cutting experiment

Prediction If changing climate and CO2 have no effect on forest productivity… -8% -30% HBEF soils are likely to be a net source of Carbon

Prediction If forest productivity responds positively to changing climate and CO2 +7% +2% HBEF soils may be a modest net sink for Carbon

Conclusions Both CENTURY and RothC are viable soil carbon models for HBEF soils. The source/sink behavior of soil carbon depends on the response of forest productivity to increased CO2 and changing climate.
