Abstract

Our aim is to use state-of-the-art techniques (chromatography, mass spectrometry (MS), nuclear magnetic resonance (NMR) in liquid and solid states, and 'wet' chemical methods) to identify and characterise the most active and most biologically stabilised fractions of soil organic matter (SOM). We shall study whole soils and physical fractions (free and intra-aggregate light fractions and clay, silt and sand fractions) from long-term sites at Rothamsted and world-wide. the results will be used as the building blocks for two new or modified SOM turnover models. We will investigate short-term N dynamics in the presence of added plant material using labelled material, physical fractionation and 15N NMR.
