Fig. 6

Simulated water balance of two spring barley experiments conducted in 2016 (a) and 2017 (b). The model was parameterised with the soil physical data from the topsoil (0 m–0.4 m) and subsoil (0.4 m–2 m) (solid black line). Spring barley managed as described in Table 2 with simulated drainage and potential evapotranspiration (see Additional file 1). The blue dashed line represents the water balance if no drought had been induced by rainout shelters
