I don't know the details. But they seem to have done a lot of ag schools. You might try your college folks, and with them reach out to some of the ag orgs that were associated with this showing or their equivalent near you. I think they found this to be a success. Full house.
Here's the list of sponsors from my program. A couple of schools teamed up. https://www.screencast.com/t/zSn3m5e8HyLf
great read on the Bullshit that is TM and Drukers role at the University
My vocabulary might need tweaking as I when I said "groundwater runoff" I was thinking primaerily of what you call "surface runoff," but here's where you're wrong.
>Surface runoff can be generated either by rainfall or by the melting of snow or glaciers. Based on the hydrological cycle, runoff is flow from a drainage basin or watershed that appears in surface streams. The flow is made by parts of precipitation that falls directly into the stream, surface runoff, subsurface runoff, and groundwater runoff.
With that corrected have I made any other mistakes in my understanding of the role that tillage and application of fertilizer play in algeal blooms and oceanic dead zones?
