Irrigation amounts can vary widely by year and crop. In 2004 there were period of moderate crop stress in late spring. Crops like corn that have critical growth periods during that time received higher than usual amounts of irrigation. Rainfall was well above normal in late summer.
High value species like recreational turf grass on golf courses and athletic fields, as well as plant nurseries and sod farms, require water during a longer periods of the year than row or vegetable crops.
