Same soil, different climate: Crop model intercomparison on translocated lysimeters

Crop model intercomparison studies have mostly focused on the assessment of predictive capabilities for crop development using weather and basic soil data from same location. Still challenging is performance when considering complex interrelations between dynamics under a changing climate. The objective this study was to test agronomic environmental flux-related set models. aim predict weighing lysimeter-based (i.e., agronomic) water-related flux or state environmental) obtained monoliths that were taken their original environment translocated regions with different climatic conditions, after calibration at site. Eleven models deployed in study. lysimeter (2014–2018) Dedelow (Dd), Bad Lauchstädt (BL), Selhausen (Se) sites TERENO (TERrestrial ENvironmental Observatories) SOILCan network.
