Fragility of monoculture agriculture in varying water conditions

They don’t want to say “we don’t know,” but they don’t know. At least they have a working hypothesis about the collapse of the 2017 peanut crop in much of Florida: it has to do with variations in rainfall.

Bob Kemerait, Southeast Farm Press, 22 January 2018, Peanut collapse: Something happened but it’s not clear exactly why,

…For months, University of Florida’s Institute of Food and Agricultural Sciences Extension agents led by Anthony Drew, Mace Bauer and Dee Broughton had been sounding the alarm that an unprecedented collapse of the peanut crop was occurring across large areas of Florida’s production region. Symptoms of this collapse included stunted plants, late-season yellowing and leaves with distinctive marginal leaf necrosis. Where most severe, entire fields wilted in the weeks prior to harvest. Abysmal yields, off by as much as 45 percent, forced some to consider their future in farming if solution could not be found.

During the latter third of the season, Continue reading

Suwannee River: standard for dissolved organic matter

A primary objective of the WWALS Science Committee is to compile published scientific literature for the Suwannee basin. We are doing this using online search engines including the University of Georgia System Galileo program and Google Scholar. Remarkably, our searches have identified thousands of published scientific papers and reports that link to the keyword, “Suwannee”. Examination of many revealed that they describe research using dissolved organic matter isolated from the Suwannee River near Fargo, GA. This is the material that gives the water its special color.

Videos: Water, Agriculture, and Forestry; WWALS @ VSU 2017-03-28

You can’t use traditional models for the karst Floridan Aquifer; new and harsher pesticides are expected this summer; but you can help raise native species; and later this month you can go see many of them in Berrien County, plus WWALS monthly outings, the Withlacoochee and Little River Water Trail, and the Alapaha River Water Trail and some WWALS history.

Yeah, 2,4-D and Dicamba are head-scratchers --Tom Potter
Yeah, coming this summer, and they’re head-scratchers.

All this was at the quarterly WWALS public meeting, this one on Water, Agriculture, and Forestry at Valdosta State University, March 28, 2017.

Here are links to each WWALS video of each talk, with a few notes and a few extra pictures, followed by a WWALS video playlist. Continue reading
