A generalized Ross infiltration model and the application on hole irrigation based on the biconjugate gradient stabilized algorithm

•The generalized Ross information model combined with BiCGSTAB (biconjugate gradient stabilized algorithm) and CMS (compressed matrix storage) can significantly improve the computational efficiency of the model.•The main variable transformation technique improves the mass conservation of the model. The adaptive adjustment of the time step can be effectively carried out by controlling the change in maximum effective saturation.•Without considering the evaporation of irrigation holes or with small evaporation of crop, if the fitting curve of time and infiltration volume determined by the indoor single-hole infiltration test is used to control the water volume, HAI (holes simultaneous irrigation) requires a longer infiltration time than HSI (holes alternating irrigation) to reach the same irrigation volume.
