To restate the subject up for debate:

Are natural levels of phosphorus in soil a limiting element for plant growth?

The soil-as-a-complex-biological-system school of soil scientists say it is not. Moreover, they argue that adding phosphorus (among some other elemental amendments, i.e.nitrogen) is a bad idea in that it debilitates the natural root/microbiotic synergies.

What about hydroponic soil less plant growth?😁

I think it’s perfect... for the colony on Mars!

Relative to the complex Earthian ecosystem, and the minor considerations of clean air and water, sustainability of organic life, mitigation of adverse climate change, mental health, avoidance of plastics and fossil derived energy, and universal access by humanity in general, it might not check all the right boxes in the decision tree.

Not to mention it’s offtopic

Well actually the earth is hell bent on the removal or destruction of soil in general. Just pointing out that plants can live without soil1 There are so many recipes for poop potatoes, like potatoes aurotten..Flush away the phosphorus!

We are well on our way to flushing away the earths phosphorus!

Excellent history of the genesis and dominance of the misbegotten silo of NPK-think! (Oh, what a tangled web we unweave, when first we practice to simplify natural ecosystems...)

Quote
Indeed, pollution may be the strongest argument for reducing our dependence on mined phosphorus. “If we take all the phosphorus in the ground and move it into the system—ooh, we’re done,” Elser says. Some researchers have calculated that unchecked human inputs of phosphorus, combined with climate change, could eventually push much of the ocean into an anoxic state persisting for millennia. “I’m pretty sure we don’t want to do that,” Elser says, chuckling. Such events have occurred numerous times over Earth’s history and are thought to have caused several mass extinctions—for instance, when land plants evolved and sent a pulse of newly weathered phosphorus into the ocean.

The clear consensus among phosphorus experts is that humans must start mending the phosphorus cycle to reduce the environmental damage caused by pollution and to waste less of an increasingly scarce resource.

Time for a new model - hooray! Hip, hip, complex biological systems!!

Or so you hoped!

So you are agreeing with me that there is a phosphorus crisis! Plus in the word association game I made you say glyphosate that rhymes with My Phosphate.
It's funny or curious or both, that diversity of topics can lead to a convergence of subjects.

I was going to sarcastically quip that the necessary phosphorus was now being adequately provided by the breakdown of glyphosate, which has a phosphorus in the form of a phosphonic acid derivative. My.! updating of glyphosate lead me to this article that not only suggest how it could be directly detrimental to human, but that it has a huge toxicity to many of the bacterial and fungal species in soil, the damage of which is likely to be severe in loss of fertility/diversity. It was thought to be non-toxic to humans since we dont use the enzyme blocked by it, you guesed it glyphosate target enzyme (5-enolpyruvylshikimate-3-phosphate synthase) but we were not considering the effects on our bowel biomes!

So, to make matters worse, the glyphosate resistant weeds are now killed by ever larger doses of it, further deteriorating to bacterial and fungal soil biomes. I hope its not too late to reverse this trend, because it looks like a dead end path to me.
