Due to concerns regarding non-point source pollution of water bodies from lawn care maintenance, Florida has recently developed a Green Industries Best Management Practices Manual. Proper fertilizer application and handling has been shown to reduce any risk of nonpoint source pollution, while mishandling or over-application of fertilizer may lead to considerable leaching or run-off of nutrients. An educational program has also been developed to get the information on how to follow the manual to the lawn care workforce. To date, approximately 1,700 lawn care workers have been certified through this training program. Responses to the program have been favorable, with 96 and 99% of attendees crediting the training with increasing their knowledge in 2003 and 2004, respectively. Post test scores increased by 15% in 2004. Because this program is not mandatory at this time, it has in some cases been difficult to get good attendance. This is being addressed by increasing public awareness about the potential for environmental harm if proper lawn care practices are not followed. A certification program is in place that will enable attendees to use their completion of the course in marketing.
