Jerry Carlson's Notes from Dr. Don Huber presentation Dec. 16, 2009
NServe takes nitrous ammonius out of the rhizosphere. Other
Glyphosate takes entire groups of organisms out of the soil.
About 80% of our nitrogen losses are conversion to nitrous oxide, and
A lot of our ag chemicals are chelators. Tordon chelates copper.
Manganese availability depends on biological activity; it can only
Filaments of Take-all coat themselves with Manganese Oxide, MN04.
Improved nutrition reduces disease. Manure on wheat stimulates
Ergot sclerotia -- closes the capillaries.
Closest I’ve seen in my 55 years to a prolonged recovery period from
Inserting the RR gene in plant reduces Mn uptake efficiency. It adds
In soils that 15 years ago we were concerned about manganese
Iron, manganese available to plants only in reduced form (H).
Sulfur only available in oxidized form.
Gypsum gives you a good source of soluble CA plus soluble Sulfur.
Converting nitrate nitrogen into amine form, amino acids, can take
Fusarium wilt in melons and fruit -- go for Nitrate form and calcium.
nitrapyrin = N-Serv
Canadian: I’ve seen all those symptoms, just never associated them
Learn to watch for the symptoms; there’s a limited way the plant can
Glyphosate was patented as a metal chelator. Monsanto patented as a
EDTA is a chelator of 13.
Glyphosate penetrates readily, moves throughout the plant, chelates
Micronutrients tied up won’t be available for any future growth.
Once the initial flashing is over,
There is 1,000 times more glyphosate in the vascular system than
There’s an 80% reduction in Mn uptake.
Translocation of Fe, MN, Zn from root to shoot is reduced by more
Chelating means bonding. EDTA turns loose of minerals eventually,
Liberty Link has degradation within a two-day period.
All of the degredation products of glyphosate are toxic to the plant,
100% of the kill of plants with glyphosate is to open a secondary
Chelation of micronutrients -- accentuates drought stress. Three-
About a fourth of the gly moves into the soil via living roots.
We don’t know of any organism that uses gly as a nutrient source.
It sits there and accumulates for several years. It’s toxic to N-
We are starting to see glyphosate in grain, such as wheat planted
In Humans, we need a lot of micronutrients too.
Mandated phosmet insecticides chelated copper in cattle in England,
There may be some organism found to break it down, but haven’t heard
Glyphosate is an amino acid; it looked like it would biodegrade.
USDA shows mineral content of conventional and GMO grain is lower
Bob Kremer, University of Missouri, analyzes gly in the soil. Lab in
The compound hangs around a long time, both in the plant and in the
In the soil, desorbed by phosphorus.
Directly toxic to N-fixers
Richard Dick at Ohio State -- stimulation of fungus can immobilize up
If the politics win with the 15-year glyphosate review, we’ll see a
China has moved into RR cotton, they’re struggling.
We’ll have to import more food unless we reverse course on GMO/
When you’re in the hole and keep digging, it doesn’t do much good.
We should use it a lot more judiciously.
RR sugarbeets have very little resistance to rotting in the pile.
Glyphosate tolerant weeds are finding other pathways, not just the
We have aphid invasions because the amino acid is more appealing to
Alfalfa -- 20-ft. taproot. Could be translocating glyphosate into
We’ve had a 1500-fold increase in herbicide use, primarily because of
We’ve ignored the challenge. Now we’re approaching the consequences.
Texas -- corn fails after glyphosate cotton . Shikimate test out

My only successes were in building desert soils with biological
Davies spent his whole career into trying to reduce pathogens in
Whole groups of organisms disappear in a glyphosate environment.
Glyphosate reduces lignin content of soybeans. Also reduces amino
Reduces water efficiency. Takes twice as much water to produce a
How would I get rid of it? Will the RR gene transfer to unintended
Desorption of glyphosate with phosphate: Re-releases the compounds
Sudden Death Syndrome in soybeans is definitely related to the rise
Barney Gordon, Kansas. Gene present reduced yield effectivness. Took
Jeff Neal, journalist in England... had written story about myth of
Tissue tests may show adequate Mn, Zn, but doesn’t reveal if it’s
Mineral reduction in RR crops:
RR treated beans 45% lower in Mn, 26% lower in Ca.
Dan Skow, veterinarian with International Ag Labs in Fairmont, MN,
Vet: Brazilian corn tests in 2005 were much lower in fusarium molds;
Soil organisms kill the weed, not the glyphosate itself. That’s what
Diseases increased by Glyphosate.
Many of those which were controlled in the past are coming back.
And many of the wilts and other fungi are losing host specificity,
Manganese carbonate as a treatment to remediate manganese tied up.
When you have an iron defificency in the soil, you have a manganese
(My side note: In high iron soils of the southeast, maybe there’s
Tree trunk is a highly absorptive area for glyphosate.
