Decomposition of green and rooibos tea in different soil types investigated by high-resolution NMR and FT-ICR-MS

摘要

Understanding the composition of natural organic matter(NOM)is vital to our understanding of how soils form and respond to climate or land use changes.NOM is a complex mixture of organic compounds produced by the biotic and abiotic decomposition of plant and animal remains.The shear complexity of NOM hinders drawing structure-function relationships needed to explain these processes.In this work,the decomposition of green and rooibos tea,as a potential proxy for the processes taking place in soils,is analysed in different soils by high-resolution analytical techniques.
