Purdue Collaborative On-Farm Research
Indiana crop producers have incorporated the use of GPS Based Technology into their
operations. Experience at the Davis Purdue Ag Center and other PACs has helped
researchers in developing a Purdue Collaborative On-Farm Research Program where
Indiana crop producers, Indiana Certified Crop Advisers, county Purdue Extension
Educators, and campus Purdue Extension field crops specialists work together to come up
with answers to farming’s challenging questions. See web site for more information
