Florida Waterkeepers United visit FDEP 2018-08-01

Seven of the fourteen Florida Waterkeepers visited the Florida Department of Environmental Protection (FDEP) to express our serious concern and a sense of urgency to protect and restore Florida’s rivers, coast, bays, estuaries, lakes, springs, and aquifer, especially about resiliency after hurricanes, harmful algal blooms, BMAPs, and phosphate mines. I congratulated Noah Valenstein on his meteoric rise: only two and a half years ago he was just starting as head of the Suwannee River Water Management District (SRWMD), and now he’s the head of FDEP.

L-R: Andy Hayslip (Tampa), Georgia Ackerman (Apalachicola), Marty Baum (Indian), Jen Lomberk (Matanzas), Drew Bartlett (FDEP), Whitney Gray (FDEP), Rick Frey (St. Marys), Lisa Rinaman (St. Johns), Noah Valenstein (Sec., FDEP), Shannon Blankinship

Crop nitrogen losses into Suwannee Basin

Here is a very interesting paper about increasing nitrogen from crops into the Suwannee River Basin and its springs (promoting algae growth), with actual data on how well best management practices (BMPs) are containing the runoff: Environmental Nitrogen Losses from Commercial Crop Production Systems in the Suwannee River Basin of Florida, by Rishi Prasad, George J. Hochmuth, PLOSOne, Published: December 1, 2016, http://dx.doi.org/10.1371/journal.pone.0167558


Fig 3. Comparison of A) environmental nitrogen losses (Nenvloss) from three crops (potato, sweet corn and silage corn) during four growing seasons (2010 to2013) and B) relationship between seasonal total N rates and environmental nitrogen losses at the study farm in the Middle Suwannee River Basin, Florida. Silage corn was not studied during 2013. Mean values of Nenvloss (represented by individual bars and their standard errors for the three crops) followed by different letters indicate significant difference at α = 0.05 level
