New article on the calibration of plant parameters in intercropping

The article by Bell et al. (2025) focuses on improving intercropping in the modelling process. Indeed, multi-species cropping systems are beneficial for agricultural soil health, but modelling interactions between species remains a challenge. The study aims to calibrate the barley parameters for the Stics model to take into account the presence of 0 to 8 associated crops. This calibration has improved the predictive performance of certain model outputs, demonstrating the potential of this approach to capture unsimulated interactions, but constraints remain regarding the applicability of the method in other contexts.
