Hybrid centrifugal spreading model to study the fertiliser spatial distribution and its assessment using the transverse coefficient of variation

•A virtual twin-disc spreader is modelled combining theoretical motion equations and statistical information.•Statistical distributions of input parameters are deduced from experimental measurements.•A Monte Carlo process reproduces the random variability of fertiliser spread pattern deposition.•Simulations demonstrate the influence of the application rate and the collection tray size on transverse CV.
