This post is the very definition of "spam".

"Science is not a paper." - ITN

This is a rebuttal to a non-existent claim.

I guess that anyone who previously believed that "science IS a paper." now has it on irrefutable authority that they were incorrect.

"Nitrogen isn't organic." - ITN

Unless it happens to be ORGANIC NITROGEN, which is a term that appears in the title of many of the papers referenced in this thread.

Again, we have it on irrefutable authority that "Nitrogen isn't organic."

True, if we are talking about nitrogen gas, nitrate nitrogen, ammonium nitrogen, or one of the other forms of INORGANIC nitrogen.

But ORGANIC NITROGEN, including proteins, amino acids, etc., IS exactly that - Organic nitrogen.

That's what they call it and that's what it is.

One troll doesn't get to unilaterally assign new definitions to long accepted terms.

All but one of those peer-viewed scientific papers was authored by the thread author, and have been cited hundreds of times in more recent peer-reviewed scientific papers.

A couple of them were even in the journal NATURE, perhaps the scientific communities most prestigious.

It hardly qualifies as "spam".

Keepit is correct.

Nobody has the authority to unilaterally proclaim what a word has to mean to anyone else.

And nobody, especially someone with no scientific education whatsoever, has the authority to unilaterally proclaim what "science" is or is not.

"There is no such thing as oxidation in chemistry.", for example.

This unsupported contrarian assertion defies centuries of a testable hypothesis shown to have a reproducible result, as per the Scientific Method.

My favorite: "There is no such thing as biogeochemistry."

This unilateral authoritative proclamation has been repeated in DOZENS of posts ("repetition fallacy"), as if reality can be wished away by simply denying it, over and over and over.

Some of us can actually comprehend what someone else is almost certainly trying to say when they use a term such as "fossil fuel" or "climate change".

This paper was published April 10, 2024

B. Adamczyk. 2024. Tannins and climate change: Are tannins able to stabilize carbon in the soil? Journal of Agricultural and Food Chemistry. Volume 72, Issue 16, pages 8928-8932.


This paper cites my tannin investigations and is highly relevant to the topic of carbon sequestration in agroecosystems.

The author and I are quite familiar with each other's research.

It was 35 years ago when I first became fully immersed in tannin (also known as polyphenol) research as a grad student at UC Berkeley.

At that time, anti herbivore defense was presumed to be the sole adaptive value for plants to make tannins, despite little evidence that they are effective.

Convoluted theories were created to explain why plant communities on highly infertile, acidic soils produced so much more tannin than plants on better soil, as somehow consistent with anti herbivore defense.

At that time, nobody considered how tannin production could benefit the plants that produce them through their impact on carbon and nitrogen cycling.

Tannins slow the decomposition of plant or soil organic matter they come into contact with. Tannins themselves are the substrate from which most soil humic acids are formed, having centuries long mean residence time in soil.

It is highly gratifying to see this finally reach the point where the application to address climate change is being so explicitly identified in the title of a new paper.

The following is not the abstract from the new paper. It is the first post of this thread.

Nutrient cycling dynamics of natural ecosystems can be mimicked in cropping systems to maximize carbon sequestration into soil organic matter, and minimize emissions of nitrous oxide. Tannin (aka polyphenol) chemical ecology provides insights into biogeochemical mechanisms that regulate carbon and nitrogen cycling.

The convergent evolution of tannin-rich plant communities has occurred on highly-infertile soils throughout the world. To acquire and conserve nitrogen, these plants allocate much of their organic carbon below ground to support symbiotic mycorrhizal fungi associated with their roots. Tannins in plant litter form recalcitrant complexes with protein, immobilizing this organic form of nitrogen and preventing mineralization. Mycorrhizal fungi produce enzymes that mobilize nitrogen from protein-tannin complexes, which is transferred directly to the root in organic nitrogen form. This short circuiting of the mineralization step in the nitrogen cycle prevents emission of nitrous oxide to the atmosphere, and prevents export of nitrate to groundwater or surface water. Allocation of photosynthate below ground to support mycorrhizal fungi also enhances sequestration of carbon into soil organic matter.

Tannins inhibit the oxidation of ammonium in soil to nitrate by nitrifying bacteria. This minimizes nitrous oxide emission as a by product of microbial nitrate reduction. Nitrogen release from tannin-rich litter is predominantly in the form of dissolved organic nitrogen rather than ammonium or nitrate. Dissolved organic nitrogen adsorbs to soil organic matter, minimizing leaching loss of nitrogen and retaining it in slow release form.

