An evaluation of the success of extension and university outreach regarding lawn care showed that 17.0% of respondents made changes to use less fertilizer on their lawns, and 13.3% reduced their use of pesticides.
NPS pollution is a major threat to water quality, and the Changing Homeowner’s Lawn Care Behavior to Reduce Nutrient Losses in New England’s Urbanizing Watersheds project was designed to merge turf science, social science, and Extension knowledge and efforts into a concerted effort to change DIYers turf care behavior to protect water quality through the development and delivery of outreach and education.
The results indicate that 17.0% of respondents made changes to use less fertilizer on their lawns, and 13.3% reduced their use of pesticides. Only 4.3% of respondents used more fertilizer in the three years, and 5.6% used more pesticides. While most respondents did not change practices or do not use lawn chemicals at all, the changes that have occurred are in line with the goals of the project.
