The development of PEWI has been funded through grants from Iowa State University Department of Agronomy, Iowa State University Extension and Outreach, Leopold Center for Sustainable Agriculture, USDA McIntire-Stennis Program (IOW05354, IOW05534), National Science Foundation (1924178), USDA National Institute for Food and Agriculture (2018-67019-27886), US Forest Service Northern Research Station, and The McKnight Foundation (12-323). We would not be able to provide PEWI without their generous support. THANK YOU!!!
