Perennial crops and Midwest water usage

The Great Lakes Bioenergy Center has released a study looking at how 'second gen' perennial biofuel crops such as switchgrass and other perennial grasses use water and affect overall Midwestern rainfall balance. The researchers conclude that in a humid Midwestern climate with well-drained soils, perennial use water at roughly the same rate as corn.

More information is available from Biofuels Digest Researchers say perennial crops could use same water as corn in Upper Midwest (7/6/15) and from the Great Lakes Bioenergy Center -  Perennial biofuel crops use water at levels similar to corn.
