Approximately 900 farmers in the U.S. Great Lakes Basin were interviewed in July 1977 to discover their opinions concerning the effect on water quality of certain agricultural activities, their attitudes about pollution abatement issues, their use of various conservation practices, and the factors which prompt their conservation activities. Survey results were analyzed and findings reported include: most farmers believe that no relationship exists between farm fertilizers/pesticides, manure, or eroded soil, and Great Lakse water quality; nearly 90% use conservation practices; 57% favor local government adminstered regulations; 70% favor voluntary controls; 75% say farmers need more information on controlling water pollution on their farms.
