Modeling of priming effects for precise description of soil organic matter dynamics


From 10/2008 to 01/2009

Principal Investigator: Yakov Kuzyakov

The study is aimed on elaboration and experimental parameterization of a model of soil organic matter (SOM) decomposition considering activity of microbial biomass and availability of substrates. The effect of various substrates on SOM decomposition will be studied in incubation experiments with 14C labeled substances on two soils with contrast properties. The parameterization of the model will be done based on dynamics of total C and 14C in CO2 efflux from soil, microbial biomass and dissolved organic matter. The model will be used in further studies for process-based simulation of short-term C and N turnover in soil.
