Making Recommendations for Lawn Fertilizer Applications

Many Connecticut parks, golf courses, and residential landscapes are located near ponds, lakes, rivers and

coastal waters. These surface waters can be degraded by nutrient loss resulting from over-application or

improper application of fertilizers to home lawns and other turfgrass areas.  Groundwater can also be

contaminated from nutrient lost from lawns.  Recent research has provided data that should change the way 

advise clients in fertilizing and managing lawns and other turfgrass areas.
