Abstract
The aim of this project is to quantify the input, transfer and subsequent re-distribution of 13C labelled substrates into and through the components of the soil structure. This will be achieved by the innovative combination of soil micromorphological analysis with laser ablation isotope ration mass spectrometry. Use will be made of two labelled sources of C (pulse label and labelled litter). The outputs from this project will be quantification of the pathways from these two different labelled C inputs within the soil structure to assist with the overall modelling of the effects of biodiversity of carbon fluxes.
