When grape growers struggle with ailing crops, they call UA alumnus Geoff Hale for expert consultation. He pursued plant science after taking, and really liking, agriculture classes at the UA. Hale likens his work to that of a physician: "Plants have a basic ratio of needs of nutrients like nitrogen, phosphorous, potassium, calcium, iron. You don't want to be too high or too low in any element."
