John Quarterman on the Withlachoochee (audio)

Back at the end of March at a river conference in Roswell, Georgia, I was interviewed for a podcast. Here’s the audio, and here’s the blurb they included:

John Quarterman on the Withlachoochee
Monday, July 9th, 2012

John S. Quarterman was born and raised in Lowndes County, where he married his wife Gretchen. They live on the same land where he grew up, and participate in local community and government.

NPS talks with Quarterman and his observations on starting and strengthening a Withlachoochee Riverkeeper organization at Georgia River Network‘s 2012 Weekend for Rivers.

The water organization has since been incorporated as the Georgia non-profit WWALS Watershed Coalition:

WWALS is an advocacy organization working for watershed conservation of the Willacoochee, Withlacoochee, Alapaha, and Little River Systems watershed in south Georgia and north Florida through awareness, environmental monitoring, and citizen advocacy.

PS: They also recorded another podcast which starts out on what may sound like a completely different topic, but which is actually quite related.

Mutant Pigweed vs. Glysophate-Resistant Corn, Soybeans, and Cotton

It’s a funny thing about monocultures. They’re highly vulnerable to anything that affects that particular variety. Dr. Mae-Wan Ho writes:
The scene is set at harvest time in Arkansas October 2009. Grim-faced farmers and scientists speak from fields infested with giant pigweed plants that can withstand as much glyphosate herbicide as you can afford to douse on them. One farmer spent US$0.5 million in three months trying to clear the monster weeds in vain; they stop combine harvesters and break hand tools. Already, an estimated one million acres of soybean and cotton crops in Arkansas have become infested.

The palmer amaranth or palmer pigweed is the most dreaded weed. It can grow 7-8 feet tall, withstand withering heat and prolonged droughts, produce thousands of seeds and has a root system that drains nutrients away from crops. If left unchecked, it would take over a field in a year.

Meanwhile in North Carolina Perquimans County, farmer and extension worker Paul Smith has just found the offending weed in his field [3], and he too, will have to hire a migrant crew to remove the weed by hand.

Diesel Exhaust as Fertilizer

I don’t know how well this actually works, but it’s an interesting idea if it does:
The system’s Canadian inventor Gary Lewis claims that injecting a stream of cooled exhaust gases into cultivated soil will enrich its fertility by boosting carbon and nitrogen levels.

This will encourage microbes that consume greenhouse gases and convert them into plant nutrients.

In turn, this will reduce fertiliser use, soil acidity and the amount of carbon dioxide entering the atmosphere.

That article is from last year. This year, the farm trying this, Ian Linklater, reports success: Continue reading →
