Water Resources - Consider a corn yield of 7,000 kg hectare-1 (equivalent to ~100 bushels per acre). If 25 kg (one bushel) of corn consumed about 20 m3 of water during the growing season, what is the ratio of the weight of corn to the weight of water consumed? Where does most of the water end up? Calculate the minimum quantity of irrigation water required to grow the corn (1 hectare = 104 m2) if the corn is grown in Phoenix AZ (annual precipitation 7.66 in), and in Lincoln, NE (28.4in). Clearly state any assumptions you make.
Density of water is 999.97 kg/m
