`t` |
A vector containing the points in time where the solution is sought. |

`ks` |
A vector of lenght 5 containing the values of the decomposition rates for each pool. |

`p` |
A vector of length 13 containing transfer coefficients among different pools. |

`C0` |
A vector containing the initial amount of carbon for the 5 pools. The length of this vector must be 5. |

`In` |
A single scalar or data.frame object specifying the amount of litter inputs by time |

`xi` |
A scalar or data.frame object specifying the external (environmental and/or edaphic) effects on decomposition rates. |

`solver` |
A function that solves the system of ODEs. This can be |

`pass` |
if TRUE forces the constructor to create the model even if it is invalid |
