Mikrobielle Nekromasse im Boden und deren Bedeutung für Bodenprozesse

Abstract

Understanding soil organic matter (SOM) formation is crucial for sustainable land use and mitigation of global change. SOM is perceived nowadays as a continuum of plant and microbial residues at various stages of decay. Microbial residues play a dominant role; plant-derived matter is processed by microbes to biomass and finally to necromass stabilised in SOM. Carbon storage thus depends on microbial energy metabolism and on environmental factors and minerals of the respective soils.
