Fig. 7 Real irrigation scheduling (2019). Precipitation distribution, effective rainfall, irrigation
scheduling and evolution of the soil moisture depletion level throughout the crop season with respect
to the Allowable Depletion Level (ADL), Readily Available Water (RAW) and Total Available Water
(TAW
crop were 711 mm (Table 1), the theoretical irrigation needs at critical moments (see
Eq. 9) were more restrictive than the IWA n .
With the RDI strategy, the total water applied for irrigation would be 403 mm, a
20% reduction with respect to the previous strategies as well as greater use of the
water stored in the soil. ER takes a value of 266 mm, slightly higher than the previous
scenarios.
