Isotope techniques were used for ET partitioning in an extreme agricultural system. The δE and δT were very similar, which is rarely seen in the literature. δE, δT, and δET increased initially, but decreased with further soil drying. About 46% of the irrigated water delivered to the crop was used as transpiration.
