They elongate too quickly so the walls of the straws are weaker if given too much nitrogen at the wrong time. They fall over easily. You want them to grow more slowly with stronger straws.
They would grow even higher with fertilizer and then fall over in a storm. Well it increases the chance or percentage lost to that, it always happens to some degree even with modern varieties.
Which is funny enough, one of the main attributes Borlaug used in the green revolution: crossing Japanese dwarf wheat with modern bread wheat varieties to make the resulting wheat shorter.
The whole idea behind that was that (within reason) the more N you can pump into the crop, the more it will yield, but also the taller it will grow. Wheat is essentially an inverted pendulum when ripe, with about 60% of the above-ground biomass perched at the top.
The main thrust of modern crop breeding has been to create crops that you can successfully get to harvest under high-nutrition environments, without it literally falling over or succumbing to disease due to the turgid, fleshy growth. Even then, if you're applying more than maybe 150kgN/ha, you will be relying on plant growth regulators that inhibit auxin/gibberellin response to keep the plant under control.
At micromolar concentrations this may be true. There is plenty of Pb to go around in the soil and in the air from private aviation for such a minor micronutrient.
I also doubt elevating Pb levels in crops is at the top of many public health agendas.
It should be. It has the same effect on people - they grow too much too fast, but remain immature and fragile both mentally and physically. They do hit puberty very early though.
Yes, I did. The cognitive effects are devastating. The immature brains keep the high error tolerance that helps children to make sense of the world. This means that you are completely convinced that your answers are accurate, even when they are nonsense, as any problem that is below some kind of cognitive threshold simply doesn't register. You feel you have triple checked everything, and it's correct, it must be all the others who don't understand it. The entire progressivist mindset is a state of mind so infantile that it isn't normally seen, as normal children grew up from it before they acquired language. The results are catastrophic.
I really, really think you ate too many lead chips off the wall as a child.
The effects of neurotoxicity of lead is studied well enough at this point that anyone calling for _more_ lead in children's diet should themselves get tested for heavy metals or straight up admitted to the hospital,
There is NO SAFE LEVEL of exposure to lead. There is no safe amount of lead in blood. Any amount of lead in the organism is toxic and harmful and really, WTF are you even proposing.
Also in plants lead has exclusively negative effects. Negatively affects growth, photosynthesis, inhibits respiration, disrupts mineral nutrition, etc, etc. Worst of all, it accumulates so then it's transferred up the food chain.
Seriously, get yourself a blood test, something's waaaaay off, no one with IQ above 60-ish and with the access to internet should propose lead supplementing of children.
The studies are all wrong. That's the most dangerous thing about it. It's simply not possible for you as a victim to tell there is anything wrong with you, you can only tell in hindsight. The victims seem completely reasonable to each other, and the others are stupid, and don't understand their beliefs.
You must be trolling, this is just getting more dangerous than stupid.
There are NO safe levels provided by any reputable agency. 72μg you provide is about 20 times HIGHER than 3.5μg above which CDC recommends a corrective action.
"The studies are all wrong" -- show us your published work then, professor. I'm sorry but the level of the harmful communication in your comments would have, at this point, be supported by a massive body of evidence confirmed by irrefutable facts, followed by the Nobel prize in medicine.
I really think that if you're seriously thinking all that, you need help.
As I said, it's impossible to tell for the victims that there is anything wrong with them, or each other. In fact, there appears to be a threshold, below which the perception gets inverted, and the more severely affected are perceived as more intelligent. That's how we got those "resistance groups" who fought the regime and the brainwashed massess.
It needs lead too. It can't close completely, it can only reduce the process it regulates by about 80%, and it's like the difference between a partial eclipse and totality. Everything sort of runs at the same time, in a lousy way, instead of getting turned on and off as needed.
Why is that? I thought nitrogen is taken in through the roots, then distributed as other ground-based nutrition, regardless of the height.
