One way or another, I’m pretty sure that we need fertilizer. What is the source of GHG if the fertilizer is produced without natural gas or other fossil fuels?
NO2, methane from byproduct/digestion, soil carbon release from land overuse. Downstream methane release due to nitrate pollution.
The overwhelming majority of cropland is for “biofuel”, industrial chemicals and animal feed.
Industrial scale regenerative agriculture has lower yields in the short term, but doesn’t emit NO2 and leave behind a dust bowl (requiring clearing a new forest).
Eating crops directly rather than feeding cows is far more effective than changing fertilizer source. Eating organic crops uses a small fraction of the crop land that eating beef fed on intensively grown corn does.
Biointensive methods have many times the yield as industrial agriculture but are very labour intensive – automating them would save a lot more emissions.
Precision fermentation uses a tiny fraction of the land per unit of protein/nutrients.
Eating crops directly rather than feeding cows is far more effective than changing fertilizer source.
cows eat a lot of grass, and usually from land that isn’t suitable for crops. the silage they get is mostly parts of plants that people can’t or won’t eat.
Paltering.
Corn and soy grown for the purpose of large animal feed exceeds the amount of cropland used directly for human consumption in areas where <20% of calories and protein come from red meat.
almost no soy goes to cattle at all. calling me “paltering” while jumping from one segment of agriculture to another is just hypocritical rhetoric. try addressing the topic instead of characterizing me.
I said red meat. Pork and chicken need to go too, but that’snot as urgent.

i didn’t see any allusion to any animal except cattle here. am i reading too quickly?

your insults don’t change the text.
almost all soy (about 85%) is crushed for oil for human use. the vast majority of what’s fed to animals is the industrial waste from that process.
only 7% is fed directly to animals.
i don’t know the numbers for corn, but i do know that globally, about 2/3 of all crop calories go to people.

it’s crazy how much i’ve learned about soybeans, and never bothered to look into the numbers on corn. you’ll forgive me if i look for my own sources though.
calling me a shill doesn’t change the fact that 85% of all soy is crushed for oil

your inability to communicate without namecalling says a lot more about you than it does about what i’m saying.
meal is the majority of the weight of the soybean, but oil is about half the value of the soybean while only being 20% of the weight. they don’t process soybeans in meal presses: it’s processed in oil presses.
HEY YOUR SOYBEAN FACT SHEET REFLECTS THE GLOBAL NUMBERS REALLY CLOSELY!

what is fed to animals is the industrial waste from the oil processing. which is the comment i made that started your namecalling. i will accept an apology, but i will not tolerate any more insults.
