| Zusammenfassung |
| Soil organic matter is a very important component of the Earth System and plays a significant
role in biogeochemical cycling and climate regulation. SOILRis a modeling framework that
contains a library of functions and tools for modeling soil organic matter decomposition,
microbial interactions, and radiocarbon dynamics under the Renvironment for computing. It
implements a variety of model structures and tools to represent carbon storage and release
from soil organic matter. In SOILR, organic matter decomposition is represented as a
nonlinear system of ordinary differential equations that generalizes the structure of most
compartment-based decomposition models. With this approach, it is simple to implement new
or existing models allowing comparisons of different model structures. A variety of
functions is also available to represent environmental effects on decomposition
rates, calculation of transit times, and radiocarbon incorporation in soil from the
atmosphere. In this presentation we will show 1) details about the mathematical
framework, 2) the computational implementation, and 3) examples on how it is
used. |
