Hi. I designed two different irrigation experiments in Xinjiang, China. The exp1 is full flood irrigation (100% flood irrigation fraction) and exp2 is 97% flood irrigation fraction and 3% sprinkler irrigation fraction. However, average irrigation water volume of exp1 is 617.82684 mm and average irrigation water volume of exp2 is only 252.82967 mm in the whole year. I don't know why there is such a big difference between these two values?
