| Zusammenfassung |
| Radiocarbon is an important tracer of the global carbon cycle that
helps to understand carbon dynamics in soils. It is useful to
estimate rates of organic matter cycling as well as the mean
residence or transit time of carbon in soils. We included a set of
functions to model the fate of radiocarbon in soil organic matter
within the SoilR package for the R environment for computing. Here
we present the main system equations and functions to calculate the
transfer and release of radiocarbon from different soil organic
matter pools. Similarly, we present functions to calculate the mean
transit time for different pools and the entire soil system. This
new version of SoilR also includes a group of data sets describing
the amount of radiocarbon in the atmosphere over time, data
necessary to estimate the incorporation of radiocarbon in
soils. Also, we present examples on how to obtain parameters of
pool-based models from radiocarbon data using inverse parameter
estimation. This implementation is general enough so it can also be
used to trace the incorporation of radiocarbon in other natural
systems that can be represented as linear dynamical systems. |
