Turfg.rass Research Videos i IFAS Research 7/8/13 10:51 AM <br /> a public meeting in Citra,where much of the footage was shot. The video includes a question-and-answer session with the <br /> scientists, and comments from Andy Rackley, director of agricultural environmental services for FDACS. <br /> Several researchers mentioned that their findings raised new questions and pointed out the need for additional research on topics <br /> including the use of biosolids and other organic nitrogen sources,the use of reclaimed water,turfgrass phosphorus requirements, <br /> and the effects of summertime fertilizer bans. <br /> "We're in some conversations with DEP(the state Department of Environmental Protection)still about moving forward with some <br /> additional data analysis," Unruh said. <br /> He also noted that the results suggest OF/IFAS' nutrient recommendations for zoysiagrass may need to be modified, but any <br /> changes to those nutrient recommendations must come about through a vetting process by the Plant Nutrient Oversight Committee, <br /> a team of administrators and scientists who review all nutrient recommendations from UF/IFAS. <br /> Extension personnel will be trained to help them communicate the findings to homeowners and there may be additional public <br /> workshops,Trenholm said. <br /> Homeowners with unhealthy lawns should contact county extension personnel to discuss the problem and not automatically assume <br /> that fertilizer is needed, Cisar said. <br /> "If you have a lawn that's in bad shape, it makes sense to ascertain why,"he said."It may be that the grass needs fertilizer but it <br /> could be something else, like a lack of proper irrigation, proper mowing height,or the grass isn't getting enough light." <br /> +I Feedback <br /> http://research.ifas.ufl.edu/communications/turfgrass-research-videos Page 2 of 2 <br /> 13 -(a9 <br />
