cam someone spoon-feed me this meme? i don’t get it.
All plants require different levels nutrients to grow. If the same plant is grown repeatedly in the same soil then the soil will run out of the nutrients that plant needs and growing that plant becomes difficult. By rotating through plants with different nutrient requirements, the soil can maintain a sustainable balance of nutrients.
We now use the scientific method to argue ideas, but in the past ideas could just be laughed at if people thought they sounded dumb. People laughed at ideas like the sun being the center of the solar system and doctors needing to wash their hands before surgery. Refusal to accept these ideas held humanity back from technological advancement.
What’s that quote - something like “science progresses one funeral at a time”? Even scientists have their favourite theories that they’ll defend in the face of logic and evidence.
People didn’t just laugh at those ideas, they actively punished the people who proposed them.

Used to before the whole covid scam anyway. Now it’s “trust the science” which of course is an oxymoron. The whole point of science is that we don’t trust it, we verify it. And that wasn’t allowed.
You can’t really grow the same crop in the same field season after season (without fertiliser), because they’ll sap the specific nutrients they need from the soil. If you do that over and over eventually the soil wont have any food for that crop. Growing something different each season that takes different nutrients from the soil lets it recover the other ones. I don’t know how it recovers on its own, circle of life stuff probably. Modern farming can cheat by artificially replenishing the nutrients with fertiliser.
Soil requires fertilizer regardless, every harvest you export nutrients out of the soil that need to be replenished. The main purpose of crop rotation is to avoid proliferetion of diseases and pests.
some crops replenish nutrients, e.g. legumes directly fixing nitrogen from the air.
just because capitalist industrial agriculture is addicted to fossil fuel fertilizers doesn’t mean it’s the only way to farm.
Never thought about it that way, so if farmers (at this point probably mostly international big farming corporations) would just rotate their crops, they would not have to buy as much fertiliser, destroy the environment and probably a tonne of other disgusting stuff that comes with mono-cultures, like the excessive need for fertilisers? Yeah, that checks out 🥵 (“It’s too much work! Other crops don’t sell!”)
would just
Farmers have been rotating crops for hundreds of years man. Corporate farms rotate crops too. Step down off that soapbox for a moment.
The whole joke is that the person in the image would have made fun of the idea in ancient times, killing the food supply of early civilization and setting us all back by thousands of years.
As others have said, a monoculture will drain those specific nutrients.
Beans are kinda special being a nitrogen fixer. Lot of plants will drain nitrogen so we fertilize as supplement.
Plant beans, squash, and corn together and you won’t need to rotate your fields and the plants will form a sort of symbiosis working together.
Plants compete between them for resources, sorry but its idealistic nonsense to claim that they work together.
In addition to what Darth_Reagan said, it’s for pest control as well. By keeping a plant in the field for more than one season, you provide a food source for pests whose parents went there to feed the previous one. Some diseases only impact certain crops and can stick around in the dead matter only to attack your vulnerable new plants.
She is playing the part of the dumb antagonist saying Jeff is stupid for rotating his crops.
Somehow the dumb antagonist is 5000 years old. Humanity can be dumb lol.
thankfully, the assholes used to die off pretty quick back then.
How am I supposed to eat beans while watching Cars 2 now?
It doesn’t matter, if it was a good idea 17 other people also had it and at least one of them is a big enough asshole to try it
