what is being done to develop slow N release fertilizers to retain the nutrient at the site of need?
Jessica LeClair
01:02:11
Do you have information on the numbers of yard signs versus stickers selected by residents?
George Hoffman
01:07:51
What about supporting state laws that limit nitrogen components in fertilizer sold in stores?
Judy Rondeau
01:11:24
Thanks for your question, Jessica.
Stephen Klyce
01:12:50
Is there any significant contribution from commercial entities? Dairy, poultry, tree farms, grapes, potatoes, etc, etc.
Judy Rondeau
01:14:07
We distributed 169 bins stickers vs. 31 signs. However, due to the cost of the signs we only purchased 50, vs 250 stickers, so we had many more stickers to hand out. Anecdotally, I think people preferred the stickers because they were less visible than the signs, which was a bit counter to our goal to have our message displayed prominently.
Jessica LeClair
01:15:02
Thanks, Judy.

How do we reconcile these conclusions with the deadzone in Saybrook and Westbrook? Is it local shoreline fertilizing or river outflow or equally both?
Robert Johnston
01:21:31
One answer is that this project does not (yet) address some factors that can influence DO and dead zones, such as (1) delivery factors to embayments, i.e., how much of that nitrogen reaches particular waters, and (2) what happens to that N once it reaches the water, e.g., due to hydrodynamics. It also addresses only residential fertilization, not other possible sources of N delivery.
Robert Vasiluth
01:22:12
Can any agree in NY, with the great state of Connecticut to ban Methoprene aerial spraying of our shared interest?
Judy Rondeau
01:24:16
For those who are interested in some light reading, here is the link to the New England Regional Nitrogen & Phosphorus Fertilizer and Associated Management Practice Recommendations for Lawns based on Water Quality Considerations: https://www.uvm.edu/sites/default/files/Extension-Master-Gardener/NE_Recommendations_for_P_and_N_Lawns.pdf

Are these grants available as a reimbursable process for the homeowner, or does the money get distributed up front?
Stephen Klyce
01:32:01
Have you seen a measured decrease in N content in regions where these N sparing systems have been installed?
Jane Fasullo
01:34:20
I heard Katherine say the alternative systems work in low lying areas. But don't they need to have a water discharge field? How does that work when the level of the field is at or under high tide levels?
Maureen Murphy
01:35:31
Stephen Klyce--While there hasn't been any policy changes implemented, Miracle Gro has developed a Long Island specific fertilizer in response to advocates and community concerns. The fertilizer has a high content of slow release fertilizer.
Stephen Klyce
01:37:58
thank you, MM
David Newburn
01:40:33
Rob Johnston and I are writing a report to summarize our findings on lawn fertilizer behavior and N loading predictions. We should have this report prepared in June.
Jane Fasullo
01:46:20
Does the complication of maintaining an alternative system and the repeated servicing and cost keep people from switching?
Nico Calderon
01:48:48
Jane, the idea of it does, but in actuality, in ways it's easier to maintain because homeowners are required to have a maintenance contract where the system is taken care of by a professional--which could be like hauling your own trash vs having a trash service.
Jane Fasullo
01:49:10
Was there a look at the differences in pollution resulting from liquid and solid lawn fertilizers?
Peter Linderoth
01:49:40
Dr. Vaudrey's and colleague's N-loading model was referenced a few times today. Here is the link to the page (which includes the spreadsheet where you can select/compare embayments of interest): https://vaudrey.lab.uconn.edu/embayment-n-load/#

Thank you for attending today’s webinar everyone! As a reminder, a recording of the Nitrogen Pollution webinar will be emailed to registrants and attendees and will also be available on the Network website: https://www.liswaterquality.org/driving-local-actions-to-tackle-water-pollution/
Nico Calderon
01:51:33
Peter - we have a nice anecdote from Shelter Island on how quickly a clean water septic system can improve water quality if you are on a private well!
Stephen Klyce
01:52:50
Thanks for a great overview! The next steps are ahead…hooking up septics to sewer treatment, improving effluents and so on.
Judy Rondeau
01:54:17
To Peter's comments regarding lag time in seeing an embayment response to nitrogen reductions, USGS did a study on the effects of the sewering of a neighborhood on the Niantic River: https://pubs.usgs.gov/sir/2015/5011/

Good to hear about all the science behind this.
