"Stabilization and dynamics of soil organic matter in
response to long-term mineral and organic
With a projected world population of about nine billion people in 2050 and the increasing threat of global climate change, agriculture will be forced to develop management strategies that will ensure food security and increase the soil´s ability to store CO2. The fertility of a soil dpends heavily on the activity of soil microorganisms as the main drivers of all nutrient cycles. At the same time, soil microorganisms also contribute to the stabilization of organic carbon f.ex. by promoting aggregate formation. In addition, there is increasing evidence that soil organic matter (SOM) is predominantly of microbial origin. While both organic and mineral fertilization are assumed to increase soil organic carbon stocks, it is not yet fully understood how and to what extent these different fertilizers influence the composition and activity of soil microorganisms and hence, the turnover or stabilization of SOM. The Phd-thesis was intended to answer this question by analyzing soil samples from the Static Fertilization Experiment Bad Lauchstädt.
