ModVege is a mechanistic, dynamic pasture model. ModVege has four compartments representing the structural components of herbage:
Green vegetative (GV) - green leaves and sheath
Dead vegetative (DV) - dead leaves and sheath
Green reproductive (GR) - green stems and flowers
Dead reproductive (DR) - dead stems and flowers
The compartments are described using the:
Standing biomass (BM) [kg DM ha⁻¹]
Age of biomass (AGE) [°C d] (degree day - units of thermal time)
Organic matter digestibility (OMD)
Implementation#
The Python implementation of the ModVege pasture model adapted for use in this project was translated from Java to Python by Y. Chemin of JRC Ispra. This Python implementation was originally published as public domain software on GitHub under the Unlicence license. The Java model was provided by R. Martin of INRAE UREP Clermont-Ferrand for the original Python implementation. The original ModVege pasture model was developed by Jouven et al.
