The  lecture James Adkins presented, on Wednesday October 2nd, focused on the evolution of irrigation being used in the agriculture field. Apparently, one of the first forms of irrigation was the hanging towers of Babylon. Throughout the history of Ag, the advancement of technology has allowed for all kinds of experiments  with irrigation. There have been irrigation systems powered by wind, walking on treadmills, gated pipes, and etc. In other countries, they still to this day use these techniques to make up for the lack of technological advancements. As for modern American society, we have switched over to center pivots and mobile irrigation systems.  The percentage of Delaware farmland that is irrigated is 30%; and out of that, only 50% of Sussex county is irrigated.
