      abstract     = {Agroecosystem models need to reliably simulate all
                      biophysical processes that control crop growth, particularly
                      the soil water fluxes and nutrient dynamics. As a result of
                      the erosion history, truncated and colluvial soil profiles
                      coexist in arable fields. The erosion‐affected
                      field‐scale soil spatial heterogeneity may limit
                      agroecosystem model predictions. The objective was to
                      identify the variation in the importance of soil properties
                      and soil profile modifications in agroecosystem models for
                      both agronomic and environmental performance. Four
                      lysimeters with different soil types were used that cover
                      the range of soil variability in an erosion‐affected
                      hummocky agricultural landscape. Twelve models were
                      calibrated on crop phenological stages, and model
                      performance was tested against observed grain yield,
                      aboveground biomass, leaf area index, actual
                      evapotranspiration, drainage, and soil water content.
                      Despite considering identical input data, the predictive
                      capability among models was highly diverse. Neither a single
                      crop model nor the multi‐model mean was able to capture
                      the observed differences between the four soil profiles in
                      agronomic and environmental variables. The model's
                      sensitivity to soil‐related parameters was apparently
                      limited and dependent on model structure and
                      parameterization. Information on phenology alone seemed
                      insufficient to calibrate crop models. The results
                      demonstrated model‐specific differences in the impact of
                      soil variability and suggested that soil matters in
                      predictive agroecosystem models. Soil processes need to
                      receive greater attention in field‐scale agroecosystem
                      modeling; high‐precision weighable lysimeters can provide
                      valuable data for improving the description of
                      soil–vegetation–atmosphere process in the tested
                      models.},
