Short summary
Soils store large amounts of carbon in soil organic matter, which comes from plant debris and roots. The mechanisms protecting it from biodegradation are not fully understood. Here, we carry out a size-fractionation of soil sampled on different dates in a field experiment. Using carbon and nitrogen content and spectroscopy and microscopy we conclude that organic matter enriched in nitrogen is preferentially protected from biodegradation and that clay minerals have differing protective abilities.