Tannins inhibit the decomposition of organic matter to substantially increase its mean residence in or above the soil. In the most extreme cases, equatorial rainforests form massive litter layers over acid white sand soils that are virtually devoid of nutrients or roots. One- or two-meters thick layers of litter in various stages of decomposition can accumulate above the mineral soil surface. This is despite warm, wet, well drained conditions that favor rapid decomposition. Exceptionally high tannin content in the vegetation of these forests enables them to create an enduring layer of organic matter above the soil surface, where virtually all the root growth and nutrient cycling occurs with high efficiency, and negligible losses.

Tannins themselves are the dominant substrate that transforms into soil humic acids. Humic acids enhance soil fertility in many ways, and their mean residence time in soil can be many centuries long. Tannins can comprise more than half the dry weight in foliage of tannin-rich species, and much of this represents sequestered carbon that will remain for a long time as stable soil organic matter.

We may not want to create thick litter layers above the topsoil in all our croplands. But polyphenol biogeochemistry can still be applied to increase carbon sequestration and decrease nitrous oxide emission. For example, tannin-rich organic matter can be combined with more rapidly decomposable crop residues or manure to slow decomposition and immobilize nitrogen into slowly mineralized organic form, as compost. Crop-mycorrhizal associations could be facilitated to sequester carbon and access recalcitrant soil nitrogen.

This paper was published April 10, 2024

B. Adamczyk. 2024. Tannins and climate change: Are tannins able to stabilize carbon in the soil? Journal of Agricultural and Food Chemistry. Volume 72, Issue 16, pages 8928-8932.


This paper cites my tannin investigations and is highly relevant to the topic of carbon sequestration in agroecosystems.

The author and I are quite familiar with each other's research.

It was 35 years ago when I first became fully immersed in tannin (also known as polyphenol) research as a grad student at UC Berkeley.

At that time, anti herbivore defense was presumed to be the sole adaptive value for plants to make tannins, despite little evidence that they are effective.

Convoluted theories were created to explain why plant communities on highly infertile, acidic soils produced so much more tannin than plants on better soil, as somehow consistent with anti herbivore defense.

At that time, nobody considered how tannin production could benefit the plants that produce them through their impact on carbon and nitrogen cycling.

Tannins slow the decomposition of plant or soil organic matter they come into contact with. Tannins themselves are the substrate from which most soil humic acids are formed, having centuries long mean residence time in soil.

It is highly gratifying to see this finally reach the point where the application to address climate change is being so explicitly identified in the title of a new paper.

The following is not the abstract from the new paper. It is the first post of this thread.

"I define my own words from time to time.." - Into the Night


Yes, you do, from time to time.

You won't allow a dictionary or scientific textbook to define ANY words.

Any time one of the many, many terms you never learned (because you never actually studied science) comes up, you call them "meaningless buzzwords".

And "from time to time" you make up your own definitions.

"Alligators are amphibians" is one of the most hilarious.

And even though you REFUSE TO BELIEVE that organic carbon even exists, you insist on trolling a thread that should be of very little interest to someone who doesn't know or care what organic carbon is.

"The idiots who cite your research aren't really scientists" - Into the Night

And who could possibly be more qualified than Into the Night to know who is really a scientist?

With such self evident omniscience and scientific infallibility, there is no need for you to support any of your contrarian assertions with evidence.

Your word alone is enough to prove that "Lignin is a carbohydrate" because you already decreed that "The entire plant is just carbohydrates and some protein."

You do a great public service with your trolling and spamming.

I genuinely hope that you get EVERYTHING you deserve for it.

Newest paper to cite "sealover" for published biogeochemistry research.

This paper came out on line 2 days ago, and will be published in the June, 2024 edition of the journal.

R. Xie, et al. 2024. Characterizing foliar phenolic compounds and their absorption features in temperate forests using leaf spectroscopy. ISPRS Journal of Photogrammetry and Remote Sensing. Volume 212, Pages 338-356.


More and more scientists are researching how phenolic compounds, most notably tannins (aka polyphenols) are correlated to multiple ecosystem processes, including carbon sequestration and stabilization of soil organic matter.

It is tedious to collect leaf samples, dry them, grind them up, extract them with solvents, and then assay them for total phenolic content or specific measure of tannins.

It is much more convenient to simply flash light of one wavelength or another on a leaf and record reflectance to calculate absorption. If that wavelength correlates well enough to phenolics, with a tolerable margin of error, it becomes possible to collect a thousand data points for the same amount of effort it would have taken to get a dozen data points with laboratory extractions.

itn,
You proclaim sooo many things without any defense of your statements. I doubt your proclamations mean anything to anyone except those few who are in agreement to your beliefs.
