What modelling methods are used by researchers in agronomy?

Our purpose is to investigate the methods used to design agricultural models and better identify how the agronomic research community exchanges information about modelling methods and develops new ones. More specifically, we are interested in better characterizing the extent to which such methods are use- and users- dependent. In fact some researchers make claims about the potential use of their model, but they rarely explain how they get information about use and users and take it into account in the model itself as pointed out by different authors
