I want to understand this better. Are you saying that flooding a field loses the same amount of water to evaporation as other, more targeted, means of irrigation? Or are you saying "alfalfa itself uses the same amount of water regardless of irrigation methood." If it's the latter, that makes sense. A plant can only use so much, and that rate of use is consistent for a given crop, but that doesn't address the water not used by the alfalfa. Wouldn't flooding lose more water to evaporation than other irrigation methods?
